## Enabling `forget_rooms_on_leave` by default for Synapse
With the [Synapse v1.84.0 update](https://github.com/spantaleev/matrix-docker-ansible-deploy/pull/2698), we've also **changed the default value** of the `forget_rooms_on_leave` setting of Synapse to a value of `true`.
This way, **when you leave a room, Synapse will now forget it automatically**.
The upstream Synapse default is `false` (disabled), so that you must forget rooms manually after leaving.
**We go against the upstream default** ([somewhat controversially](https://github.com/spantaleev/matrix-docker-ansible-deploy/pull/2700)) in an effort to make Synapse leaner and potentially do what we believe most users would expect their homeserver to be doing.
If you'd like to go back to the old behavior, add the following to your configuration: `matrix_synapse_forget_rooms_on_leave: false`
