Only the latest release is supported. The app checks for updates on launch, and fixes ship as new releases — there are no maintenance branches or backports.

Please do not open a public issue for security problems. Use GitHub's private reporting instead: Security → Report a vulnerability on this repository.

You'll get a first response within a few days. Accepted reports are fixed in a regular release, which the built-in updater delivers to all users — you'll be credited in the release notes unless you'd rather not be.
