🪦 The playbook used to be able to install and configure the sliding-sync proxy, but no longer includes this component, as it’s been replaced with a different method (called Simplified Sliding Sync) integrated to newer homeservers by default (Conduit homeserver from version 0.6.0 or Synapse from version 1.114).
If you still have the Sliding Sync proxy installed on your Matrix server, the playbook can no longer help you uninstall it and you will need to do it manually. To uninstall manually, run these commands on the server:
systemctl disable --now matrix-sliding-sync.service
rm -rf /matrix/sliding-sync
/matrix/postgres/bin/cli-non-interactive 'DROP DATABASE matrix_sliding_sync;'
