What probably matters to youSection of the release
What
A process can now start the debug logger with syncExitDrain: false, and when the v5 log storage backend is in use, queued lines still pending at exit are dropped instead of written. Startup prints a warning that the log may be truncated. Without an explicit false, the logger still drains as before.
Details
Both conditions are required: the option set explicitly to false and the v5 storage backend active.
Evidence
Sync exit drain off for this process: debug lines still queued at exit are dropped, so this log may end short
Strings lifted out of the shipped bundle, so the claim above can be checked against them.
