Session Persistence Optimization

Entry
JSON All of v2.0.23
EntryKind: in v2.0.23,
ChangesSection of the release

Improved the session persistence mechanism by adding request queuing and serialization to prevent race conditions when multiple session updates occur simultaneously. The system now uses a Map-based queue (fTQ) to ensure session persistence operations are processed sequentially per session.

Evidence

New function hTQ() at line 457187 wraps session persistence calls with queue management, while qM8() at line 457135 handles the actual persistence logic.

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
