-This is a new function and bug fix release. We continue the action "Bacula for
-Everybody!" for making first contact with Bacula easier for new users and this
-time we prepared a new file storage wizard. It enables to create both single
-storage devices and multi-device autochangers as well.
+Bacularis 4.2.0 introduces support for a plugin interface on the API side.
+So, since now users are able to create own API-side plugins in the same way
+as they can already create Web-side plugins. For a good start we provided
+a Bacula configuration plugin interface and we prepared first API plugin for
+attaching pre/post config actions.
 
-Second significant change is support for plugins. This is a friendly plugin
-interface to easily extend Bacularis for new functions. The first step in this
-feature is support for the web interface plugins. To prepare a plugin you will
-need a bit of knowledge about PHP language and object-oriented programming. If
-you are not strong PHP programmer, don't worry, it is really simple interface
-to create new plugins. We also prepared two first plugins: for e-mail
-notifications and for Mattermost notifications.
+On the Bacula deployment side, we extended support for Bacula packages from
+bacula.org. It significantly simplifies configuring OS profiles to use
+bacula.org packages. It causes that using system Bacula packages, packages
+from bacula.org or packages provided in self-hosted package repository can
+easily be configured in the OS profile.
 
-Finally, we would like to thank the entire Community for bug reports, ideas and
-for being active. With your involvement we can much more.
+This version is also bug fix release. We fixed couple of bugs found in
+the deployment function.
