Understand how snaps update automatically, and use revisions and transactional updates to manage risk and mitigate potential issues.

• Refresh awareness: How updates are handled when apps are running.

• Using channels: Understanding channels, tracks, risk-levels and branches.

• Revisions: The unique identity for each and every snap version.

• Transactional updates: Update a group of snaps together, or none at all.

• Snap performance: How snaps limit any performance overhead.
