Updating

koban update keeps direct binary installs current by downloading GitHub release tarballs and verifying their checksums.

koban update --check          # report whether a newer release exists
koban update                  # download and install the latest release
koban update --tag v0.2.0     # install a specific tagged release
koban update --nightly --check
koban update --nightly        # install the latest rolling nightly

Flag	Purpose
--check	Report available updates without installing.
--tag <t>	Install a specific release tag.
--nightly	Target the rolling nightly prerelease channel.
--force	Reinstall even if already up to date.

Package-manager installs

If koban was installed via a package manager (rather than the curl | sh installer or a release tarball), koban update leaves the installed binary alone and prints an upgrade recipe for that package manager instead.

Nightly channel

The nightly workflow builds the current main branch into a rolling nightly prerelease. It stages assets in a nightly-staging release while compiling, so the previous nightly stays available to updater clients until the new assets are ready. koban update --nightly tracks that channel.
