Hello Snapcrafters! The Snapcraft team is pleased to announce that version 2.43.1 is out.
This is a minor point release to fix some outstanding issues.

Contributions

This release saw some excellent contributions from outside the snapcraft core team, and we want to give a shout out to those folks. A team thank you to Evan Dandrea

New in this release

Core

Extensions

What was previously known as templates is now called extensions and the architecture on which this builds on is now pure python code to allow for future growth and decision making.

The rename takes place to convey that this functionality only extends an existing snapcraft.yaml and does not take part in modifying things that are only in place.

Containers

Build environments will soon be provided by multipass, guaranteeing more consistent results when builds are run from different machines. LXD containers (snapcraft cleanbuild today) will still be supported for existing projects.

In this release we catch up with snapd changes to continue offering a working snapcraft cleanbuild command.

Given the opportunity of modifying this code base, the logic to wait for cloud init has been improved.
