-This MSC proposes changing the recommended default room version from v4 to v5. This implements steps 5 and 6 of the plan from [MSC2002](https://github.com/matrix-org/matrix-doc/issues/2002).

 ## Proposal
 
-When [MSC2077](https://github.com/matrix-org/matrix-doc/issues/2077) proposed room version 5, the default version continued to be v4 to allow old servers to continue to chat in newly created rooms. Server-Server API r0.1.2 (which contains the details on room version 5) and Synapse 1.0.0 (with support for room version 5) were both released more than 4 months ago which has given people plenty of time to update. Room version 5 should be the default room version so that newly created rooms enforce key-validity periods.

 ## Potential issues
 
-Servers which do not support room version 5 will not be able to participate in newly created rooms on other servers. Hopefully this will encourage them to update their server.

 ## Security considerations
 
-Room version 5 fixes known security vulnerabilities but that doesn't do much good if newly created rooms aren't using room version 5 by default.
