We are happy to announce version 20 of osbuild. This time with a big set of new features, including support for btrfs assemblers, as well as reworked and improved progress output on the terminal. As usual, a round of bugfixes is included as well.

Below you can find the official changelog from the osbuild-20 sources. All users are recommended to upgrade!

• The filesystem assemblers gained support for btrfs. They can now output image files as btrfs, similar to the existing support for ext4 and xfs.

• The --libdir=DIR handling was generalized in that an empty osbuild subdirectory will now always cause osbuild to use the system osbuild package. This means a custom libdir via --libdir=DIR no longer requires the entire osbuild python package to be bundled in an osbuild subdirectory.

• When run on a terminal, osbuild will now output the duration of a stage (or other module).

• The --output-directory switch is now mandatory if no checkpoint was specified. In this situation, running osbuild would be a no-op.

• The ostree assembler now optionally emits version metadata in its commits.

• osbuild now supports running on Ubuntu-20.04.

• Modules can now pass metadata alongside the filesystem objects they emit. This metadata is not stored in the final artifact, but passed to the caller via the structured osbuild output.

• The ostree assembler now emits compose metadata as part of its build. This can be inspected by the caller to get detailed compose information.

• The rpm stage now emits detailed metadata about the installed RPM packages.

• Lots of fixes all over the place, including SELinux reworks and PEP-8 conformance.
