What probably matters to youSection of the release
Unclear What the sessionRecord capability actually enables isn't specified beyond its name and default.
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.
