What

Background session adoption compares the recorded session's cliVersion against the running build and skips the upgrade respawn when the running session is already newer, instead of treating any version difference as stale.

Details
  • affects both background session adoption and the upgrade-respawn path
  • a version mismatch alone is no longer sufficient to force a respawn
  • applies to everyone

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