+h2. Version 4.0.0
+* Drop support for Python 2, hence the version bump. Update list of PY3K versions to currently-supported versions. If you need to use textile on Python 2.7 or Python 3.3 or 3.4, please use textile Version 3.0.4.
+* For use in PyPy environments, textile used to work well with the regex package. Lately, it's running into trouble. Please uninstall regex if this is the case for you.

 h2. Version 3.0.4
