+Make sure to read about the breaking changes and the release highlights below!
+
+#### Breaking changes
+
+If you are using chartpress to publish development releases should be aware that
+the suffix appended to chart versions and image tags is changed to look like
+`1.2.3-0.dev.git.n.hash`, where the following things has changed:
+
+- `-0.dev` is appended by default for non pre-release versions.
+- `n` is the number of commits on the branch, where it previously was the number
+  of commits since the last tag on the branch.
+
+#### Release highlights
+
+- The option `baseVersion` is added to chart configuration in chartpress.yaml,
+  for more details see the [README.md section on controlling development
+  versions](https://github.com/jupyterhub/chartpress#controlling-development-versions).
+
+#### New features added
