  * Implement `Membrane.Debug.Filter` and `Membrane.Debug.Sink`. [#552](https://github.com/membraneframework/membrane_core/pull/552)
  * Add `:pause_auto_demand` and `:resume_auto_demand` actions. [#586](https://github.com/membraneframework/membrane_core/pull/586)
  * Send `:end_of_stream`, even if it is not preceded by `:start_of_stream`. [#557](https://github.com/membraneframework/membrane_core/pull/577)
+ * Fix process leak in starting clocks. [#594](https://github.com/membraneframework/membrane_core/pull/594)
  
 ## 0.11.0
  * Separate element_name and pad arguments in handle_element_{start, end}_of_stream signature [#219](https://github.com/membraneframework/membrane_core/issues/219)
