 Version 0.3
 ===========
 
-**In Development**
+This release includes a number of bug fixes and enhancements related to hypothesis testing with decision trees.
+Moreover, we have added an experimental multi-view decision tree / random forest, which considers multiple views
+of the data when building trees. The documentation page has also undergone an organizational overhaul
+making it easier for users to find examples related to specific use cases.
