+### Unreleased
+
+ - `Loop::set()` replaces the current driver with a dummy driver for the time of `gc_collect_cycles()` now. This allows cyclic references to be cleaned up properly before the new driver is set. Without such a fix, cyclic references might have been cleaned up later, e.g. cancelling their watcher IDs on the new loop, thereby cancelling the wrong watchers.
+
 ### 2.0.2
 
  - Fixed warnings and timers in `EventDriver`.
