The only release note worthy point for this release is: if you're using the
horrendous `compose.keycloak2.yml` (as creator of this horrible hack, I am
allowed to call it horrendous ;)), you will need to re-check the new
~/.abra/recipes/matrix-synapse/.env.sample, there are some new default env vars
which you'll have to add in (e.g. KEYCLOAK2_ID=...).
