 # koji-osuild  - Koji and OSBuild integration
 
+## CHANGES WITH 3:
+
+  * Ship tests in koji-osbuild-tests package. The tests got
+    reworked so that they can be installed and run from the
+    installation. This will be useful for reverse dependency
+    testing, i.e. testing the plugins from other projects,
+    like composer as well as in gating tests.
+
+  * Add the ability to skip the tagging. An new command line
+    option, `--skip-tag` is added, which translate into an
+    a new field in the options for the hub and builder. If
+    that option is present, the builder plugin will skip the
+    tagging step.
+
+  * builder plugin: the compose status is attached to the
+    koji task as `compose-status.json` and updated whenever
+    it is fetched from composer. This allows to follow the
+    individual image builds.
+
+  * builder plugin: The new logs API, introduce in composer
+    version 24, is used to fetch and attach build logs as
+    well as the koji init/import logs.
+
+  * builder plugin: Support for the dynamic build ids, i.e.
+    don't use the koji build id returned from the compose
+    request API call but use the new `koji_build_id` field
+    included in the compose status response.
+    This makes koji-osbuild depend on osbuild composer 24!
+
+  * test: lots of improvements to the tests and ci, e.g.
+    using the quay mirror for the postgres container or
+    matching the container versions to the host.
