What probably matters to youSection of the release
What
A remote control client can now send keep_session_on_exit (client-side option keepSessionOnExit) when it connects, and the session record is kept rather than archived when Remote Control is later disabled.
Details
The flag sets an internal never-archive marker on the remote control connection; while it is set, the archive step does nothing and the session is released with its record retained.
Only takes effect if the connecting client sends the flag. Without it, the previous behaviour of archiving on exit is unchanged.
