 - Simplified worker task logic by avoiding an explicit event loop - [pull #95][issue95]
 - Fixed an issue in `WindowsPath`, where an empty path was converted to "/" when cast to another path type - [pull #91][issue91]
 - Fixed two hang issues in `TaskPool` causing the worker task processing to possibly hang at shutdown or to temporarily hang during run time - [pull #96][issue96]
+- Fixed internal timer callback tasks leaking memory - [issue #86][issue86], [pull #98][issue98]
