 - Rebased MIB importing code onto `importlib` because `imp` is long
   deprecated
-- MIB objects resolution made more forgiving to errors, added optional

+- Received MIB objects resolution made more forgiving to errors, added
+  optional `ignoreErrors` parameter to `ObjectType.resolveWithMib()` to
+  control that behaviour.
 - Fixed asyncore main loop to respect non-default timer resolution
 - Fixed `.setTimerResolution()` behaviour of abstract main loop dispatcher
   to update call intervals of the existing periodic dispatcher jobs
