Updating Devflow
Devflow checks for updates automatically and can install them in place.
When a new version is available for your channel, the app downloads the release package, verifies its SHA-256 checksum, and applies it by swapping in the new files and relaunching. You're prompted before an update is applied.
Updates are delivered from your configured Devtune server (devtune.app by default). You can change the update channel or trigger a manual check from Settings → Updates. Release notes for every version are published on the Changelog page.
