There was also a 2.1.5 security release made today.
2.2.0 contains the same security fix + more.

Both make handling of Client-Server API v3-prefixed requests better.

We had to remove UID/GID environment variables that we used to pass
to the Synapse container, because it was causing a problem after
https://github.com/matrix-org/synapse/pull/11209

We were using both `--user` and UID/GID environment variables until now.

https://github.com/mautrix/facebook/releases/tag/v0.3.2 says that this
version re-adds SQLite support.

Official support ends today (2021-11-11).
Synapse still supports v9.6, but we'd better force users to transition
to newer versions anyway.

Until now, we were leaving services "enabled"
(symlinks in /etc/systemd/system/multi-user.target.wants/).

We clean these up now. Broken symlinks may still exist in older
installations that enabled/disabled services. We're not taking care
to fix these up. It's just a cosmetic defect anyway.

Regresion since https://github.com/spantaleev/matrix-docker-ansible-deploy/pull/1139

We were applying the low-memory system patch to webpack.config.js
on systems with < 4GB memory.

From now on, we also let people force-enable patching by toggling the
`matrix_client_element_container_image_self_build_low_memory_system_patch_enabled`
variable.
