+Using Creative Commons Public Licenses
+
+Creative Commons public licenses provide a standard set of terms and

+original works of authorship and other material subject to copyright
+and certain other rights specified in the public license below. The
+following considerations are for informational purposes only, are not

+
+     Considerations for licensors: Our public licenses are
+     intended for use by those authorized to give the public
+     permission to use material in ways otherwise restricted by
+     copyright and certain other rights. Our licenses are
+     irrevocable. Licensors should read and understand the terms

+     Licensors should also secure all rights necessary before

+
+By exercising the Licensed Rights (defined below), You accept and agree
+to be bound by the terms and conditions of this Creative Commons
+Attribution 4.0 International Public License ("Public License"). To the
+extent this Public License may be interpreted as a contract, You are
+granted the Licensed Rights in consideration of Your acceptance of
+these terms and conditions, and the Licensor grants You such rights in
+consideration of benefits the Licensor receives from making the
+Licensed Material available under these terms and conditions.
+
+
+Section 1 -- Definitions.
+
+  a. Adapted Material means material subject to Copyright and Similar
+     Rights that is derived from or based upon the Licensed Material
+     and in which the Licensed Material is translated, altered,
+     arranged, transformed, or otherwise modified in a manner requiring
+     permission under the Copyright and Similar Rights held by the
+     Licensor. For purposes of this Public License, where the Licensed
+     Material is a musical work, performance, or sound recording,
+     Adapted Material is always produced where the Licensed Material is
+     synched in timed relation with a moving image.
+
+  b. Adapter's License means the license You apply to Your Copyright
+     and Similar Rights in Your contributions to Adapted Material in
+     accordance with the terms and conditions of this Public License.
+
+  c. Copyright and Similar Rights means copyright and/or similar rights
+     closely related to copyright including, without limitation,
+     performance, broadcast, sound recording, and Sui Generis Database
+     Rights, without regard to how the rights are labeled or
+     categorized. For purposes of this Public License, the rights
+     specified in Section 2(b)(1)-(2) are not Copyright and Similar
+     Rights.
+
+  d. Effective Technological Measures means those measures that, in the
+     absence of proper authority, may not be circumvented under laws
+     fulfilling obligations under Article 11 of the WIPO Copyright
+     Treaty adopted on December 20, 1996, and/or similar international
+     agreements.
+
+  e. Exceptions and Limitations means fair use, fair dealing, and/or
+     any other exception or limitation to Copyright and Similar Rights
+     that applies to Your use of the Licensed Material.
+
+  f. Licensed Material means the artistic or literary work, database,
+     or other material to which the Licensor applied this Public
+     License.
+
+  g. Licensed Rights means the rights granted to You subject to the
+     terms and conditions of this Public License, which are limited to
+     all Copyright and Similar Rights that apply to Your use of the
+     Licensed Material and that the Licensor has authority to license.
+
+  h. Licensor means the individual(s) or entity(ies) granting rights
+     under this Public License.
+
+  i. Share means to provide material to the public by any means or
+     process that requires permission under the Licensed Rights, such
+     as reproduction, public display, public performance, distribution,
+     dissemination, communication, or importation, and to make material
+     available to the public including in ways that members of the
+     public may access the material from a place and at a time
+     individually chosen by them.
+
+  j. Sui Generis Database Rights means rights other than copyright
+     resulting from Directive 96/9/EC of the European Parliament and of
+     the Council of 11 March 1996 on the legal protection of databases,
+     as amended and/or succeeded, as well as other essentially
+     equivalent rights anywhere in the world.
+
+  k. You means the individual or entity exercising the Licensed Rights
+     under this Public License. Your has a corresponding meaning.
+
+
+Section 2 -- Scope.
+
+  a. License grant.
+
+       1. Subject to the terms and conditions of this Public License,
+          the Licensor hereby grants You a worldwide, royalty-free,
+          non-sublicensable, non-exclusive, irrevocable license to
+          exercise the Licensed Rights in the Licensed Material to:
+
+            a. reproduce and Share the Licensed Material, in whole or
+               in part; and
+
+            b. produce, reproduce, and Share Adapted Material.
+
+       2. Exceptions and Limitations. For the avoidance of doubt, where
+          Exceptions and Limitations apply to Your use, this Public
+          License does not apply, and You do not need to comply with
+          its terms and conditions.
+
+       3. Term. The term of this Public License is specified in Section
+          6(a).
+
+       4. Media and formats; technical modifications allowed. The
+          Licensor authorizes You to exercise the Licensed Rights in
+          all media and formats whether now known or hereafter created,
+          and to make technical modifications necessary to do so. The
+          Licensor waives and/or agrees not to assert any right or
+          authority to forbid You from making technical modifications
+          necessary to exercise the Licensed Rights, including
+          technical modifications necessary to circumvent Effective
+          Technological Measures. For purposes of this Public License,
+          simply making modifications authorized by this Section 2(a)
+          (4) never produces Adapted Material.
+
+       5. Downstream recipients.
+
+            a. Offer from the Licensor -- Licensed Material. Every
+               recipient of the Licensed Material automatically
+               receives an offer from the Licensor to exercise the
+               Licensed Rights under the terms and conditions of this
+               Public License.
+
+            b. No downstream restrictions. You may not offer or impose
+               any additional or different terms or conditions on, or
+               apply any Effective Technological Measures to, the
+               Licensed Material if doing so restricts exercise of the
+               Licensed Rights by any recipient of the Licensed
+               Material.
+
+       6. No endorsement. Nothing in this Public License constitutes or
+          may be construed as permission to assert or imply that You
+          are, or that Your use of the Licensed Material is, connected
+          with, or sponsored, endorsed, or granted official status by,
+          the Licensor or others designated to receive attribution as
+          provided in Section 3(a)(1)(A)(i).
+
+  b. Other rights.
+
+       1. Moral rights, such as the right of integrity, are not
+          licensed under this Public License, nor are publicity,
+          privacy, and/or other similar personality rights; however, to
+          the extent possible, the Licensor waives and/or agrees not to
+          assert any such rights held by the Licensor to the limited
+          extent necessary to allow You to exercise the Licensed
+          Rights, but not otherwise.
+
+       2. Patent and trademark rights are not licensed under this
+          Public License.
+
+       3. To the extent possible, the Licensor waives any right to
+          collect royalties from You for the exercise of the Licensed
+          Rights, whether directly or through a collecting society
+          under any voluntary or waivable statutory or compulsory
+          licensing scheme. In all other cases the Licensor expressly
+          reserves any right to collect such royalties.
+
+
+Section 3 -- License Conditions.
+
+Your exercise of the Licensed Rights is expressly made subject to the
+following conditions.
+
+  a. Attribution.
+
+       1. If You Share the Licensed Material (including in modified
+          form), You must:
+
+            a. retain the following if it is supplied by the Licensor
+               with the Licensed Material:
+
+                 i. identification of the creator(s) of the Licensed
+                    Material and any others designated to receive
+                    attribution, in any reasonable manner requested by
+                    the Licensor (including by pseudonym if
+                    designated);
+
+                ii. a copyright notice;
+
+               iii. a notice that refers to this Public License;
+
+                iv. a notice that refers to the disclaimer of
+                    warranties;
+
+                 v. a URI or hyperlink to the Licensed Material to the
+                    extent reasonably practicable;
+
+            b. indicate if You modified the Licensed Material and
+               retain an indication of any previous modifications; and
+
+            c. indicate the Licensed Material is licensed under this
+               Public License, and include the text of, or the URI or
+               hyperlink to, this Public License.
+
+       2. You may satisfy the conditions in Section 3(a)(1) in any
+          reasonable manner based on the medium, means, and context in
+          which You Share the Licensed Material. For example, it may be
+          reasonable to satisfy the conditions by providing a URI or
+          hyperlink to a resource that includes the required
+          information.
+
+       3. If requested by the Licensor, You must remove any of the
+          information required by Section 3(a)(1)(A) to the extent
+          reasonably practicable.
+
+       4. If You Share Adapted Material You produce, the Adapter's
+          License You apply must not prevent recipients of the Adapted
+          Material from complying with this Public License.
+
+
+Section 4 -- Sui Generis Database Rights.
+
+Where the Licensed Rights include Sui Generis Database Rights that
+apply to Your use of the Licensed Material:
+
+  a. for the avoidance of doubt, Section 2(a)(1) grants You the right
+     to extract, reuse, reproduce, and Share all or a substantial
+     portion of the contents of the database;
+
+  b. if You include all or a substantial portion of the database
+     contents in a database in which You have Sui Generis Database
+     Rights, then the database in which You have Sui Generis Database
+     Rights (but not its individual contents) is Adapted Material; and
+
+  c. You must comply with the conditions in Section 3(a) if You Share
+     all or a substantial portion of the contents of the database.
+
+For the avoidance of doubt, this Section 4 supplements and does not
+replace Your obligations under this Public License where the Licensed
+Rights include other Copyright and Similar Rights.
+
+
+Section 5 -- Disclaimer of Warranties and Limitation of Liability.
+
+  a. UNLESS OTHERWISE SEPARATELY UNDERTAKEN BY THE LICENSOR, TO THE
+     EXTENT POSSIBLE, THE LICENSOR OFFERS THE LICENSED MATERIAL AS-IS
+     AND AS-AVAILABLE, AND MAKES NO REPRESENTATIONS OR WARRANTIES OF
+     ANY KIND CONCERNING THE LICENSED MATERIAL, WHETHER EXPRESS,
+     IMPLIED, STATUTORY, OR OTHER. THIS INCLUDES, WITHOUT LIMITATION,
+     WARRANTIES OF TITLE, MERCHANTABILITY, FITNESS FOR A PARTICULAR
+     PURPOSE, NON-INFRINGEMENT, ABSENCE OF LATENT OR OTHER DEFECTS,
+     ACCURACY, OR THE PRESENCE OR ABSENCE OF ERRORS, WHETHER OR NOT
+     KNOWN OR DISCOVERABLE. WHERE DISCLAIMERS OF WARRANTIES ARE NOT
+     ALLOWED IN FULL OR IN PART, THIS DISCLAIMER MAY NOT APPLY TO YOU.
+
+  b. TO THE EXTENT POSSIBLE, IN NO EVENT WILL THE LICENSOR BE LIABLE
+     TO YOU ON ANY LEGAL THEORY (INCLUDING, WITHOUT LIMITATION,
+     NEGLIGENCE) OR OTHERWISE FOR ANY DIRECT, SPECIAL, INDIRECT,
+     INCIDENTAL, CONSEQUENTIAL, PUNITIVE, EXEMPLARY, OR OTHER LOSSES,
+     COSTS, EXPENSES, OR DAMAGES ARISING OUT OF THIS PUBLIC LICENSE OR
+     USE OF THE LICENSED MATERIAL, EVEN IF THE LICENSOR HAS BEEN
+     ADVISED OF THE POSSIBILITY OF SUCH LOSSES, COSTS, EXPENSES, OR
+     DAMAGES. WHERE A LIMITATION OF LIABILITY IS NOT ALLOWED IN FULL OR
+     IN PART, THIS LIMITATION MAY NOT APPLY TO YOU.
+
+  c. The disclaimer of warranties and limitation of liability provided
+     above shall be interpreted in a manner that, to the extent
+     possible, most closely approximates an absolute disclaimer and
+     waiver of all liability.
+
+
+Section 6 -- Term and Termination.
+
+  a. This Public License applies for the term of the Copyright and
+     Similar Rights licensed here. However, if You fail to comply with
+     this Public License, then Your rights under this Public License
+     terminate automatically.
+
+  b. Where Your right to use the Licensed Material has terminated under
+     Section 6(a), it reinstates:
+
+       1. automatically as of the date the violation is cured, provided
+          it is cured within 30 days of Your discovery of the
+          violation; or
+
+       2. upon express reinstatement by the Licensor.
+
+     For the avoidance of doubt, this Section 6(b) does not affect any
+     right the Licensor may have to seek remedies for Your violations
+     of this Public License.
+
+  c. For the avoidance of doubt, the Licensor may also offer the
+     Licensed Material under separate terms or conditions or stop
+     distributing the Licensed Material at any time; however, doing so
+     will not terminate this Public License.
+
+  d. Sections 1, 5, 6, 7, and 8 survive termination of this Public
+     License.
+
+
+Section 7 -- Other Terms and Conditions.
+
+  a. The Licensor shall not be bound by any additional or different
+     terms or conditions communicated by You unless expressly agreed.
+
+  b. Any arrangements, understandings, or agreements regarding the
+     Licensed Material not stated herein are separate from and
+     independent of the terms and conditions of this Public License.
+
+
+Section 8 -- Interpretation.
+
+  a. For the avoidance of doubt, this Public License does not, and
+     shall not be interpreted to, reduce, limit, restrict, or impose
+     conditions on any use of the Licensed Material that could lawfully
+     be made without permission under this Public License.
+
+  b. To the extent possible, if any provision of this Public License is
+     deemed unenforceable, it shall be automatically reformed to the
+     minimum extent necessary to make it enforceable. If the provision
+     cannot be reformed, it shall be severed from this Public License
+     without affecting the enforceability of the remaining terms and
+     conditions.
+
+  c. No term or condition of this Public License will be waived and no
+     failure to comply consented to unless expressly agreed to by the
+     Licensor.
+
+  d. Nothing in this Public License constitutes or may be interpreted
+     as a limitation upon, or waiver of, any privileges and immunities
+     that apply to the Licensor or You, including from the legal
+     processes of any jurisdiction or authority.

-## [unreleased]
+## Unreleased
+
+### Added
+- Experimental websocket-based federation between Pleroma instances.
 
 ### Changed
+
+- Renamed `:await_up_timeout` in `:connections_pool` namespace to `:connect_timeout`, old name is deprecated.
+- Renamed `:timeout` in `pools` namespace to `:recv_timeout`, old name is deprecated.
+- The `discoverable` field in the `User` struct will now add a NOINDEX metatag to profile pages when false.
+- Users with the `discoverable` field set to false will not show up in searches.
+- Minimum lifetime for ephmeral activities changed to 10 minutes and made configurable (`:min_lifetime` option).
+
+### Added
+- Media preview proxy (requires media proxy be enabled; see `:media_preview_proxy` config for more details).
+- Pleroma API: Importing the mutes users from CSV files.
+
+### Removed
+
+- **Breaking:** `Pleroma.Workers.Cron.StatsWorker` setting from Oban `:crontab` (moved to a simpler implementation).
+- **Breaking:** `Pleroma.Workers.Cron.ClearOauthTokenWorker` setting from Oban `:crontab` (moved to scheduled jobs).
+- **Breaking:** `Pleroma.Workers.Cron.PurgeExpiredActivitiesWorker` setting from Oban `:crontab` (moved to scheduled jobs).
+- Removed `:managed_config` option. In practice, it was accidentally removed with 2.0.0 release when frontends were
+switched to a new configuration mechanism, however it was not officially removed until now.
+
+
+## [2.1.2] - 2020-09-17
+
+### Security
+
+- Fix most MRF rules either crashing or not being applied to objects passed into the Common Pipeline (ChatMessage, Question, Answer, Audio, Event).
+
+### Fixed
+
+- Welcome Chat messages preventing user registration with MRF Simple Policy applied to the local instance.
+- Mastodon API: the public timeline returning an error when the `reply_visibility` parameter is set to `self` for an unauthenticated user.
+- Mastodon Streaming API: Handler crashes on authentication failures, resulting in error logs.
+- Mastodon Streaming API: Error logs on client pings.
+- Rich media: Log spam on failures. Now the error is only logged once per attempt.
+
+### Changed
+
+- Rich Media: A HEAD request is now done to the url, to ensure it has the appropriate content type and size before proceeding with a GET.
+
+### Upgrade notes
+
+1. Restart Pleroma
+
+## [2.1.1] - 2020-09-08
+
+### Security
+- Fix possible DoS in Mastodon API user search due to an error in match clauses, leading to an infinite recursion and subsequent OOM with certain inputs.
+- Fix metadata leak for accounts and statuses on private instances.
+- Fix possible DoS in Admin API search using an atom leak vulnerability. Authentication with admin rights was required to exploit.
+
+### Changed
+
+- **Breaking:** The metadata providers RelMe and Feed are no longer configurable. RelMe should always be activated and Feed only provides a <link> header tag for the actual RSS/Atom feed when the instance is public.
+- Improved error message when cmake is not available at build stage.
+
+### Added
+- Rich media failure tracking (along with `:failure_backoff` option).
+
+<details>
+  <summary>Admin API Changes</summary>
+
+- Add `PATCH /api/pleroma/admin/instance_document/:document_name` to modify the Terms of Service and Instance Panel HTML pages via Admin API
+</details>
+
+### Fixed
+- Default HTTP adapter not respecting pool setting, leading to possible OOM.
+- Fixed uploading webp images when the Exiftool Upload Filter is enabled by skipping them
+- Mastodon API: Search parameter `following` now correctly returns the followings rather than the followers
+- Mastodon API: Timelines hanging for (`number of posts with links * rich media timeout`) in the worst case.
+  Reduced to just rich media timeout.
+- Mastodon API: Cards being wrong for preview statuses due to cache key collision.
+- Password resets no longer processed for deactivated accounts.
+- Favicon scraper raising exceptions on URLs longer than 255 characters.
+
+## [2.1.0] - 2020-08-28
+
+### Changed
+
 - **Breaking:** The default descriptions on uploads are now empty. The old behavior (filename as default) can be configured, see the cheat sheet.
 - **Breaking:** Added the ObjectAgePolicy to the default set of MRFs. This will delist and strip the follower collection of any message received that is older than 7 days. This will stop users from seeing very old messages in the timelines. The messages can still be viewed on the user's page and in conversations. They also still trigger notifications.
 - **Breaking:** Elixir >=1.9 is now required (was >= 1.8)
 - **Breaking:** Configuration: `:auto_linker, :opts` moved to `:pleroma, Pleroma.Formatter`. Old config namespace is deprecated.
+- **Breaking:** Configuration: `:instance, welcome_user_nickname` moved to `:welcome, :direct_message, :sender_nickname`, `:instance, :welcome_message` moved to `:welcome, :direct_message, :message`. Old config namespace is deprecated.
+- **Breaking:** LDAP: Fallback to local database authentication has been removed for security reasons and lack of a mechanism to ensure the passwords are synchronized when LDAP passwords are updated.
+- **Breaking** Changed defaults for `:restrict_unauthenticated` so that when `:instance, :public` is set to `false` then all `:restrict_unauthenticated` items be effectively set to `true`. If you'd like to allow unauthenticated access to specific API endpoints on a private instance, please explicitly set `:restrict_unauthenticated` to non-default value in `config/prod.secret.exs`.
 - In Conversations, return only direct messages as `last_status`
 - Using the `only_media` filter on timelines will now exclude reblog media
 - MFR policy to set global expiration for all local Create activities
 - OGP rich media parser merged with TwitterCard
 - Configuration: `:instance, rewrite_policy` moved to `:mrf, policies`, `:instance, :mrf_transparency` moved to `:mrf, :transparency`, `:instance, :mrf_transparency_exclusions` moved to `:mrf, :transparency_exclusions`. Old config namespace is deprecated.
 - Configuration: `:media_proxy, whitelist` format changed to host with scheme (e.g. `http://example.com` instead of `example.com`). Domain format is deprecated.
-- **Breaking:** Configuration: `:instance, welcome_user_nickname` moved to `:welcome, :direct_message, :sender_nickname`, `:instance, :welcome_message` moved to `:welcome, :direct_message, :message`. Old config namespace is deprecated.

+
+`mix pleroma.frontend install <frontend> [--ref <ref>] [--file <file>] [--build-url <build-url>] [--path <path>] [--build-dir <build-dir>]`
+
+Frontend can be installed either from local zip file, or automatically downloaded from the web.
+
+You can give all the options directly on the command like, but missing information will be filled out by looking at the data configured under `frontends.available` in the config files.
+
+Currently known `<frontend>` values are:
+- [admin-fe](https://git.pleroma.social/pleroma/admin-fe)
+- [kenoma](http://git.pleroma.social/lambadalambda/kenoma)
+- [pleroma-fe](http://git.pleroma.social/pleroma/pleroma-fe)
+- [fedi-fe](https://git.pleroma.social/pleroma/fedi-fe)
+- [soapbox-fe](https://gitlab.com/soapbox-pub/soapbox-fe)
+
+You can still install frontends that are not configured, see below.
+
+## Example installations for a known frontend
+
+For a frontend configured under the `available` key, it's enough to install it by name.
+
+```sh tab="OTP"
+./bin/pleroma_ctl frontend install pleroma
+```
+
+```sh tab="From Source"
+mix pleroma.frontend install pleroma
+```
+
+This will download the latest build for the the pre-configured `ref` and install it. It can then be configured as the one of the served frontends in the config file (see `primary` or `admin`).
+
+You can override any of the details. To install a pleroma build from a different url, you could do this:
+
+```sh tab="OPT"
+./bin/pleroma_ctl frontend install pleroma --ref 2hu_edition --build-url https://example.org/raymoo.zip
+```
+
+```sh tab="From Source"
+mix pleroma.frontend install pleroma --ref 2hu_edition --build-url https://example.org/raymoo.zip
+```
+
+Similarly, you can also install from a local zip file.
+
+```sh tab="OTP"
+./bin/pleroma_ctl frontend install pleroma --ref mybuild --file ~/Downloads/doomfe.zip
+```
+
+```sh tab="From Source"
+mix pleroma.frontend install pleroma --ref mybuild --file ~/Downloads/doomfe.zip
+```
+
+The resulting frontend will always be installed into a folder of this template: `${instance_static}/frontends/${name}/${ref}`
+
+Careful: This folder will be completely replaced on installation
+
+## Example installation for an unknown frontend
+
+The installation process is the same, but you will have to give all the needed options on the commond line. For example:
+
+```sh tab="OTP"
+./bin/pleroma_ctl frontend install gensokyo --ref master --build-url https://gensokyo.2hu/builds/marisa.zip
+```
+
+```sh tab="From Source"
+mix pleroma.frontend install gensokyo --ref master --build-url https://gensokyo.2hu/builds/marisa.zip
+```
+
+If you don't have a zip file but just want to install a frontend from a local path, you can simply copy the files over a folder of this template: `${instance_static}/frontends/${name}/${ref}`
+
