+  The advantage of these identifiers is that they are less prone to changes when
   something changes in the todo.txt file. For example, identifiers are much more
   likely to remain the same when completing a todo item (and archiving it). With
   linenumbers, all todo items below the completed one would get a new
   identifier.
+* Relative dates with months and years are more accurate now (thanks to Jacek
+  Sowiński).
 * Added option to automatically add the projects of the parent todo item when
   adding a child todo item. Enable append_parent_projects in topydo.conf.
+* `topydo help` shows a list of available subcommands. Moreover, you can run
+  `topydo help <subcommand>` as well.
+* Let setuptools provide a `topydo` executable.
+* Various other fixes.
