 - The `services.ananicy.extraRules` option now has the type of `listOf attrs` instead of `string`.
 
--  `matrix-synapse` now refers to a wrapper, encapsulating the original package, which has been renamed to `matrix-synapse-unwrapped`. The arguments `enableSystemd` and `enableRedis` have been removed. All extras can now be configured from [services.matrix-synapse.extras](#opt-services.matrix-synapse.extras), which configures the `extras` argument on the wrapper package. In most cases the required extras will automatically be discovered and installed, when relevant configuration sections are present.
+- The `matrix-synapse` package & module have undergone some significant internal changes, for most setups no intervention is needed, though:
+  - The option [`services.matrix-synapse.package`](#opt-services.matrix-synapse.package) is now read-only. For modifying the package, use an overlay which modifies `matrix-synapse-unwrapped` instead. More on that below.
+  - The `enableSystemd` & `enableRedis` arguments have been removed and `matrix-synapse` has been renamed to `matrix-synapse-unwrapped`. Also, several optional dependencies (such as `psycopg2` or `authlib`) have been removed.
+  - These optional dependencies are automatically added via a wrapper (`pkgs.matrix-synapse.override { extras = ["postgres"]; }` for `psycopg2` for instance) if the relevant config section is declared in `services.matrix-synapse.settings`. For instance, if [`services.matrix-synapse.settings.database.name`](#opt-services.matrix-synapse.settings.database.name) is `psycopg2`, `"postgres"` will be automatically added to the `extras` list of `pkgs.matrix-synapse`.
+  - A list of all extras (and the extras enabled by default) can be found at the [option's reference for `services.matrix-synapse.extras`](#opt-services.matrix-synapse.extras).
+  - In some cases (e.g. for running synapse workers) it was necessary to re-use the `PYTHONPATH` of `matrix-synapse.service`'s environment to have all plugins available. This isn't necessary anymore, instead `config.services.matrix-synapse.package` can be used as it points to the wrapper with properly configured `extras` and also all plugins defined via [`services.matrix-synapse.plugins`](#opt-services.matrix-synapse.plugins) available. This is also the reason for why the option is read-only now, it's supposed to be set by the module only.
