-## Announcement
+## Announcements
 
-At this point we have merged the next branch based on Debian Buster into master.
+1. Debian Buster is now Docker base image
-That means the docker image latest uses Buster. The change may break things!
+   - Filebeat was removed
-
+   - Dovecot was downgraded
-The following possibly breaking changes are known:
+2. ELK was removed
-
+3. New contributing guidelines were added
-- Filebeat is removed and should be handled by another container, see [Wiki](https://github.com/tomav/docker-mailserver/wiki/).
-- Dovecot will be downgraded a little bit (same major version) so that we can use the official Debian version.
-
-If you want to stick to the old version a while longer, either switch to stable or to a specific version.
-If you run into problems, please raise issues and ask for help. Don't forget to provide details.
