 ## Release notes
 
+v0.7.4 includes the overduedate support from Guilherme Victal, it highlight
+dates in overdue tasks as an Error (as suggested on issue
+[#44][https://github.com/freitass/todo.txt-vim/issues/44]). 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.
+
+
 Since v0.7.3, `TodoComplete` is replaced by `todo#Complete`, you might need to
 update your vimrc (see [completion](#completion)).
