• Changed – Query time from storage in recurring and delayed schedulers when supported by storage.
• Changed – Move job to the `DeletedState` instead of `SucceededState` when its invocation was canceled by a filter.
• Changed – Speedup delayed jobs when a custom default queue is specified by avoiding extra state transition.
• Changed – Use UI culture from `CurrentCulture` parameter when `CurrentUICulture` one is missing.
