Snapcraft 8.12 release notes¶

4 September 2025

Learn about the new features, changes, and fixes introduced in Snapcraft 8.12.

Requirements and compatibility¶

See System requirements for information on the minimum hardware and installed software.

What’s new¶

Snapcraft 8.12 brings the following features, integrations, and improvements.

New metadata linter¶

A new linter is available to help identify problems in a project’s metadata keys. If your project has a stable grade, the linter warns you if the title, contact, or license keys are missing or malformed. Likewise, if the donation, issues, source-code, or website keys are missing or malformed, the linter logs it.

See Ignore specific keys of the metadata linter for guidance on customizing the behavior of this linter.

Minor features¶

Remote builds: `--build-for` and shorthand platforms¶

Previously, the remote builder couldn’t accept the --build-for argument when building core24 snaps with a shorthand platforms definition.

Due to improvements made by the Launchpad team, --build-for can now be used when building core24 snaps remotely.

Improved usability when piping `status` output¶

The output of snapcraft status was reworked to allow for easier parsing. Prior to the change, the output was formatted as follows:

user@host:~$

snapcraft status snapcraft | grep pr- | head
