 Apptools CHANGELOG
 ==================
 
+Version 5.0.0
+~~~~~~~~~~~~~
+
+Released : DD MM YYYY
+
+This is a major release mainly relating to code modernization. In this release,
+support for Python versions < 3.6 have been dropped. Numerous dated
+sub-packages and code fragments have been removed. Additionally, there were
+various fixes and documentation updates.
+
+Fixes
+-----
+* Fix SyntaxWarning in persistence.file_path (#116)
+* Fix container items change event being saved in preferences (#196)
+* Fix synchronizing preference trait with name *_items (#226)
+
+Deprecations
+------------
+* Deprecate apptools.undo subpackage (undo was moved to pyface) (#250)
+
+Removals

+* Remove ``lru_cache`` subpackage (#184)
+* Remove support for Python 2.7 and 3.5 (#190)
+* Remove the ``apptools.sweet_pickle`` subpackage.  Note that users of
+  sweet_pickle can in some cases transition to using ``apptools.persistence``

+  remove ``apptools.type_manager`` entirely.  Finally, remove
+  ``apptools.naming.adapter``. (#219)
+* Remove ``apptools.persistence.spickle`` submodule (#220)
+* Remove ``apptools.naming.ui`` sub package (#233)
+
