 Changelog
 =========
 
+6.1.0 - in progress
+-------------------
+
+ - improve message about obsolete working copy parent,
+ - improve message issued  when accessing hidden nodes,
+ - add a 'experimental.auto-publish' config. Set it so 'warn' to get a warning
+   when a push is publishing some draft changesets and 'abort' to prevent that
+   to happen at all.
 
 6.0.2 - in progress
