New in this release


snapcraft CLI

This has been a highly requested change in snapcraft, the CLI has been refactored to provide a much cleaner interface to the user (without breaking backwards compatibility). The diferences between one version and the other can be seen on this forum post


The preliminary support for snapcraft to have a container assigned per project has been extended to work with all of the snapcraft build commands, still hidden by the feature flag, SNAPCRAFT_CONTAINER_BUILDS needs to be set. Read more and track it on this forum post

cleanbuild now correctly works when using the :arch syntax in build-packages and stage-packages, this is for example, having a stage-packages entry that ends with :i386 when cleanbuilding on amd64.

asset recording

Asset recording is a feature with two benefits, easier tracking of what is in a snap and also provides enough information to rebuild a snap with the information provided. The plumbing work is nearly done ironing out minor issues. If SNAPCRAFT_BUILD_INFO is set in the environment, the resulting snap will have a snap/snapcraft.yaml which can be use to rebuild the same snap.

More about the final results of asset recording can be looked up on this forum post


There is now support for 7-zip files, if your source has the extension .7z it should just work. If not, it can be used by setting source-type to 7z.



A new plugin has made it to snapcraft, a plugin to work with meson, run snapcraft help meson to get acquainted with the plugin.


The rust plugin now correctly works when source-subdir is set.


The kernel plugin has received a lot of attention this cycle. It correctly provides warnings when certain features are not enabled that would be required for a system to boot.

The plugin has also gained a new property kconfigflavor that works with the knowledge of Ubuntu kernel configurations to assemble a kernel config.

Store integration

snap collaboration

The user interface for this feature has been completed. Hidden in APIs until the store enables the feature so the story is complete.


Snapcraft has been enhanced to display branch information for the relevant commands.
