+
+At long last, we are proud to announce the first alpha release of OpenLP 3.0!
+
+The biggest new feature in version 3.0 is the new renderer. Still based in HTML, but using the new Chrome-based
+QtWebEngine component, it should deliver much better performance, and it also enables us to offer something people have
+been requesting for a long time: transitions!
+
+    But the wheat and the spelt were not ruined, for they ripen late.
+
+    Exodus 9:32
+
+.. warning::
+   This is a preview of the next version of OpenLP. It is unstable, there are bugs, it will crash. DO NOT use it on any
+   system you need to depend on. We cannot be held responsible for your data loss. Once you have installed OpenLP 3.0,
+   your data will be upgraded, and you will be unable to return to OpenLP 2.4.6. Do not upgrade unless you are sure you
+   don't need version 2.4.6 any more. This version of OpenLP will overwrite your current installation.
