CHANGELOG.md

@@ -6,11 +6,39 @@ The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/).
 
 ## Unreleased
 
+## Removed
+- Non-finch HTTP adapters
+
+## Upgrade notes
+- Ensure `config :tesla, :adapter` is either unset, or set to `{Tesla.Adapter.Finch, name: MyFinch}` in your .exs config
+
+## 2022.12
+
 ## Added
 - Config: HTTP timeout options, :pool\_timeout and :receive\_timeout
+- Added statistic gathering about instances which do/don't have signed fetches when they request from us
+- Ability to set a default post expiry time, after which the post will be deleted. If used in concert with ActivityExpiration MRF, the expiry which comes _sooner_ will be applied.
+- Regular task to prune local transient activities
+- Task to manually run the transient prune job (pleroma.database prune\_task)
+- Ability to follow hashtags
+- Option to extend `reject` in MRF-Simple to apply to entire threads, where the originating instance is rejected
+- Extra information to failed HTTP requests
 
 ## Changed
 - MastoAPI: Accept BooleanLike input on `/api/v1/accounts/:id/follow` (fixes follows with mastodon.py)
+- Relays from akkoma are now off by default
+- NormalizeMarkup MRF is now on by default
+- Follow/Block/Mute imports now spin off into *n* tasks to avoid the oban timeout
+- Transient activities recieved from remote servers are no longer persisted in the database
+- Overhauled static-fe view for logged-out users
+- Blocked instances will now not be sent _any_ requests, even fetch ones that would get rejected by MRF anyhow
+
+## Removed
+- FollowBotPolicy
+- Passing of undo/block into MRF
+
+## Upgrade Notes
+- If you have an old instance, you will probably want to run `mix pleroma.database prune_task` in the foreground to catch it up with the history of your instance.

+# Using a Varnish Cache
+
+Varnish is a layer that sits between your web server and your backend application -
+it does something similar to nginx caching, but tends to be optimised for speed over
+all else.
+
+To set up a varnish cache, first you'll need to install varnish. 
+
+This will vary by distribution, and since this is a rather advanced guide,
+no copy-paste instructions are provided. It's probably in your distribution's
+package manager, though. `apt-get install varnish` and so on.
+
+Once you have varnish installed, you'll need to configure it to work with akkoma.
+
+Copy the configuration file to the varnish configuration directory:
+
+    cp installation/akkoma.vcl /etc/varnish/akkoma.vcl
+
+You may want to check if varnish added a `default.vcl` file to the same directory,
+if so you can just remove it without issue.
+
+Then boot up varnish, probably `systemctl start varnish` or `service varnish start`.
+
+Now you should be able to `curl -D- localhost:6081` and see a bunch of
+akkoma javascript.
+
+Once that's out of the way, we can point our webserver at varnish. This

+
+
+=== "Caddy"
+
+    reverse_proxy 127.0.0.1:6081
+
+Now hopefully it all works
+
+If you get a HTTPS redirect loop, you may need to remove this part of the VCL
+
+```vcl
+if (std.port(server.ip) != 443) {
+      set req.http.X-Forwarded-Proto = "http";
+      set req.http.x-redir = "https://" + req.http.host + req.url;
+      return (synth(750, ""));
+} else {
+  set req.http.X-Forwarded-Proto = "https";
+}
+```
