Snapcraft 2.16 comes two weeks after the release of the previous maintenance update, namely Snapcraft 2.15.1, and it introduces a bunch of new variables, which application developers who want to package their apps in the Snap universal package format can use within the snapcraft.yaml file and exported in the environment when plugins run. Moreover, Snapcraft 2.16 adds support for parameters to the ANT plugin, and it looks like the “snapcraft register –private” command was updated to support registration of private Snaps.
