Snapcraft 3.1 is now available as a minor update to the Snapcraft 3.x series, adding build environment improvements to allow you to be once again able to clean parts using the “base” keyword while running the “snapcraft clean ” command, and offering you a more intuitive cleaning of steps from specific parts. The “cmake” and “rust” plugins have been updated as well in Snapcraft 3.1. While the “cmake” plugin gets two new features to allow you to package more applications in the Snap universal binary format, such as KDE apps, the “rust” plugin was revamped to work better with the non-legacy rustup tool.
