 ### Added
 
+- Added new frames `FrameProcessorPauseFrame` and `FrameProcessorResumeFrame`
+  which allow pausing and resuming frame processing for a given frame
+  processor. These are control frames, so they are ordered. Pausing frame
+  processor will keep old frames in the internal queues until resume takes
+  place. Frames being pushed while a frame processor is paused will be pushed to
+  the queues. When frame processing is resumed all queued frames will be
+  processed in order. Also added `FrameProcessorPauseUrgentFrame` and
+  `FrameProcessorResumeUrgentFrame` which are system frames and therefore they
+  have high priority.
+
 - Added a property called `has_function_calls_in_progress` in
   `LLMAssistantContextAggregator` that exposes whether a function call is in
   progress.
