parentSupport MSC3283: Expose `enable_set_displayname` in capabilities (#10452) (diff)
downloadsynapse-000aa89be63c27092998eca03c97eaead21404cd.tar.xz
Do not include rooms with an unknown room version in a sync response. (#10644)
A user will still see this room if it is in a local cache, but it will
not reappear if clearing the cache and reloading.
