 Changes
 -------
 
+##### 5.0.0 - 2022-04-30
+
+* Move namespace from T0* to T2* to avoid collision with other library using same error code.
+* Remove python 2 specific code paths, error messages and six usage.
+
 ##### 4.0.1 - 2022-04-30
 
 * Fixing bug with noqa detection by removing manual detection and relying on flake8 itself.
