System Sleep Detection for WebSocket Connections

Entry
JSON All of v2.1.50
EntryKind: in v2.1.50,
ChangesSection of the release
What

Improved reconnection handling when the system wakes from sleep.

Details
  • Detects large time gaps between reconnection attempts indicating system sleep
  • Resets the reconnection budget after sleep to avoid exhausting retries
  • Adds periodic keep-alive frames for more reliable connection maintenance
Evidence

Sleep detection logic (search for "Detected system sleep", "resetting reconnection budget")

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