 CHANGELOG
 =========
 
-This branch supports Ubuntu 18.04 **only**. When upgrading, **always** upgrade your **existing** Ubuntu 14.04 machine to version the latest release supporting Ubuntu 14.04 --- v0.28. If you are running an older version of Mail-in-a-Box which has an old version of ownCloud or Nextcloud, you will *not* be able to upgrade your data because older versions of ownCloud and Nextcloud that are required to perform the upgrade *cannot* be run on Ubuntu 18.04.
-

+This is the first release for Ubuntu 18.04. Mail-in-a-Box can now **only** be installed on Ubuntu 18.04.
