We are happy to announce version 15 of osbuild. A handful of new features and, as usual, lots of bugfixes all over.

Below you can find the official changelog from the osbuild-15 sources. All users are recommended to upgrade!

• A new assembler, org.osbuild.oci-archive, that will turn a tree into an Open Container Initiative Image compliant archive. These archives can be used to run containers via e.g. podman.

• Support for client side certificates to download content from the Red Hat servers: the org.osbuild.files source got support for reading entitlements and pass those certificates along when fetching content, i.e. RPMs.

• A new ManifestPreProcessor (MPP) was added as a new tool located in tools/mpp-depsolve.py. Currently, it can take an existing manifest and dep-solve packages specified via a new mpp-depsolve option in existing org.osbuild.rpm stages. This is now used to generate Fedora 32 based test pipelines.

• The org.osbuild.ostree.commit assembler gained an option to produce a tarball archive instead of emitting the plain OSTree repository.

• Schema validation is now done with the draft 4 validator, and works therefore with pyhthon-jsonschema 2.6.

• The tree_id and output_id fields got dropped from the resulting JSON when inspecting pipelines via osbuild --inspect.

• The --build-env option has been dropped from the command line interface. It was deprecated and not used anymore.

• Tests have been converted to not rely on tree_id and output_id anymore, as they are deprecated and will be removed in the future.

• Lots of other improvements to the test infrastructure and the CI.

• And finally for something meta: this file has been re-formatted to be proper markdown.
