+This is a new automatic release of Mailu. The new version can be seen in the tag name.
+The main version X.Y (e.g. 1.8) will always reflect the latest version of the branch. To update your Mailu installation simply pull the latest images `docker-compose pull && docker-compose up -d`.
+The pinned version X.Y.Z (e.g. 1.8.1) is not updated. It is pinned to the commit that was used for creating this release. You can use a pinned version to make sure your Mailu installation is not suddenly updated when recreating containers. The pinned version allows the user to manually update. It also allows to go back to a previous pinned version.
+
+To check what was changed:
+- Go to https://github.com/Mailu/Mailu/tree/master/towncrier/newsfragments
+- Change the branch to the tag of this release.
+- Read the news fragment files to check what was changed.
+
+The release notes of the original release can be accessed via menu item 'Release notes' on [mailu.io](https://mailu.io/).

+Use semantic versioning for building releases.
+- Add versioning (tagging) for branch x.y (1.8). E.g. 1.8.0, 1.8.1 etc.
+  - docker repo will contain x.y (latest) and x.y.z (pinned version) images.
+  - The X.Y.Z tag is incremented automatically. E.g. if 1.8.0 already exists, then the next merge on 1.8 will result in the new tag 1.8.1 being used.
+- Make the version available in the image.
+  -  For X.Y and X.Y.Z write the version (X.Y.Z) into /version on the image and add a label with version=X.Y.Z
+	  -  This means that the latest X.Y image shows the pinned version (X.Y.Z e.g. 1.8.1) it was based on. Via the tag X.Y.Z you can see the commit hash that triggered the built.
+  -  For master write the commit hash into /version on the image and add a label with version={commit hash}
+-  Automatic releases. For x.y triggered builts (e.g. merge on 1.9) do a new github release for the pinned x.y.z (e.g. 1.9.2). 
+  -  Release shows a static message (see RELEASE_TEMPLATE.md) that explains how to reach the newsfragments folder and change the branch to the tag (x.y.z) mentioned in the release. Now you can get the changelog by reading all newsfragment files in this folder.

Subject: [PATCH 2/9] Process code review remarks - Moved run to bottom of
 Dockerfile to allow using unmodified / cached states. - Simplified bash code
 in deploy.sh. - Improved the large bash one-liner in CI.yml. It could not
 handle >9 for 1.x.
