  - new: actually renames items in the "unaccounted renames" dialog
  - new: link to monotone manual from the help menu (FS#23)
  - improved: lighter, more eye-friendly colors for diff views (FS#24)
+ - bugfix: the changeset browser is now able to browse branches with no
+   hierarchical history (i.e. zero ancestors) (FS#29)
  - bugfix: guitone no longer considers the workspace to be invalid if the last
    file is physically removed from it. Also, the amount of inventory reloads
    has been lowered since we only notify about changed paths every 500ms
