 =========
 
-10.3.1 - in progress
+10.3.2 - in progress
+--------------------
+
+  * next: remove duplicated targets when updating from an unstable changeset

   * next: when some potential targets are unstable, ask user which changeset
     they want to update to (only mixing stable and unstable when --evolve flag
     is given, which is the default)
 
+  * packaging: default to using Python 3 in Makefile
+
+topic (0.22.1)
