MSC4239: Room version 11 as the default room version
Room version 11 was introduced in Matrix 1.8 back in August 2023. The room version is a light cleanup from room version 10, particularly around the redaction algorithm. There are no other major changes.
Over the last year since release, the expectation was that there might be a room version 12 in quick succession, however as is tradition for any expectation, things changed. This proposal bumps the default suggested room version from version 10 to version 11, bringing the redaction algorithm cleanup to the wider ecosystem.
Proposal
The specification adopts room version 11 as the suggested default room version. No stability status changes are made to any room version.
Potential issues
Some servers may not have updated to support version 11 yet, though many servers support version 10. The delta between the versions is minimal.
Alternatives
No relevant alternatives.
Security considerations
No relevant security considerations (they would have been made in MSC3820).
Unstable prefix
No relevant prefix - servers can already choose a different default room version. This MSC formalizes the default.
Dependencies
No outstanding blockers are listed.
