If you're a Snap app developer, you'll be glad to know that Canonical will now send you alerts via email everytime new Ubuntu Security Notices (USNs) are published and contain details about security fixes for the staged packages in the Snap. This will work only if you use "stage-packages" in Snap's snapcraft.yaml configuration file. Snaps are already secure by design, as they run as containerized software packages isolated from the rest of the host system. On top of that, they automatically update themselves, are simple to install without the hustle of countless dependencies. However, Canonical's new security alerts for developers make them even more secure.
