Release notes: Snapcraft 4.7
Snapcraft 4.7 is a feature-packed release, including:
- Validation sets for gated refresh control
- UA/ESM token support
- More architectures for the conda plugin and
- Desktop extension improvements around fonts
A validation set is an assertion that lists specific snaps that are either required to be installed together or are permitted to be installed together on a device or system.
This release of Snapcraft adds two commands for working with validation sets:
For more details, see Validation sets.
At the end of April, Ubuntu 16.04 LTS reached the end of its five years of mainstream support and entered the Extended Security Maintenance (ESM) phase.
To be able to continue building Ubuntu 16.04 LTS using the ESM base for local and on-premise builds, snap publishers and developers will need to obtain UA tokens. These tokens are free for all community users, for up to three machines, and up to 50 machines for Ubuntu members.
With this release of snapcraft, a new
--ua-token argument can be used to specify a token:
snapcraft <step> --ua-token <token>
See Snapcraft and Extended Security Maintenance for further details.
When using core20, the recently introduced conda plugin now supports more architectures, with the new ones being:
- i386 (x86)
- armhf (armv7l)
- ppc64el (ppc64le)
Extensions now have better font handling by integrating a new snapd feature to not expose the host font cache to the snap
when using the desktop related extensions.
General cleanup into the launcher script which ensures a proper environment has been setup is also part of this release.
Store whoami migration
snapcraft whoami command has fully migrated to the store
whoami endpoint, enabling logged in users, either with the existing flow or the experimental one, to query for their identity.
The stage-snaps keyword now allows specifying channel branches. This solves a long standing request.
