v1.41.0

Synapse 1.41.0 (2021-08-24)

This release adds support for Debian 12 (Bookworm), but removes support for Ubuntu 20.10 (Groovy Gorilla), which reached End of Life last month.

Note that when using workers the /_synapse/admin/v1/users/{userId}/media must now be handled by media workers. See the upgrade notes for more information.

Features

• Enable room capabilities (MSC3244) by default and set room version 8 as the preferred room version when creating restricted rooms. (#10571)

• Initial local support for MSC3266, Room Summary over the unstable /rooms/{roomIdOrAlias}/summary API. (#10394)

• Add a configuration setting for the time a /sync response is cached for. (#10513)
• The default logging handler for new installations is now PeriodicallyFlushingMemoryHandler, a buffered logging handler which periodically flushes itself. (#10518)
• Add support for new redaction rules for historical events specified in MSC2716. (#10538)
• Add a setting to disable TLS when sending email. (#10546)
• Add pagination to the spaces summary based on updates to MSC2946. (#10549, #10560, #10569, #10574, #10575, #10579, #10583)

• Add an admin API (GET /_synapse/admin/username_available) to check if a username is available (regardless of registration settings). (#10578)
• Allow editing a user's external_ids via the "Edit User" admin API. Contributed by @dklimpel. (#10598)

Bugfixes

• Add some clarification to the sample config file. Contributed by @Kentokamoto. (#10129)
• Fix a long-standing bug where protocols which are not implemented by any appservices were incorrectly returned via GET /_matrix/client/r0/thirdparty/protocols. (#10532)
• Fix exceptions in logs when failing to get remote room list. (#10541)
• Fix longstanding bug which caused the user's presence "status message" to be reset when the user went offline. Contributed by @dklimpel. (#10550)
• Allow public rooms to be previewed in the spaces summary APIs from MSC2946. (#10580)
• Fix a bug introduced in v1.37.1 where an error could occur in the asynchronous processing of PDUs when the queue was empty. (#10592)
• Fix errors on /sync when read receipt data is a string. Only affects homeservers with the experimental flag for MSC2285 enabled. Contributed by @SimonBrandner. (#10606)
• Additional validation for the spaces summary API to avoid errors like ValueError: Stop argument for islice() must be None or an integer. The missing validation has existed since v1.31.0. (#10611)
• Revert behaviour introduced in v1.38.0 that strips org.matrix.msc2732.device_unused_fallback_key_types from /sync when its value is empty. This field should instead always be present according to MSC2732. (#10623)
