+## 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.

 - Follows no longer override domain blocks, a domain block is final

 ## Restore/Move
 
 1. Optionally reinstall Akkoma (either on the same server or on another server if you want to move servers).
 2. Stop the Akkoma service.
 3. Go to the working directory of Akkoma (default is `/opt/akkoma`)
 4. Copy the above mentioned files back to their original position.
-5. Drop the existing database and user if restoring in-place. `sudo -Hu postgres psql -c 'DROP DATABASE <akkoma_db>;';` `sudo -Hu postgres psql -c 'DROP USER <akkoma_db>;'`

-6. Restore the database schema and akkoma postgres role the with the original `setup_db.psql` if you have it: `sudo -Hu postgres psql -f config/setup_db.psql`.
+6. Restore the database schema and akkoma role using either of the following options
-
+    * You can use the original `setup_db.psql` if you have it[²]: `sudo -Hu postgres psql -f config/setup_db.psql`.
-  Alternatively, run the `mix pleroma.instance gen` task again. You can ignore most of the questions, but make the database user, name, and password the same as found in your backup of `config/prod.secret.exs`. Then run the restoration of the akkoma role and schema with of the generated `config/setup_db.psql` as instructed above. You may delete the `config/generated_config.exs` file as it is not needed.
+    * Or recreate the database and user yourself (replace the password with the one you find in the config file) `sudo -Hu postgres psql -c "CREATE USER akkoma WITH ENCRYPTED PASSWORD '<database-password-wich-you-can-find-in-your-config-file>'; CREATE DATABASE akkoma OWNER akkoma;"`.

 9. Restart the Akkoma service.
 10. Run `sudo -Hu postgres vacuumdb --all --analyze-in-stages`. This will quickly generate the statistics so that postgres can properly plan queries.
 11. If setting up on a new server configure Nginx by using the `installation/akkoma.nginx` config sample or reference the Akkoma installation guide for your OS which contains the Nginx configuration instructions.

You can ignore most of the questions, but make the database user, name, and password the same as found in your backed up config file. This will also create a new `config/generated_config.exs` file which you may delete as it is not needed.  
+[³]: `pg_restore` will add data before adding indexes. The indexes are added in alphabetical order. There's one index, `activities_visibility_index` which may take a long time because it can't make use of an index that's only added later. You can significantly speed up restoration by skipping this index and add it afterwards. For that, you can do the following (we assume the akkoma.pgdump is in the directory you're running the commands):  
+
+```sh
+pg_restore -l akkoma.pgdump > db.list
+
+# Comment out the step for creating activities_visibility_index by adding a semi colon at the start of the line
+sed -i -E 's/(.*activities_visibility_index.*)/;\1/' db.list
+
+# We restore the database using the db.list list-file
+sudo -Hu postgres pg_restore -L db.list -d akkoma -v -1 akkoma.pgdump
+
+# You can see the sql statement with which to create the index using
+grep -Eao 'CREATE INDEX activities_visibility_index.*' akkoma.pgdump
+
+# Then create the index manually
+# Make sure that the command to create is correct! You never know it has changed since writing this guide
+sudo -Hu postgres psql -d pleroma_ynh -c "CREATE INDEX activities_visibility_index ON public.activities USING btree (public.activity_visibility(actor, recipients, data), id DESC NULLS LAST) WHERE ((data ->> 'type'::text) = 'Create'::text);"
+```
+[⁴]: Prefix with `MIX_ENV=prod` to run it using the production config file.  
 
 ## Remove
 
 1. Optionally you can remove the users of your instance. This will trigger delete requests for their accounts and posts. Note that this is 'best effort' and doesn't mean that all traces of your instance will be gone from the fediverse.
     * You can do this from the admin-FE where you can select all local users and delete the accounts using the *Moderate multiple users* dropdown.
-    * You can also list local users and delete them individualy using the CLI tasks for [Managing users](./CLI_tasks/user.md).

+# 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
+
+=== "Nginx"
+
+    upstream phoenix {
+        server 127.0.0.1:6081 max_fails=5 fail_timeout=60s;
+    }
+
+
+=== "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";
+}
+```
+
+This will allow your webserver alone to handle redirects.
