Release notes: Snapcraft 4.4
The team behind Snapcraft is pleased to announce the release of Snapcraft 4.4.
Highlights for this release include:
- improved font generation performance when desktop extensions
- updates to package repository definitions and behaviour
- metrics for Progressive Releases
- many small but significant bug fixes
For general details, including installation instructions, see Snapcraft overview, or take a look at Snapcraft release notes for other Snapcraft releases.
Custom CA certificates can now be added to the build environments created by Snapcraft by using
--add-ca-certificates with the lifecycle related commands.
This release includes a new mechanism to pre-generate font caches with desktop-related extensions. This enables system font cache generation at install time, isolated from the potentially (ABI) incompatible host-generated cache.
To benefit from this feature, extension snaps will need to be rebuilt. More details about this feature can be found in the specification.
The experimental package repositories has the following changes:
- the undocumented
$SNAPCRAFT_APTvariables have been removed.
- improved error handling and schema validation.
Additionally, the package repository specification has been finalised, hopefully opening a path to remove the experimental flag for this feature.
Updates to the Store
Metrics have been added to our progressive releases feature, as defined by the specification. Input on this feature is welcome on the forum.
See Progressive releases for more details.
revisions command is now internally using a new endpoint to provide much better results:
- table headers have changed to better represent architectures
- channels are now fully qualified (i.e.;
- comma separated column entries no longer have a space separating each item
Refer to the specification for further details.
