              <p>
                Every snap can offer multiple streams of updates &mdash; called  channels &mdash; including the version and maturity -edge, beta, stable- of the snap . Switch to ‘3.2/stable’ and you know what you’ll be getting on that machine.
              </p>
              <p>
                That means you can go closer to the edge to see what features are coming, experiment with various versions to see which one suits you best, or stick to the recommended stable branch.

              The content that ships inside snaps is compressed and remains compressed and read-only through the whole life time of the snap, even during normal use after installation. This means the original package digest and signature is never touched.

                The kernel and base operating system are handled as snaps as well, so all the benefits that apply to applications also apply to the system foundation. This means not only benefitting from fast and consistent updates to the core, but also graceful error handling with automatic rollbacks on improperly updated kernels.
