+### Added
+- clear timers from task timeouts to remove them from the event loop: this is helpful to clear up resources for long-running timeouts and fastly resolving tasks. If not cleared, the timeouts stay in the event loop until they’re due
+- add keep error handler when calling `pool.handleError` after `pool.for`: previously the error handler was lost
+
+### Updated
+- bump dependencies
