 # OSBuild - Build-Pipelines for Operating System Artifacts
 
+## CHANGES WITH 28:
+
+ * Add a new option to the `org.osbuild.qemu` assembler that controls
+   the qcow2 format version (`qcow2_compat`).
+
+ * Add history entries to the layers of OCI archives produced by the
+   `org.osbuild.oci-archive` stage. This fixes push failures to quay.io.
+
+ * Include only a specific, limited set of xattrs in OCI archives produced by
+   the `org.osbuild.oci-archive` stage. This is specifically meant to exclude
+   SELinux-related attributes (`security.selinux`) which are sometimes added
+   even when invoking  `tar` with the `--no-selinux` option.
+
+ * The package metadata for the `org.osbuild.rpm` stage is now sorted by
+   package name, to provide a stable sorting of the array independent of
+   the `rpm` output.
+
+ * Add a new runner for Fedora 35 (`org.osbuild.fedora35`) which is
+   currently a symlink to the Fedora 30 runner.
+
+ * The `org.osbuild.ostree` input now uses `ostree-output` as temporary
+   directory and its description got fixed to reflect that it does
+   indeed support pipeline and source inputs.
+
+ * devcontainer: Include more packages needed for the Python extension and
+   various tools to ease debugging and development in general. Preserve
+   the fish history across container rebuilds.
+
+ * Stage tests are writing the prodcued metadata to `/tmp` so the actual
+   data can be inspected in case there is a deviation.
+
+ * CI: Start running images tests against 8.4 and execute image_tests directly
+   from osbuild-composer-tests. Base CI images have been updated to Fedora 33.
