Just added manual server updates via the Settings interface to Kitten.
In the one-minute video you see:
1. An app running on latest Kitten version
2. I run ./install to create new local dev version
3. Settings page refreshes to show I’m running dev version
4. I hit a button to downgrade to the latest release version
5. I deploy a new version to kittens.small-web.org
6. Settings shows upgrade is available and I click to upgrade.
