++   v0.7.6 Incorporates [Sietse's work](https://github.com/sietse/todo.txt-vim/commit/57d45200c8b033d31c9191ee0eb0711c801cdb1d) to make cancel and mark as done mapping repeatable using [vim-repeat](https://github.com/tpope/vim-repeat).
-update your vimrc (see [completion](#completion)).
++   v0.7.5 Incorporates [Fievel's work](https://github.com/fievel/todo.txt-vim/commit/0863e1434e9a89ace06c4856b6cb32ba9906e3de) to make overduedates work on python3.
++   v0.7.4 includes the overduedate support from Guilherme Victal (see pull
+
+    [request #45 on freitass version](https://github.com/freitass/todo.txt-vim/pull/45)),
+    it highlight dates in overdue tasks as an Error. It depends on a
+    Python library, however, and as such will only be able to work if your version
+    of Vim was compiled with the `+python` option (as most common versions do).
+ 
+    If your Vim installation does **not** have Python support, this plugin **will work just fine** but this feature will be disabled.
