Updating Handoff

Check for a New Version

.\handoff.exe update --check

This fetches <relay>/dl/handoff-version.json, prints the latest version and any release notes, and exits without downloading anything.

Download an Update

.\handoff.exe update

If a newer version is available, it is downloaded from <relay>/dl/handoff.exe and written next to the running binary as handoff.exe.new. The SHA-256 of the download is verified against the manifest before the file is written.

Handoff does not swap a running executable on Windows. To finish the update:

1. Close any running handoff processes.
2. Replace handoff.exe with handoff.exe.new (rename or copy).
3. Start a new session.
