-## UNRELEASED
-
-## BREAKING
-- Minimum PostgreSQL version is raised to 12
-- Swagger UI moved from `/akkoma/swaggerui/` to `/pleroma/swaggerui/`
-
-## Added
-- Implement [FEP-67ff](https://codeberg.org/fediverse/fep/src/branch/main/fep/67ff/fep-67ff.md) (federation documentation)
-- Meilisearch: it is now possible to use separate keys for search and admin actions
-- New standalone `prune_orphaned_activities` mix task with configurable batch limit
-- The `prune_objects` mix task now accepts a `--limit` parameter for initial object pruning
-
-## Fixed
-- Meilisearch: order of results returned from our REST API now actually matches how Meilisearch ranks results
-- Emoji are now federated as anonymous objects, fixing issues with
-  some strict servers e.g. rejecting e.g. remote emoji reactions
-- AP objects with additional JSON-LD profiles beyond ActivityStreams can now be fetched
-- Single-selection polls no longer expose the voter_count; MastoAPI demands it be null
-  and this confused some clients leading to vote distributions >100%
-
-## Changed
-- Refactored Rich Media to cache the content in the database. Fetching operations that could block status rendering have been eliminated.
-
-## 2024.04.1 (Security)
-
-## Fixed
-- Issue allowing non-owners to use media objects in posts
-- Issue allowing use of non-media objects as attachments and crashing timeline rendering
-- Issue allowing webfinger spoofing in certain situations
-
-## 2024.04
-
-## Added
-- Support for [FEP-fffd](https://codeberg.org/fediverse/fep/src/branch/main/fep/fffd/fep-fffd.md) (proxy objects)
-- Verified support for elixir 1.16
-- Uploadfilter `Pleroma.Upload.Filter.Exiftool.ReadDescription` returns description values to the FE so they can pre fill the image description field
-  NOTE: this filter MUST be placed before `Exiftool.StripMetadata` to work
-
-## Changed
-- Inbound pipeline error handing was modified somewhat, which should lead to less incomprehensible log spam. Hopefully.
-- Uploadfilter `Pleroma.Upload.Filter.Exiftool` was replaced by `Pleroma.Upload.Filter.Exiftool.StripMetadata`;
-  the latter strips all non-essential metadata by default but can be configured.
-  To regain the old behaviour of only stripping GPS data set `purge: ["gps:all"]`.
-- Uploadfilter `Pleroma.Upload.Filter.Exiftool` has been renamed to `Pleroma.Upload.Filter.Exiftool.StripMetadata`
-- MRF.InlineQuotePolicy now prefers to insert display URLs instead of ActivityPub IDs
-- Old accounts are no longer listed in WebFinger as aliases; this was breaking spec
-
-## Fixed
-- Issue preventing fetching anything from IPv6-only instances
-- Issue allowing post content to leak via opengraph tags despite :estrict\_unauthenticated being set
-- Move activities no longer operate on stale user data
-- Missing definitions in our JSON-LD context
-- Issue mangling newlines in code blocks for RSS/Atom feeds
-- static\_fe squeezing non-square avatars and emoji
-- Issue leading to properly JSON-LD compacted emoji reactions being rejected
-- We now use a standard-compliant Accept header when fetching ActivityPub objects
-- /api/pleroma/notification\_settings was rejecting body parameters;
-  this also broke changing this setting via akkoma-fe
-- Issue leading to Mastodon bot accounts being rejected
-- Scope misdetection of remote posts resulting from not recognising
-  JSON-LD-compacted forms of public scope; affected e.g. federation with bovine
-- Ratelimits encountered when fetching objects are now respected; 429 responses will cause a backoff when we get one.
-
-## Removed
-- ActivityPub Client-To-Server write API endpoints have been disabled;
-  read endpoints are planned to be removed next release unless a clear need is demonstrated
-
-## 2024.03
-
-## Added
-- CLI tasks best-effort checking for past abuse of the recent spoofing exploit
-- new `:mrf_steal_emoji, :download_unknown_size` option; defaults to `false`
-
-## Changed
-- `Pleroma.Upload, :base_url` now MUST be configured explicitly if used;
-  use of the same domain as the instance is **strongly** discouraged
-- `:media_proxy, :base_url` now MUST be configured explicitly if used;
-  use of the same domain as the instance is **strongly** discouraged
-- StealEmoji:
-  - now uses the pack.json format;
-    existing users must migrate with an out-of-band script (check release notes)
-  - only steals shortcodes recognised as valid
-  - URLs of stolen emoji is no longer predictable
-- The `Dedupe` upload filter is now always active;
-  `AnonymizeFilenames` is again opt-in
-- received AP data is sanity checked before we attempt to parse it as a user
-- Uploads, emoji and media proxy now restrict Content-Type headers to a safe subset
-- Akkoma will no longer fetch and parse objects hosted on the same domain
-
-## Fixed
-- Critical security issue allowing Akkoma to be used as a vector for
-  (depending on configuration) impersonation of other users or creation
-  of bogus users and posts on the upload domain
-- Critical security issue letting Akkoma fall for the above impersonation
-  payloads due to lack of strict id checking
-- Critical security issue allowing domains redirect to to pose as the initial domain
-  (e.g. with media proxy's fallback redirects)
-- refetched objects can no longer attribute themselves to third-party actors
-  (this had no externally visible effect since actor info is read from the Create activity)
-- our litepub JSON-LD schema is now served with the correct content type
-- remote APNG attachments are now recognised as images
-
-## Upgrade Notes
-
-- As mentioned in "Changed", `Pleroma.Upload, :base_url` **MUST** be configured. Uploads will fail without it.
-  - Akkoma will refuse to start if this is not set.
-- Same with media proxy.
-
-## 2024.02
+## Unreleased
 
 ## Added
 - Full compatibility with Erlang OTP26
 - handling of GET /api/v1/preferences
-- Akkoma API is now documented
-- ability to auto-approve follow requests from users you are already following
-- The SimplePolicy MRF can now strip user backgrounds from selected remote hosts
+- Explicit listing of config keys that are allowed to be set by the database
+  - Previously set config keys will still be loaded, but you will get a warning
+    that they probably should not be dynamically configured.
 
 ## Changed
 - OTP builds are now built on erlang OTP26
 - The base Phoenix framework is now updated to 1.7
-- An `outbox` field has been added to actor profiles to comply with AP spec
-- User profile backgrounds do now federate with other Akkoma instances and Sharkey
 
 ## Fixed
 - Documentation issue in which a non-existing nginx file was referenced
 - Issue where a bad inbox URL could break federation
-- Issue where hashtag rel values would be scrubbed
-- Issue where short domains listed in `transparency_obfuscate_domains` were not actually obfuscated

-
-Akkoma mostly follows the server-to-server parts of the ActivityPub standard,
-but implements quirks for Mastodon compatibility as well as Mastodon-specific
-and custom extensions.
-
-See our documentation and Mastodon’s federation information
-linked further below for details on these quirks and extensions.
-
-Akkoma does not perform JSON-LD processing.

-#### HTTP Signatures
-All AP S2S POST requests to Akkoma instances MUST be signed.
-Depending on instance configuration the same may be true for GET requests.

-## Nodeinfo
-
-Akkoma provides many additional entries in its nodeinfo response,
-see the documentation linked below for details.

It also wont delete posts when at least one of the posts in that thread is kept (e.g. because one of the posts has seen recent activity).
 - `--keep-non-public` - Keep non-public posts like DM's and followers-only, even if they are remote.
-- `--limit` - limits how many remote posts get pruned. This limit does **not** apply to any of the follow up jobs. If wanting to keep the database load in check it is thus advisable to run the standalone `prune_orphaned_activities` task with a limit afterwards instead of passing `--prune-orphaned-activities` to this task.
 - `--prune-orphaned-activities` - Also prune orphaned activities afterwards. Activities are things like Like, Create, Announce, Flag (aka reports)... They can significantly help reduce the database size.

+## Disable generic query plans
+
+When PostgreSQL receives a query, it decides on a strategy for searching the requested data, this is called a query plan. The query planner has two modes: generic and custom. Generic makes a plan for all queries of the same shape, ignoring the parameters, which is then cached and reused. Custom, on the contrary, generates a unique query plan based on query parameters.
+
+By default PostgreSQL has an algorithm to decide which mode is more efficient for particular query, however this algorithm has been observed to be wrong on some of the queries Akkoma sends, leading to serious performance loss. Therefore, it is recommended to disable generic mode.
+
+
+Akkoma already avoids generic query plans by default, however the method it uses is not the most efficient because it needs to be compatible with all supported PostgreSQL versions. For PostgreSQL 12 and higher additional performance can be gained by adding the following to Akkoma configuration:
+```elixir
+config :pleroma, Pleroma.Repo,
+  prepare: :named,
+  parameters: [
+    plan_cache_mode: "force_custom_plan"
+  ]
+```

-## Emoji reactions
-
-Emoji reactions are implemented as a new activity type `EmojiReact`.
-A single user is allowed to react multiple times with different emoji to the
-same post. However, they may only react at most once with the same emoji.
-Repeated reaction from the same user with the same emoji are to be ignored.
-Emoji reactions are also distinct from `Like` activities and a user may both
-`Like` and react to a post.
-
-!!! note
-    Misskey also supports emoji reactions, but the implementations differs.
-    It equates likes and reactions and only allows a single reaction per post.
-
-The emoji is placed in the `content` field of the activity
-and the `object` property points to the note reacting to.
-
-Emoji can either be any Unicode emoji sequence or a custom emoji.
-The latter must place their shortcode, including enclosing colons,
-into `content` and put the emoji object inside the `tag` property.
-The `tag` property MAY be omitted for Unicode emoji.
-

-
-!!! note
-    Although an emoji reaction can only contain a single emoji,
-    for compatibility with older versions of Pleroma and Akkoma,

-## User profile backgrounds
-
-Akkoma federates user profile backgrounds the same way as Sharkey.
-
-An actors ActivityPub representation contains an additional
-`backgroundUrl` property containing an `Image` object. This property
-belongs to the `"sharkey": "https://joinsharkey.org/ns#"` namespace.
-
-## Quote Posts
-
-Akkoma allows referencing a single other note as a quote,
-which will be prominently displayed in the interface.
-
-The quoted post is referenced by its ActivityPub id in the `quoteUri` property.
-
-!!! note
-    Old Misskey only understood and modern Misskey still prefers
-    the `_misskey_quote` property for this. Similar some other older
-    software used `quoteUrl` or `quoteURL`.  
-    All current implementations with quote support understand `quoteUri`.
-

-
-## Threads
-
-Akkoma assigns all posts of the same thread the same `context`. This is a
-standard ActivityPub property but its meaning is left vague. Akkoma will
-always treat posts with identical `context` as part of the same thread.
-
-`context` must not be assumed to hold any meaning or be dereferencable.
-
-Incoming posts without `context` will be assigned a new context.
-
-!!! note
-    Mastodon uses the non-standard `conversation` property for the same purpose
-    *(named after an older OStatus property)*. For incoming posts without
-    `context` but with `converstions` Akkoma will use the value from
-    `conversations` to fill in `context`.
-    For outgoing posts Akkoma will duplicate the context into `conversation`.
-
-## Post Source
-
-Unlike Mastodon, Akkoma supports drafting posts in multiple source formats
-besides plaintext, like Markdown or MFM. The original input is preserved
-in the standard ActivityPub `source` property *(not supported by Mastodon)*.
-Still, `content` will always be present and contain the prerendered HTML form.
-
-Supported `mediaType` include:
-- `text/plain`
-- `text/markdown`
-- `text/bbcode`
-- `text/x.misskeymarkdown`
-
-## Post Language
-
-!!! note
-    This is also supported in and compatible with Mastodon, but since
-    joinmastodon.org doesn’t document it yet it is included here.
-    [GoToSocial](https://docs.gotosocial.org/en/latest/federation/federating_with_gotosocial/#content-contentmap-and-language)
-    has a more refined version of this which can correctly deal with multiple language entries.
-
-A post can indicate its language by including a `contentMap` object
-which contains a sub key named after the language’s ISO 639-1 code
-and it’s content identical to the post’s `content` field.
-
-Currently Akkoma, just like Mastodon, only properly supports a single language entry,
-in case of multiple entries a random language will be picked.  
-Furthermore, Akkoma currently only reads the `content` field
-and never the value from `contentMap`.
-
-## Local post scope
-
-Post using this scope will never federate to other servers
-but for the sake of completeness it is listed here.
-
-In addition to the usual scopes *(public, unlisted, followers-only, direct)*
-Akkoma supports an “unlisted” post scope. Such posts will not federate to
-other instances and only be shown to logged-in users on the same instance.
-It is included into the local timeline.  
-This may be useful to discuss or announce instance-specific policies and topics.
-
-A post is addressed to the local scope by including `<base url of instance>/#Public`
-in its `to` field. E.g. if the instance is on `https://example.org` it would use
-`https://example.org/#Public`.
-
-An implementation creating a new post MUST NOT address both the local and
-general public scope `as:Public` at the same time. A post addressing the local
-scope MUST NOT be sent to other instances or be possible to fetch by other
-instances regardless of potential other listed addressees.
-
-When receiving a remote post addressing both the public scope and what appears
-to be a local-scope identifier, the post SHOULD be treated without assigning any
-special meaning to the potential local-scope identifier.
-
-!!! note
-    Misskey-derivatives have a similar concept of non-federated posts,
-    however those are also shown publicly on the local web interface
-    and are thus visible to non-members.
-
-## List post scope
-
-Messages originally addressed to a custom list will contain
-a `listMessage` field with an unresolvable pseudo ActivityPub id.

 Then switch back to Pleroma for updates (similar to how was done to migrate to Akkoma), and remove the front-ends. The front-ends are installed in the `frontends` folder in the [static directory](../configuration/static_dir.md). Once you are back to Pleroma, you will need to run the database migrations again. See the Pleroma documentation for this.
