Module update 

Functions

check_now

Ask GitHub right now — no interval — and say where the installed build stands.

maybe_auto_update

The end-of-run hook behind auto_update: when the setting is on and the last release check already knows a newer version exists, replace the binary without being asked.

notify_if_outdated

Quietly keep the release check current and print a one-line notice when the installed build is behind. Returns true when the registry changed and needs saving.
