+  The GNU Affero General Public License is a free, copyleft license for
+software and other kinds of works, specifically designed to ensure
+cooperation with the community in the case of network server software.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+our General Public Licenses are intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
+
+  Developers that use our General Public Licenses protect your rights
+with two steps: (1) assert copyright on the software, and (2) offer
+you this License which gives you legal permission to copy, distribute
+and/or modify the software.
+
+  A secondary benefit of defending all users' freedom is that
+improvements made in alternate versions of the program, if they
+receive widespread use, become available for other developers to
+incorporate.  Many developers of free software are heartened and
+encouraged by the resulting cooperation.  However, in the case of
+software used on network servers, this result may fail to come about.
+The GNU General Public License permits making a modified version and
+letting the public access it on a server without ever releasing its
+source code to the public.
+
+  The GNU Affero General Public License is designed specifically to
+ensure that, in such cases, the modified source code becomes available
+to the community.  It requires the operator of a network server to
+provide the source code of the modified version running there to the
+users of that server.  Therefore, public use of a modified version, on
+a publicly accessible server, gives the public access to the source
+code of the modified version.
+
+  An older license, called the Affero General Public License and
+published by Affero, was designed to accomplish similar goals.  This is
+a different license, not a version of the Affero GPL, but Affero has
+released a new version of the Affero GPL which permits relicensing under
+this license.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU Affero General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Remote Network Interaction; Use with the GNU General Public License.
+
+  Notwithstanding any other provision of this License, if you modify the
+Program, your modified version must prominently offer all users
+interacting with it remotely through a computer network (if your version
+supports such interaction) an opportunity to receive the Corresponding
+Source of your version by providing access to the Corresponding Source
+from a network server at no charge, through some standard or customary
+means of facilitating copying of software.  This Corresponding Source
+shall include the Corresponding Source for any work covered by version 3
+of the GNU General Public License that is incorporated pursuant to the
+following paragraph.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the work with which it is combined will remain governed by version
+3 of the GNU General Public License.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU Affero General Public License from time to time.  Such new versions
+will be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU Affero General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU Affero General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU Affero General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY
+APPLICABLE LAW.  EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT
+HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
+OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
+THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
+IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
+ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
+GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
+USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
+DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
+PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
+EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
+SUCH DAMAGES.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     END OF TERMS AND CONDITIONS
+
+            How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU Affero General Public License as published by
+    the Free Software Foundation, either version 3 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU Affero General Public License for more details.
+
+    You should have received a copy of the GNU Affero General Public License
+    along with this program.  If not, see <https://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If your software can interact with users remotely through a computer
+network, you should also make sure that it provides a way for users to
+get its source.  For example, if your program is a web application, its
+interface could display a "Source" link that leads users to an archive
+of the code.  There are many ways you could offer source, and different
+solutions will be better for different programs; see section 13 for the
+specific requirements.
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU AGPL, see
+<https://www.gnu.org/licenses/>.

+<h1 align="center">Kimai - time-tracker</h1>
 
-## Introduction
+Kimai is a professional grade time-tracking application, free and open-source. 
+It handles use-cases of freelancers as well as companies with dozens or hundreds of users. 
+Kimai was build to track your project times and ships with many advanced features, including but not limited to:
 
-This is the reloaded version of the open source timetracker Kimai.
-Right now its in an early development phase, its usable but some advanced features from Kimai v1 are missing by now.
+JSON API, invoicing, data exports, multi-timer and punch-in punch-out mode, tagging, multi-user - multi-timezones - multi-language ([over 30 translations existing](https://hosted.weblate.org/projects/kimai/)!),
+authentication via SAML/LDAP/Database, two-factor authentication (2FA) with TOTP, customizable role and team permissions, responsive design,
+user/customer/project specific rates, advanced search & filtering, money and time budgets, advanced reporting, support for [plugins](https://www.kimai.org/store/)
+and so much more.
 
-Kimai v2 has nothing in common with its predecessor [Kimai v1](http://www.kimai.org) besides the basic ideas of time-tracking and the current development team.
-It is based on a lot of great frameworks. Special thanks to [Symfony v4](https://github.com/symfony/symfony), [Doctrine](https://github.com/doctrine/),
-[AdminThemeBundle](https://github.com/avanzu/AdminThemeBundle/) (based on [AdminLTE](https://github.com/almasaeed2010/AdminLTE/)).

-- the [usual Symfony application requirements](http://symfony.com/doc/current/reference/requirements.html)
-- Kimai needs to be installed in the root directory of a domain or you need to [recompile the frontend assets](var/docs/developers.md)
-
-## Documentation & Roadmap
-
-Looking for more information about using Kimai? Check out our more detailed [documentation](var/docs/).
-
-You can see our development roadmap for the future in the [Milestones](milestones/) sections,
-current work is organized in the [Project](projects/) planning boards.
-Our roadmap is open for changes and input from the community, please [sent us](issues/) your ideas and questions.
+- PHP 8.1 minimum
+- MariaDB or MySQL
+- A webserver and subdomain (subdirectory is not supported)
+- PHP extensions: `gd`, `intl`, `json`, `mbstring`, `pdo`, `tokenizer`, `xml`, `xsl`, `zip`
 
 ## Installation
 
-First, install Git and [Composer](https://getcomposer.org/doc/00-intro.md) if you haven't already. Then clone this repo:
+- [Recommended setup](https://www.kimai.org/documentation/installation.html#recommended-setup) — with Git and Composer
+- [Docker](https://hub.docker.com/r/kimai/kimai2) — containerized by [@tobybatch](https://github.com/tobybatch/kimai2)
 
-```bash
-git clone https://github.com/kevinpapst/kimai2.git
-cd kimai2/
-```
+There are also documentations for:
+- [developer setups](https://www.kimai.org/documentation/developers.html) — on your local machine
+- [shared hostings](https://www.kimai.org/documentation/installation.html#shared-hosting) — the least favorable option
+- [Synology](https://www.kimai.org/documentation/synology.html) — you could try to host the Docker version instead 
+- [1-click installer](https://www.kimai.org/documentation/installation.html#hosting-and-1-click-installations) — hosted environments 
 
-The next steps depend in which environment you want to use Kimai, you can choose between development or production mode.
+And if you don't want to host Kimai, you can use [the Cloud version](https://www.kimai.cloud/) of it.
 
-### Installation (development)
+### Updating Kimai
 
-Lets prepare the environment by installing all dependencies:
+- [Update Kimai](https://www.kimai.org/documentation/updates.html) — get the latest version
+- [UPGRADING guide](UPGRADING.md) — version specific steps
 
-```bash
-composer install
-```
+### Plugins
 
-The default installation uses a SQLite database, so there is no need to create a database for your first tests.
-Our default settings will work out-of-the-box, but you might want to adjust the `.env` values to your needs.
-You can configure your database through your environment (e.g. Webserver, Cloud-Provider) or in your `.env` file:
-```
-DATABASE_PREFIX=kimai2_
-DATABASE_URL=sqlite:///%kernel.project_dir%/var/data/kimai.sqlite
-APP_ENV=dev
-APP_SECRET=some_random_secret_string_for_your_installation
-```
+- [Plugin marketplace](https://www.kimai.org/store/) — find existing plugins here
+- [Developer documentation](https://www.kimai.org/documentation/developers.html) — how to create a plugin
 
-The next command will create the database and the schema:
-```bash
-bin/console doctrine:database:create
-bin/console doctrine:schema:create
-```
+## Roadmap and releases
 
-Lets bootstrap your environment by executing this commands (which is only available in dev environment):
-```bash
-bin/console kimai:reset-dev
-```
+You can see a rough development roadmap in the [Milestones](https://github.com/kimai/kimai/milestones) sections.
+It is open for changes and input from the community, your [ideas and questions](https://github.com/kimai/kimai/issues) are welcome.
 
-You just imported demo data, to test the application in its full beauty and with several different user accounts and permission sets.
+Release versions will be created on a regular basis, every couple of weeks latest.
+Every code change, whether it's a new feature or a bugfix, will be done on the `main` branch.
 
-You can now login with these accounts:
+For the time being and until 2.0 is widely adopted, the [1.x branch](https://github.com/kimai/kimai/tree/1.x) will receive bug fixes.

+## Contributing
 
-Demo data can always be deleted by dropping the schema and re-creating it.
-ATTENTION - this will erase all your data:
+You want to contribute to this repository? This is so great!
+The best way to start is to [open a new issue](https://github.com/kimai/kimai/issues) for bugs or feature requests or a [discussion](https://github.com/kimai/kimai/discussions) for questions, support and such.
 
-```bash
-bin/console doctrine:schema:drop --force
-bin/console doctrine:schema:create
-```
+In case you want to contribute, but you wouldn't know how, here are some suggestions:
 
-The `kimai:reset-dev` command can always be executed later on to reset your dev database and cache.
+- Spread the word: More user means more people testing and contributing to Kimai, which in turn means better stability and more and better features. Please vote for Kimai on any software platform, you can toot or tweet about it, share it on LinkedIn, Reddit or any of your favorite social media platforms. Every bit helps!
+- Answer questions: You know the answer to another user's problem? Share your knowledge.
+- Something can be done better? An essential feature is missing? Create a feature request.
+- Report bugs makes Kimai better for everyone.
+- You don't have to be programmer, the documentation and translation could always use some attention.
+- Sponsor the project: free software costs money to create!
 
-There is no need to configure a virtual host in your web server to access the application for testing.
-Just use the built-in web server for your first tests:
+There is one simple rule in our "Code of conduct": Don't be an ass!
 
-```bash
-bin/console server:run
-```
+### Credits
 
-This command will start a web server for Kimai. Now you can access the application in your browser at <http://127.0.0.1:8000/>.
-You can stop the built-in web server by pressing `Ctrl + C` while you're in the terminal.
+Kimai is based on modern technologies and frameworks such as [PHP](https://www.php.net/),
+[Symfony](https://github.com/symfony/symfony) and [Doctrine](https://github.com/doctrine/),
+[Bootstrap](https://github.com/twbs/bootstrap) and [Tabler](https://tabler.io/),
+and [countless](composer.json) [others](package.json).
 
-To re-generate the frontend assets ([more information here](var/docs/developers.md)), execute:
-```bash
-yarn install
-npm run prod
-```
-
-### Installation (production)
-
-Lets prepare the environment by installing all dependencies:
-
-```bash
-composer install --no-dev
-```
-
-Make sure the [directories are read and writable by your webserver](https://symfony.com/doc/current/setup/file_permissions.html):
-```bash
-chown -R www-data var/
-chmod -R 777 var/
-```
-
-The database to use is up to you, but we would not recommend using the default SQLite database for production usage.
-Please create your database and configure the connection string in your environment, e.g. with the `.env` file:
-```
-APP_ENV=prod
-DATABASE_URL=mysql://db_user:db_password@127.0.0.1:3306/db_name
-APP_SECRET=insert_a_random_secret_string_for_production
-```
-
-Create the database schemas and warm up the cache (as webserver user):
-```bash
-bin/console doctrine:schema:create
-sudo -u www-data bin/console cache:warmup --env=prod
-```
-
-Create your first user with the following command. You will be asked to enter a password afterwards.
-
-```bash
-bin/console kimai:create-user username admin@example.com ROLE_SUPER_ADMIN
-```
-_Tip: You can skip the "create user" step, if you are going to import data from Kimai v1._
-
-For available roles, please refer to the [user documentation](var/docs/users.md).
-
-> **NOTE**
->
-> If you want to use a fully-featured web server (like Nginx or Apache) to run
-> Kimai, configure it to point at the `public/` directory of the project.
-> For more details, see:
-> http://symfony.com/doc/current/cookbook/configuration/web_server_configuration.html
-
-That's it, you can start time-tracking :-)
-
-### Importing data from Kimai v1
-
-Before importing your data from a Kimai v1 installation, please read the following carefully:
-
-- Data from the existing v1 installation is only read and will never be changed
-- Data can only be imported from a Kimai installation with at least `v1.0.1` and database revision `1388` (check your `configuration` table)
-- Kimai v1 has support for activities without project assignment, which Kimai v2 doesn't support. Unattached activities will be created for every project that has a linked activity in any of the imported timesheet records
-- Rates and fixed-rates are handled in a completely different way and for now only the timesheet record total amounts are imported
-- Customers cannot login and no user accounts will be created for them
-- The customers country has to be manually assigned afterwards, as there is no field in Kimai v1 for that
-- You have to supply the default password that is used for every imported user, as their password will be resetted
-- Data that was deleted in Kimai v1 (user, customer, projects, activities) will be imported and set to `invisible` (if you don't want that, you have to delete all entries that have the value `1` in the `trash` column before importing)
-
-A possible full command for import:
-```bash
-bin/console kimai:import-v1 "mysql://user:password@127.0.0.1:3306/database?charset=utf8" "db_prefix" "password" "country"
-```
-
-It is recommended to test the import in a fresh database. You can test your import as often as you like and fix possible problems in your installation.
-A sample command could look like that:
-```bash
-bin/console doctrine:schema:drop --force && bin/console doctrine:schema:create && bin/console kimai:import-v1 "mysql://kimai:test@127.0.0.1:3306/kimai?charset=latin1" "kimai_" "test123" "de"
-```
-That will drop the configured Kimai v2 database schema and re-create it, before importing the data from the `mysql` database at `127.0.0.1` on port `3306` authenticating the user `kimai` with the password `test` for import.
-The connection will use the charset `latin1` and the default table prefix `kimai_` for reading data. Imported users can login with the password `test123` and all customer will have the country `de` assigned.
-
-## Extensions for Kimai 2
-
-As Kimai 2 was built on top of Symfony, it can be extended like every other Symfony application.
-We call these extensions bundles, but you might also know them as add-ons, extensions or plugins.
-
-All available Kimai 2 bundles can be found at the [Kimai recipes](https://github.com/kimai/recipes) repository.
-
-## Developer
-
-If you want to develop for Kimai 2 please read the following documentation:
-
-- an example on how to extend Kimai 2 can be found in this [GitHub repository](https://github.com/kevinpapst/kimai2-invoice)
-- the [developer documentation](var/docs/developers.md) is available both on GitHub and your local installation

+# Upgrading Kimai
+
+_Make sure to create a backup before you start!_ 
+
+Read the [updates documentation](https://www.kimai.org/documentation/updates.html) to find out how 
+you can upgrade your Kimai installation to the latest stable release.
+
+Check below if there are more version specific steps required, which need to be executed after the normal update process.
+Perform EACH version specific task between your version and the new one, otherwise you risk data inconsistency or a broken installation.
+
+## [2.0](https://github.com/kimai/kimai/releases/tag/2.0)
+
+**!! This release requires minimum PHP version to 8.1 !!**
+
+Developer read the full documentation at [https://www.kimai.org/documentation/migration-v2.html](https://www.kimai.org/documentation/migration-v2.html).
+
+- **All plugins need to be updated**: delete all previous version from your installation (`rm -r var/plugins/*`) before updating!
+- Invoice renderer and templates for XML, JSON and TEXT were moved to the [Extended invoicing plugin](https://www.kimai.org/store/invoice-bundle.html) (install if you use one of those)
+- Moved `company.docx` to [external repo](https://github.com/kimai/invoice-templates/tree/main/docx-company) (needs to be re-uploaded if you want to keep on using it!)
+- Role names are forced to be uppercase 
+- Removed unused `public/avatars/` directory 
+- `local.yaml` is not compatible with old version, remove it before the update and then re-create it after everything works 
+  - dashboard default config
+  - removed: theme.branding.translation
+  - removed: kimai.plugin_dir
+- Time-tracking mode `duration_only` was removed, existing installations will be switched to `duration_fixed_begin`
+- Removed Twig filters. You might have to replace them in your custom export/invoice templates:
+  - `date_full` => `date_time`
+  - `duration_decimal` => `duration(true)`
+  - `currency` => `currency_name`
+  - `country` => `country_name`
+  - `language` => `language_name`
+- Removed support for custom translation files (use [TranslationBundle](https://www.kimai.org/store/translation-bundle.html) instead or write your own plugin)
+- Removed all 3rd party mailer packages, you need to install them manually (ONLY if you used a short syntax to configure the `MAILER_URL` in `.env`): 
+  - `composer require symfony/amazon-mailer`
+  - `composer require symfony/google-mailer`
+  - `composer require symfony/mailchimp-mailer`
+  - `composer require symfony/mailgun-mailer`

+If you are using MariaDB, it must be at least version 10.1, older versions are not supported any longer.
+
+**DEVELOPER**
+
+- Removed `formDateTime` field from API model `I18nConfig`
+- Upgraded to Doctrine DBAL 3, see [docs](https://github.com/doctrine/dbal/blob/3.1.x/UPGRADE.md) - you might have to update your bundle
+
+## [1.15](https://github.com/kimai/kimai/releases/tag/1.15)
+
+**Many database changes: don't forget to [run the updater](https://www.kimai.org/documentation/updates.html).**
+
+Updating the database might take quite a while, depending on the amount of timesheet entries and speed of your database server (~1 minute per 100k records).
+
+**ATTENTION**
+
+- This release bumps the minimum required [PHP version to 7.3](https://www.kimai.org/blog/2021/php8-support-php72-dropped/)
+- Self-registration is disabled by default
+- Self-registration now always requires email confirmation
+- All plugins that use own databases need to be updated as well
+- Removed the YearChart widget and the related configs named `userRecapThisYear`, `userRecapLastYear`, `userRecapTwoYears`, `userRecapThreeYears`
+
+**LDAP & SAML**
+
+Please verify your config with the [LDAP](https://www.kimai.org/documentation/ldap.html) and [SAML](https://www.kimai.org/documentation/saml.html) documentation, especially:
+
+- SAML users: activate it by setting the `kimai.saml.activate: true` config key
+- LDAP users: activate it by setting the `kimai.ldap.activate: true` config key
+- LDAP and SAML users need to remove the complete `security` section from their `local.yaml`
+
+**DEVELOPER**  
+
+PHP 8 compatibility forced to upgrade MANY libraries, including but not limited to:
+
+- Removed FOSUserBundle and hslavich/oneloginsaml
+- Doctrine Migrations, whose new major version forces plugin updates 
+- Gedmo v3 (which include BC breaks in definitions)
+- Doctrine DBAL and others, which required PHP 7.3 as well
+
+**API BC break**: Due to team structure changes, it was impossible to keep the (writing) API structure. Please adjust your code accordingly!
+
+## [1.14](https://github.com/kimai/kimai/releases/tag/1.14)
+
+**CRITICAL BC break**: SQLite support was removed. If you are using SQLite, you have to [read this blog post](https://www.kimai.org/blog/2021/sqlite-and-ftp-support-removed/) and migrate to MySQL/MariaDB first!
+
+**New database tables and fields: don't forget to [run the updater](https://www.kimai.org/documentation/updates.html).**
+
+Permission changes:
+- `history_invoice` - removed permission entirely
+
+## [1.13](https://github.com/kimai/kimai/releases/tag/1.13)
+
+- Deprecated `now` variable in export templates: create it yourself with `{% set now = create_date('now', app.user) %}`
+- Changed invoice filename generation (check if you use cronjob for invoices)

+
+## [1.12](https://github.com/kimai/kimai/releases/tag/1.12)
+
+- Export templates can now include items from plugins (eg. Expenses).
+
+## [1.10](https://github.com/kimai/kimai/releases/tag/1.10)

+- Sessions are now stored in the database (all users have to re-login after upgrade)
+- New permissions: `lockdown_grace_timesheet`, `lockdown_override_timesheet`, `view_all_data`
+- Fixed team permissions on user queries: depending on your previous team & permission setup your users might see less data (SUPER_ADMINS see all data, but new: ADMINS only see all data if they own the `view_all_data` permission)
+- Markdown does not support headings anymore, text like `# foo` is not converted to `<h1 id="foo">foo</h1>` anymore
+
+### Developer
+
+- **BC break**: removed registration of `.env` with `putenv()` - do not rely on `getenv()` as it is not thread-safe
+- **BC break**: interface method signature `HtmlToPdfConverter::convertToPdf()` changed
+- **BC break**: the macros `badge` and `label` do not apply the `|trans` filter any more
+- **BC Break**: removed `getVisible()` (deprecated since 1.4) method on Customer, Project and Activity (use `isVisible()` instead, templates are still working)
+- **BC Break**: API changes
+    - some representation names changed (eg. from `ActivityMetaField` to `ActivityMeta`, `TimesheetSubCollection` vs `TimesheetCollectionExpanded`), you could use `class_alias()` if you use auto-generated code from Swagger-Gen or alike
+    - new result types were introduced
+    - result data changed in some areas to smooth out inconsistencies (eg. TeamEntity fields changed in nested results)
+
+## [1.9](https://github.com/kimai/kimai/releases/tag/1.9)
+
+**New database tables and fields were created, don't forget to [run the updater](https://www.kimai.org/documentation/updates.html).**
+
+- The directory `var/data/invoices/` will be used to store archived invoice files (check file permissions)
+- The default invoice number format changed. If you want to use the old one: configure `{date}` as format - see [invoice documentation](https://www.kimai.org/documentation/invoices.html)
+- HTML invoice templates are now treated like other files and offered as download. If you are using relative URLs for including assets (CSS, images) you need to either inline them (see the default templates) or use absolute URLs
+- Invoice templates that use the templates variables `${activity.X}` or `${project.X}` should be checked and possibly adapted, as multi-select is now possible for filtering
+- Invoice templates have access to all meta-fields as variables, not only the ones marked as visible
+- Rates configuration/structure changed for customer, project and activity 
+  - **Invoice templates**: rates variables were removed
+
+Permission changes:
+- `history_invoice` - NEW: grants all features for the new invoice archive (by default for all admins)
+
+### Developer
+
+- **BC break**: `InvoiceItemInterface` has new methods `getType()` and `getCategory()`
+- **BC break**: API fields changed - see new `/rates` endpoints
+
+## [1.8](https://github.com/kimai/kimai/releases/tag/1.8)
+
+**New database tables and fields were created, don't forget to [run the updater](https://www.kimai.org/documentation/updates.html).**
+
+- New PHP requirement: `ext-xsl` - which should be pre-installed in most environments when `ext-xml` is loaded
+- New mailer library: check if emails are still working (eg. by using the "password forgotten" function) or if you need to adjust your configuration, [see docs at symfony.com](https://symfony.com/doc/current/components/mailer.html#transport)
+- Support for line breaks in multiline invoice fields for spreadsheets (check your invoice templates after the update) 
+
+Permission changes:
+
+- `comments_create_customer` - NEW: permission that allows to add new comments for customers  
+- `comments_create_team_customer` - NEW: permission that allows to add new comments for team members of the current customer 
+- `comments_create_teamlead_customer` - NEW: permission that allows to add new comments for a teamlead of the current customer 
+- `comments_create_project` - NEW: permission that allows to add new comments for project  
+- `comments_create_team_project` - NEW: permission that allows to add new comments for team members of the current project 
+- `comments_create_teamlead_project` - NEW: permission that allows to add new comments for a teamlead of the current project

+- `edit_teamlead_customer` - removed default permission from ROLE_TEAMLEAD (if you use it: change it in the Role & Permission UI) 
+- `upload_invoice_template` - NEW: permission that allows to upload invoice documents from the UI
+
+## [1.7](https://github.com/kimai/kimai/releases/tag/1.7)
+
+**New database tables and fields were created, don't forget to [run the updater](https://www.kimai.org/documentation/updates.html).**
+
+New permissions:
+
+- `comments_customer` - show comment list on customer detail page (new feature) 
+- `details_customer` - show detail information for customers (customer number, vat, rates, meta-fields, assigned teams ...)
+- `comments_project` - show comment list on project detail page (new feature) 
+- `details_project` - show detail information for projects (rates, meta-fields, assigned teams ...)
+
+If you are using teams, please read on: The following list of permissions are now also available in the UI and they (can) replace the `X_project` and `X_customer` permissions. 
+They are more strict, as they allow only access to team specific items, the older permissions without `_teamlead_`/`_team_` work on a global level instead.
+  
+- `view_teamlead_customer`, `edit_teamlead_customer`, `budget_teamlead_customer`, `permissions_teamlead_customer`, `comments_teamlead_customer`, `details_teamlead_customer` - allows access to customer data when user is teamlead of a team assigned to the customer (replaces more global permission like `view_customer` for teamleads)
+- `view_team_customer`, `edit_team_customer`, `budget_team_customer`, `comments_team_customer`, `details_team_customer` - allows access to customer data when user is member of a team assigned to the customer (replaces more global permission like `view_customer` for users)
+- `view_teamlead_project`, `edit_teamlead_project`, `budget_teamlead_project`, `permissions_teamlead_project`, `comments_teamlead_project`, `details_teamlead_project` - allows access to customer data when user is teamlead of a team assigned to the project (replaces more global permission like `view_project` for teamleads)
+- `view_team_project`, `edit_team_project`, `budget_team_project`, `comments_team_project`, `details_team_project` - allows access to customer data when user is member of a team assigned to the project (replaces more global permission like `view_project` for users)
+
+### ExpenseBundle
+
+**ATTENTION** due to incompatibilities in the underlying frameworks users of the ExpenseBundle need to do one more step:
+You need to delete the bundle before updating: `rm -r var/plugins/ExpenseBundle`, otherwise you will run into errors during the update.
+After the Kimai update was successful, you have to re-install the latest bundle version, which is compatible with Kimai 1.7 only. 
+
+### Developer
+
+- Projects now have a start and end date and the API will only return those, which are either unconfigured or currently active, you might want to reload the list of projects once the user entered begin and end datetime OR use the new `ignoreDates` parameter.
+- Doctrine bundle was updated to v2, check your code for [the usage of RegistryInterface and ObjectManager](https://github.com/doctrine/DoctrineBundle/blob/master/UPGRADE-2.0.md)
+- Removed the webserver bundle and the command `server:run` - see [docs](https://www.kimai.org/documentation/developers.html)
+
+## [1.6](https://github.com/kimai/kimai/releases/tag/1.6), [1.6.1](https://github.com/kimai/kimai/releases/tag/1.6.1), [1.6.2](https://github.com/kimai/kimai/releases/tag/1.6.2)
+
+**New database tables and fields were created, don't forget to [run the updater](https://www.kimai.org/documentation/updates.html).**
+
+- Invoice changes:
+  - Moved CSV, ODS and XSLX invoice templates to [another repository](https://github.com/Keleo/kimai2-invoice-templates). Using them? Install them manually (see [invoice documentation](https://www.kimai.org/documentation/invoices.html)).
+  - Added new invoice fields (VAT, contact, payment details) and customer field (VAT). Used the twig settings before? Move them to the respective invoice template settings.
+- Permissions can be managed via Admin UI. Please move your permission settings from [local.yaml to your database](https://www.kimai.org/documentation/permissions.html).
+- Important permission change: regular users with the `view_other_timesheet` permission could see all timesheets. This was a legacy from the time before team permissions were introduced. If you rely on this behavior, you need to create a team with all users and the teamlead being the user who needs access to all timesheets. 
+
+### Developer
+
+Please add default permissions to your [plugin](https://www.kimai.org/documentation/plugins.html).
+
+## [1.5](https://github.com/kimai/kimai/releases/tag/1.5)
+
+[Update as usual](https://www.kimai.org/documentation/updates.html)
+
+## [1.4](https://github.com/kimai/kimai/releases/tag/1.4)
+
+**There is a new directory, which needs to be writable by the webserver: `public/avatars/`.**
+
+New permission (used in new dashboard widget):
+- `view_team_member` - display team assignments (names, teamleads and members) for the current user
+
+Activated Javascript select component by default (check mobile devices).
+
+### Developer: BC breaks
+
+- Dashboard widgets and rows need to define their `type` by FQCN
+- Switched to Symfony 4.3 event types, this could fail in plugins, but only if they didn't use the official constants for event names
+
+## [1.3](https://github.com/kimai/kimai/releases/tag/1.3)
+
+Added `manage_tag` permission for new tag features
+
+### Developer: BC breaks
+
+- Refactored toolbars and search, plugins needs to be checked 
+- Invoices now supports multiple repositories, some method signatures had to be changed (eg. `calculateSumIdentifier()`)  
+
+## [1.2](https://github.com/kimai/kimai/releases/tag/1.2)
+
+**If you are still using 0.7 or below, you need to upgrade to 1.1 before upgrading to this version.**
+
+- Deleted timezone conversion command. 
+- Minimum password length raised from 5 to 8 character (applies only for password changes and new users)
+- Maximum customer name length lowered to 150 character
+- Maximum project name length lowered to 150 character
+- Maximum activity name length lowered to 150 character
+- Added new permission: `manage_invoice_template`
+  - Removed permissions: `view_invoice_template`, `create_invoice_template`, `edit_invoice_template`, `delete_invoice_template`
+- Removed permission: `view_export` (using `create_export` only)
+
+### Developer: BC breaks
+
+- Custom export renderer need to check for usage of `Timesheet::getEnd()` as running entries can now be exported as well
+
+## [1.1](https://github.com/kimai/kimai/releases/tag/1.1)
+
+[Update as usual](https://www.kimai.org/documentation/updates.html), nothing special for this release if you upgrade from 1.0 / 1.0.1.
+
+## [1.0](https://github.com/kimai/kimai/releases/tag/1.0)
+
+This release contains several changes, as I still have the goal to stabilize the code base to prevent 
+such "challenges" after 1.0 for a while.
+
+### Changes for your local.yaml
+ 
+New permissions are available. You have to add them to your `local.yaml` ONLY if you use a custom permission structure, 
+otherwise you can't use the new features: 
+- `view_tag` - view all tags
+- `delete_tag` - delete tags
+- `edit_exported_timesheet` - allows to edit records which were exported
+- `role_permissions` - view calculated permissions for user roles
+- `budget_activity` - view and edit budgets for activities
+- `budget_project` - view and edit budgets for projects
+- `budget_customer` - view and edit budgets for customers
+
+Removed permission:
+- `system_actions` - removed experimental feature to flush app cache from the about screen
+
+### BC BREAKS
+
+- API: Format for queries including a datetime object fixed to use HTML5 format (previously `2019-03-02 14:23` - now `2019-03-02T14:23:00`)
+- **Permission config**: the `permissions` definition in your `local.yaml` needs to be verified/changed, as the internal structure was highly optimized to simplify the definition. 
+Thanks to the new structure, you should be able to remove almost everything from your `local.yaml` (tip: start over from scratch!). Please read [the updated permission docu](https://www.kimai.org/documentation/permissions.html). 
+- default widgets were removed from `kimai.yaml`, that shouldn't cause any issues ... but if something is odd: [look here for help](https://www.kimai.org/documentation/dashboard.html)
+
+## [0.9](https://github.com/kimai/kimai/releases/tag/0.9)
+
+Remember to execute the necessary timezone conversion script, if you haven't updated to 0.8 before (see below)!
+
+### BC BREAKS
+
+This release contains some BC breaks which were necessary before 1.0 will be released (_now or never_), to prevent those BC breaks after 1.0. 
+
+- **Kimai requires PHP 7.2 now => [PHP 7.1 expired 4 month ago](https://www.php.net/supported-versions.php)**
+- The `.env` variable `DATABASE_PREFIX` was removed and the table prefix is now hardcoded to `kimai2_`. If you used another prefix, 
+you have to rename your tables manually before starting the update process. You can delete the row `DATABASE_PREFIX` from your `.env` file.
+- API: Format for DateTime objects changed, now including timezone identifier (previously `2019-03-02 14:23` - now `2019-03-02T14:23:00+00:00`), see [#718](https://github.com/kimai/kimai/pull/718)
+- API: changed from snake_case to camelCase (affected fields: hourlyRate vs hourly_rate / fixedRate vs fixed_rate / orderNumber vs order_number / i18n config object)
+- Plugin mechanism changed: existing Plugins have to be deleted or updated
+
+### Apply necessary changes to your `local.yaml`: 
+
+New permissions are available: 
+- `system_configuration` - for accessing the new system configuration screen
+- `system_actions` - for the experimental feature to flush your cache from the about screen
+- `plugins` - for accessing the new plugins screen
+
+The setting `kimai.timesheet.mode` replaces the setting `kimai.timesheet.duration_only`. If you used the duration_only mode, you need to change your config:
+```yaml
+# Before
+kimai:
+    timesheet:
+        duration_only: true
+        
+# After
+kimai:
+    timesheet:
+        mode: duration_only
+```
+Or switch the mode directly in the new System configuration screen within Kimai.  
+
+## [0.8.1](https://github.com/kimai/kimai/releases/tag/0.8.1)
+
+A bug fixing release. Remember to execute the necessary timezone conversion script, if you haven't updated to 0.8 before (see below)!
+
+## [0.8](https://github.com/kimai/kimai/releases/tag/0.8)
+
+After you followed the normal update and database migration process (see above), you need to execute a bash command to convert your timesheet data for timezone support:
+
+- Read this [pull request](https://github.com/kimai/kimai/pull/372) BEFORE you follow the instructions to convert the 
+timezones in your existing time records with `bin/console kimai:convert-timezone`. Without that, you will end up with wrong times in your database.
+
+### Apply necessary changes to your `local.yaml`: 
+
+- A new boolean setting `kimai.timesheet.rules.allow_future_times` was introduced
+- New permissions are available: 
+  - `view_export` - for the new export feature
+  - `create_export` - for the new export feature
+  - `edit_export_own_timesheet` - for the new export feature
+  - `edit_export_other_timesheet` - for the new export feature
+  - `system_information` - to see the new about screen
+
+## [0.7](https://github.com/kimai/kimai/releases/tag/0.7)
+
+The configuration `kimai.theme.active_warning` was deprecated and should be replaced in your local.yaml, 
+[read config docs for more information](https://www.kimai.org/documentation/timesheet.html#limit-active-entries).
+
+## [0.6.1](https://github.com/kimai/kimai/releases/tag/0.6.1)
+
+A bugfix release to address database compatibility issues with older MySQL/MariaDB versions.
+
+## [0.6](https://github.com/kimai/kimai/releases/tag/0.6)
+
+The API has some minor BC breaks: some fields were renamed and entities have a larger attribute set than collections. 
+Be aware that the API is still is development mode and shouldn't be considered stable for now.
+
+## [0.5](https://github.com/kimai/kimai/releases/tag/0.5)
+
+Some configuration nodes were removed, if you have one of them in your `local.yaml` you need to delete them before you start the update:
+- `kimai.invoice.calculator`
+- `kimai.invoice.renderer`
+- `kimai.invoice.number_generator`
+
+The new config `kimai.invoice.documents` was introduced, holding a list of directories ([read more](https://www.kimai.org/documentation/invoices.html)).
+
+**BC break:** InvoiceTemplate name was changed from 255 characters to 60. If you used longer invoice-template names, they will be truncated when upgrading the database.
+Please make sure that they are unique in the first 60 character before you upgrade your database with `doctrine:migrations:migrate`. 
+
+## [0.4](https://github.com/kimai/kimai/releases/tag/0.4)
+
+In the time between 0.3 and 0.4 there was a release of composer that introduced a BC break, 
+which leads to problems between Composer and Symfony Flex, resulting in an error like this when running it:
+
+```
+  [ErrorException]
+  Declaration of Symfony\Flex\ParallelDownloader::getRemoteContents($originUrl, $fileUrl, $context) should be compatible with Composer\Util\RemoteFilesystem::getRemoteContents($originUrl, $fileUrl, $context, ?array &$responseHeaders = NULL)
+```
+
+This can be fixed by updating Composer and Flex before executing the Kimai update:
+```
+sudo composer self-update
+sudo -u www-data composer update symfony/flex --no-plugins --no-scripts
+```
+
+## [0.3](https://github.com/kimai/kimai/releases/tag/0.3)
+
+You need to adjust your `.env` file and add your `from` address for [all emails](https://www.kimai.org/documentation/emails.html) generated by Kimai 2:
+```
+MAILER_FROM=kimai@example.com
+```
+
+Create a file and database backup before executing the following steps: 
+
+```bash
+git pull origin master
+sudo -u www-data composer install --no-dev --optimize-autoloader
+sudo -u www-data bin/console cache:clear --env=prod
+sudo -u www-data bin/console cache:warmup --env=prod
+bin/console doctrine:migrations:version --add 20180701120000
+bin/console doctrine:migrations:migrate
+```
