Release notes: Snapcraft 4.6

Snapcraft 4.6 is a feature-packed release, including:

  • new extensions
  • core20 support for additional extensions and plugins
  • a new login mechanism.
  • plenty of bug fixes and smaller updates

For general details, including installation instructions, see Snapcraft overview, or take a look at Snapcraft release notes for other Snapcraft releases.

Login mechanism

A new option, --experimental-login can now be used when using snapcraft login or snapcraft export-login and when signing assertions (see Create a developer account).

Using this option will trigger a web based authentication flow. To go back to the previous login method you must first snapcraft logout.

Conda plugin

The conda plugin has been ported to core20. These are the available plugin options:

  • conda-packages (list of strings)
    List of conda packages to install.
  • conda-python-version (string)
    The Python version to use for the conda packages.
    Python version major and minor version (e.g. 3.8).
  • conda-miniconda-version (string)
    The version of Miniconda to bootstrap.
    Defaults to the latest release.

Package Repositories

The road to making this feature stable is closer, although a breaking change lands with 4.6 for this experimental feature. Keys are now using the suffix and not prefix of the key id.

See Package repositories for further details.

Metadata

Snapcraft is now aware of the existence of kernel.yaml for snaps of type kernel.

The install-mode option for applications is now supported with this release.

Extensions

Gnome 3.38

The gnome-3-38 extension is now considered stable.

KDE Neon

The KDE Neon extension now supports core20 as an experimental extension.

Flutter

New variants of the Flutter extension are now available for stable and beta. The same documentation applies as for the master and dev variant.
