What probably matters to youSection of the release
Unclear What sessionRecord actually does for the user (e.g. recording session activity) is not stated, only that it gates behavior.
What
The capability map used in remote/session negotiation gains a new sessionRecord entry, alongside existing entries like controlChannel, modelCatalog, setPermissionMode, fanout, presence, catchupReplay, bashExec, and fileRead. It defaults to false.
The flag is read in two places: an origin/mode tracking effect and an internal remote-transport check, and both reads are further gated by a call to vs().
Why
This lets Claude Code check whether a remote session supports recording before turning related behavior on. Because the flag defaults to off, it has no effect on existing sessions until it is explicitly enabled.
