Features

• Add the ability to override the account validity feature with a module. (#9884)
• The spaces summary API now returns any joinable rooms, not only rooms which are world-readable. (#10298, #10305)
• Add a new version of the R30 phone-home metric, which removes a false impression of retention given by the old R30 metric. (#10332, #10427)
• Allow providing credentials to http_proxy. (#10360)

Bugfixes

• Fix errors during backfill caused by previously purged redaction events. Contributed by Andreas Rammhold (@andir). (#10343)
• Fix the user directory becoming broken (and noisy errors being logged) when knocking and room statistics are in use. (#10344)
• Fix newly added synapse_federation_server_oldest_inbound_pdu_in_staging prometheus metric to measure age rather than timestamp. (#10355)
• Fix PostgreSQL sometimes using table scans for queries against state_groups_state table, taking a long time and a large amount of IO. (#10359)

• Fix a number of logged errors caused by remote servers being down. (#10400, #10414)
