  * Qcow and openstack images for Fedora have now cloudinit service enabled
    by default. This change leads to a higher consistency with the official
  * Fedora 32 image builds were failing if an installed package shipped
    a custom SELinux policy. This is now fixed.

  * The DNF integration now uses the fastestmirror plugin. This should lead
    to faster and more reliable depsolves.

  * Tar archives returned from Weldr routes could have contained files with
    a timestamp newer than the current time. This led to warnings when
    untarring these archives. The timestamps are now fixed.
  * The RCM subpackage was removed. It was never properly finished and will
    be superseded by a Koji integration at some point.

  * AWS images are now built in the raw format. Previously used vhdx was
    space-efficient but actually caused about 30% of uploads to fail.

  * The spec file had a wrong version of lorax-composer to obsolete, causing
    upgrades to fail. This is now fixed.

  * osbuild-composer now obsoletes lorax-composer on RHEL.

  * An upload failure (e.g. due to invalid credentials) now causes the compose
    to appear as failed.
  * RHEL 8 repositories are switched to the beta ones to allow composer to be
    tested on 8.3 Beta. This will be reverted when GA comes.
  * OSTree images no longer contains /etc/fstab. The filesystem layout is
    determined by the installer and thus it doesn't make any sense to include
  * If both group and user customizations were used, the user would be created
    before the group, causing a build to fail. This is now fixed.
  * Composer now correctly passes UID and GID to org.osbuild.{users,groups}
    stages as ints instead of strings.

  * The subpackages (worker, tests and rcm) now require a matching version of
    osbuild-composer to be installed. Previously, they would be happy with
    just an arbitrary one.

  * Support for testing OpenStack images in actual OpenStack is now available.
    Note that upload to OpenStack is still not available for the end users
    (it's on the roadmap though).
  * Worker now logs not only job failures but also job successes.
  * All DNF errors were mistakenly tagged as RepoError, this is now fixed.
  * As always, a lot of test and CI improvements are included in this release.

  * Support for building RHEL for Edge is now available.

  * Composer has now support for building QCOW2 and tar images for ppc64le and
    s390x architectures.
  * Tar images for RHEL have returned. The Image Builder team found out that
    they are used as a way to install RHEL for Satellite.

  * Blueprints containing packages with a wildcard version no longer causes
    the built image to have both x86_64 and i686 versions of one package
  * GPG check is now disabled by default. If you have a custom
    repository in /etc/osbuild-composer/repositories, just set gpg_check
    to true to enable the check. Note that all the pre-defined repositories
    have GPG check enabled.
  * Composer now supports a cancellation of jobs. This can be done by calling
    /compose/cancel route of Weldr API.
  * osbuild-composer previously crashed when osbuild didn't return the right
    machine-readable output (e.g. because of a disk being out of space). This
    is now fixed.
  * Because of the GPG check change and RHEL for Edge support, composer
    now requires osbuild 17 or higher.
  * osbuild-composer previously required the python package to be installed
    on RHEL. Now, it uses the always-installed platform-python.

  * The buildroot for RHEL 8 didn't have selinux labels before. This is now
  * When Composer crashed, it left temporary directories in /var/cache. The
    temporary directories are now moved to /var/tmp, which is managed by
    systemd with PrivateTmp set to true, so they're now correctly removed
    after a crash.
  * Several weldr API routes were aligned to work in the same way as with
    Lorax. /blueprints/freeze now correctly supports option to output TOML.
    Projects and modules routes return all fields as Lorax returns.

  * AWS upload now logs the current state to the system journal. Emojis are
    of course included. 🎉
  * As always, amazing improvements in the CI infrastructure happened. Also,
    the test coverage went up. Thanks all for doing this!

  * AWS uploads doesn't anymore report to AWS that composer uploads
    the image in vhdx format. This surprisingly makes the upload process
    more stable.

  * Uploads were always in WAITING state. This is now fixed.
  * The /projects/source/* routes now correctly supports all the features
    of Weldr API v1. 

  * AWS upload now logs the progress to journal. Even better logging is
    hopefully coming soon.
  * AWS upload's status is now correctly set to FAILED when ImportSnapshot
    fails. Before, this hanged the upload indefinitely.

  * Store unmarshalling is now safer in some cases. For example, stored
    manifests are now longer checked when loaded from disk. Therefore,
    changing of manifest schema doesn't lead to crashes when old manifests
    are present in the store.
  * When store loading failed in non-verbose mode of osbuild-composer, it
    crashed the process because of nil logger. This is now fixed.

  * The upstream spec file for building osbuild-composer package now
    excludes the i686 architecture. Note that composer never supported
    this arch.
  * The upstream spec file now correctly specifies the composer's dependency
    to osbuild-ostree. This was forgotten in the previous release which
    introduced Fedora IoT support.

  * The previous version didn't have repositories defined for s390x and
    ppc64le architectures. This is now fixed. Note that this only fixes
    some codepaths, osbuild-composer still cannot build any images on
    these architectures.

  * Fedora IoT is now supported for Fedora 32 in the form of producing the
    commit tarball. Feel free to test it and report any issues you find.

  * Support for RHEL was completely revamped. Now, osbuild-composer supports
    building images only for the latest RHEL 8. The separate minor versions
    are no longer available. Additionally, it now uses the Red Hat CDN which
    requires the host system to be properly subscribed. If you need to use
    different package repositories to build RHEL from, use a repository
    override in /etc/osbuild-composer/repositories.
  * Several image types were removed: ext4-filesystem, partitioned-disk,
    and tar. The use-cases for these image types were not clearly defined and
    without a clear definition, it was very hard to define test cases for
  * Support for Fedora 30 was dropped as it is now EOL. So long and thanks
    for all the fish!

  * The timeout for AWS upload is removed. It's very hard to predict how long
    will the AWS upload take. With the timeout in place, it caused the test
    suite to produce a lot of false positives.
  * Build logs were broken in the previous release, this release fixes it.
    This time, they were properly saved but weldr API read them from a wrong
    location. This is now fixed and covered with basic tests.
  * Weldr API has now support for /compose/metadata and /compose/results
    routes. This allows users to easily access a manifest used to build
    an image.
  * Preliminary support for ppc64le and s390x is added to RHEL distribution.
    No images cannot be built yet but at least it won't crash on startup.
  * The weldr API socket has now correct permissions. As the result, it can
    be read and written only by root and the weldr group. This is the same
    behaviour as Lorax has.
  * By mistake, workers incorrectly used the default store for every build.
    However, this can currently cause the store to grow indefinitely, so
    this release switched the osbuild store to use a temporary directory again.
  * /status route in weldr API now correctly returns msgs field.

  * Handling of json (un)marshalling in store is revamped. It should
    make it more stable and simplify the maintenance of the store backwards

  * Initial support for koji is now added. It's currently not hooked up
    to composer and only supports password authentication. More coming soon.
  * Again, the automated testing was greatly improved during this cycle,
    big thanks to everyone involved!

  * In previous versions support for running remote workers was
    broken. This is now fixed and running remote workers is once
    again possible. See #568 for more information.

  * The job queue and the store are now two separate Go packages.
    One of the benefits is that it is now possible to build images
    without using the store which is too complicated for some usecases.

  * A blueprint name is now checked against the regex
    `^[a-zA-Z0-9._-]+$`. This is the same limitation as in

  * All osbuild calls now use the new --output-directory argument.
    This change is a must because the old way of retrieving images from
    the osbuild store will soon be deprecated.

  * Some routes from the weldr API are now implemented in a more
    efficient way.

  * As always, the team worked hard on improving the tests and the CI.

  * The support for uploading VHD images to Azure is now available.

  * AMI images are now produced in the vhdx format. This fixes
    the issue that those images couldn't be previously booted in EC2.

  * In version 10 the logs weren't saved when osbuild failed. This
    is now fixed.

  * The warnings when upgrading/removing the RPM package are now fixed.
    Note that updating to version 11 still produces them because
    the upgrade process runs also the scriptlets from version 10.

  * The size calculation for Fedora 31 vhd images is fixed.

  * The size field was removed from the tar assembler struct.
    The field has actually never been supported in osbuild
    and it doesn't make any sense.

  * The minimal required version of osbuild is bumped to 12.

  * This release also got big upgrades to the testing infrastructure,
    more tests are run on a CI and they now run faster. Also, the unit
    test coverage is improved.

  * The correct `metadata_expire` value is now passed to dnf. In the
    past, this led to a lot of failed builds, because dnf has the
    default expire time set to 48 hours, whereas the Fedora updates
    repos have the expire time of 6 hours.

  * A decision was made that the minimal Go version required for
    building the project is 1.12. This is now enforced by the CI.

  * The intermediate s3 object is now deleted after the upload to AWS
    is finished. It has no value for users.

  * The upload to AWS has now a bigger timeout. The current coronavirus
    situation is affecting the AWS responsiveness in a negative way.

  * The weldr API has better test coverage. In the process, several
    bugs in sources and composes were fixed.

  * Worker and jobqueue packages are receiving a big refactoring.
    This is the prerequisite for having multiple job queues for building
    images for different distributions and architectures.

  * The image tests now boot the AWS images in the actual EC2.

  * Fedora is now build with updates and modules repositories
    enabled, therefore up-to-date images are now produced.

  * A new man-page `osbuild-composer(7)` with high-level
    description of the project is now available. It can be built
    by the new man target in the Makfile.

  * All Fedora images have now a generic initramfs. This should
    make the images more reproducible and less likely failing to boot
    if the image build was done in a less usual environment.

  * Metalink is now used to access the Fedora repositories. This change
    should hopefully lead to more stable builds.

  * Composer is now released to Fedora 32 and 33 in a new
    osbuild-composer package. The old golang-github-osbuild-composer
    package will be automatically upgraded to the new one.

  * The internal osbuild-pipeline command now has a more user-friendly

  * The RCM API (in development, experimental) is reworked to allow
    any distribution-architecture-image type combination.

  * The work on a high-level description of image types began.
    See image-types directory.

  * The osbuild-worker arguments are reworked, they are now much more

  * The image-info tool used in the integration tests can be now run
    on Fedora 32.

  * The unit test coverage is now much bigger, thanks to all

  * Internal distribution representation is significantly reworked,
    this simplifies the process of adding the support for all currently
    missing architectures.

  * Integration tests were also improved, the image tests are fully
    switched to the new Go implementation and an automatic way
    of generating test cases is added. The weldr API coverage is also
    much better. Several bugs in it were fixed in the process.

  * is now used to monitor the test coverage of the code.

  * As always, minor fixes and improvements all over the place.

  * All generated pipelines now use the `org.osbuild.rpm` stage of
    osbuild, rather than `org.osbuild.dnf`. This improves on splitting
    resource acquisition from image building and should make image
    composition more reliable and faster.

  * The `STATE_DIRECTORY` environment variable now allows changing the
    state directory path of `osbuild-composer`. This is to support older
    systemd versions that do not pass in `StateDirectory=` to the service

  * Minor fixes and improvements all over the place.

  * Support for `RHEL 8.1` as image type is now available.

  * Semantic versioning of blueprints in the lorax API is now enforced.
    This was always the case for the original lorax API, and *Composer*
    now follows this as well.

  * Lots of internal improvements, including many automatic tests,
    improved error handling, better cache directory management, as well
    as preparations to move over from `org.osbuild.dnf` to
    `org.osbuild.rpm` in all build pipelines.
