 The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/).
 
-## UNRELEASED
-
-## BREAKING
-- Minimum PostgreSQL version is raised to 12
-
-## 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
-
-## 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

-## ActivityPub
-
-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.
-
-### Required extensions
-
-#### 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.

 - `--keep-threads` - Don't prune posts when they are part of a thread where at least one post has seen local interaction (e.g. one of the posts is a local post, or is favourited by a local user, or has been repeated by a local user...). 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.
 - `--vacuum` - Run `VACUUM FULL` after the objects are pruned. This should not be used on a regular basis, but is useful if your instance has been running for a long time before pruning.
 
-## Prune orphaned activities from the database
-
-This will prune activities which are no longer referenced by anything.
-Such activities might be the result of running `prune_objects` without `--prune-orphaned-activities`.
-The same notes and warnings apply as for `prune_objects`.
-
-The task will print out how many rows were freed in total in its last
-line of output in the form `Deleted 345 rows`.  
-When running the job in limited batches this can be used to determine
-when all orphaned activities have been deleted.

-### Options
-
-- `--limit n` - Only delete up to `n` activities in each query making up this job, i.e. if this job runs two queries at most `2n` activities will be deleted. Running this task repeatedly in limited batches can help maintain the instance’s responsiveness while still freeing up some space.
-- `--no-singles` - Do not delete activites referencing single objects
-- `--no-arrays` - Do not delete activites referencing an array of objects

+## 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 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.

-## 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`.
-
-Example:
-```json
-{
-  "@context": [
-    "https://www.w3.org/ns/activitystreams",
-    "https://example.org/schemas/litepub-0.1.jsonld",

-```
-
-## 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.
