[TESTING] dbsearch: actually rank search results

Until now we always sorted search matches by id (basically: most recent)
and grabbed the first couple. However, if no special input modifiers are
used websearch_to_tsquery creates a pretty loose search vector and the
most recent matches might be far from the most relevant matches.

Thus rank results by their relevancy instead. Normalisation mode 16
takes the amount of unique words of a post into account since a
post with 500 unique words matching a 5 word query is likely less
relevant than a post consisting entirely out of the 5 queried words.

Let’s hope this improves on our notoriously bad search.

The tradeoff here being more costly queries. ON a simplified mockup
query without any filtering or joins with activities, the planner’s
cost estimate didn’ŧ change much, but measured wall clock time for
a single query increased from ~1.7ms to 2.3ms.

As far as I can tell, the cost of ts_rank(_cd) was never discussed
before. The original version 9f0a2a714b
didn’t sort at all and there’s no associated discussion. Later it was
sorted by date 1dd2c8163f but quickly
changed to sorting by id ff5e957476
(which isn’t to different with old sequential ids and current FlakeIDs).
This was carried forward until eventually being removed in
817c66bc3e prob because pagination sorts
anyway.

For now RUM results continue to be ranked solely by recencey
as it did since its introduction in
  01c45ddc9e and
  f1e67bdc31
It is possible to make it use an efficient relevancy-based ranking,
but this requires changes to its index which is beyond the scope of
this commit.

TODO: not sure how much the normalisation helps or if a non-log
  or non-unique word normalisation would be better.

 ## Unreleased
 
+## Fixed
+- Search results for the default built-in GIN search are now actually ranked by relevancy
+
+## 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
+
+## 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
+
+## 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
+
+## 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
+
+## 2023.08
+
 ## Added
 
 - Added a new configuration option to the MediaProxy feature that allows the blocking of specific domains from using the media proxy or being explicitly allowed by the Content-Security-Policy.
   - Please make sure instances you wanted to block media from are not in the MediaProxy `whitelist`, and instead use `blocklist`.
 - `OnlyMedia` Upload Filter to simplify restricting uploads to audio, image, and video types
+- ARM64 OTP builds
+  - Ubuntu22 builds are available for develop and stable
+  - other distributions are stable only
+- Support for Elixir 1.15
+  - 1.14 is still supported
+  - OTP26 is currently "unsupported". It will probably work, but due to the way
+    it handles map ordering, the test suite will not pass for it as yet.
+
+## Changed
+
+- Alpine OTP builds are now from alpine 3.18, which is OpenSSLv3 compatible.
+  If you use alpine OTP builds you will have to update your local system.
+- Debian OTP builds are now from a base of bookworm, which is OpenSSLv3 compatible.
+  If you use debian OTP builds you will have to update your local system to
+  bookworm (currently: stable).
+- Ubuntu and debian builds are compatible again! (for now...)
+- Blocks/Mutes now return from max ID to min ID, in line with mastodon.
+- The AnonymizeFilename filter is now enabled by default.
 
 ## Fixed
 
 - Deactivated users can no longer show up in the emoji reaction list
 - Embedded posts can no longer bypass `:restrict\_unauthenticated`
+- GET/HEAD requests will now work when requesting AWS-based instances.
+
+## Security
+
+- Add `no_new_privs` hardening to OpenRC and systemd service files
+- XML parsers cannot load any entities (thanks @Mae@is.badat.dev!)
+- Reduced permissions of config files and directories, distros requiring greater permissions like group-read need to pre-create the directories
+
+## Removed
+
+- Builds for debian oldstable (bullseye)
+  - If you are on oldstable you should NOT attempt to update OTP builds without
+    first updating your machine.

 - Rich media will now hard-exit after 5 seconds, to prevent timeline hangs
 - HTTP Content Security Policy is now far more strict to prevent any potential XSS/CSS leakages
 - Follow requests are now paginated, matches mastodon API spec, so use the Link header to paginate.

 ### Detecting flavour
 
-This is a little more complex than it used to be (thanks ubuntu)
