 ### dev-v2 (not yet released)
 
 *   Core library:
-    *   `LoadControl`:
-        *   Add a `targetLiveOffsetUs` parameter to `shouldStartPlayback`.
+    *   Add a `LivePlaybackSpeedControl` component to control the playback speed
+        during live playbacks. This allows the player to stay close to the
+        configured live offset. A configurable default implementation
+        `DefaultLivePlaybackSpeedControl` is added to `ExoPlayer` and
+        `SimpleExoPlayer` by default.
+    *   Add `LiveConfiguration` to `MediaItem` to allow media-specific live
+        offset and live playback speed settings. The same settings can be set
+        for all `MediaItems` in `DefaultMediaSourceFactory`.
+    *   Add  `targetLiveOffsetUs` parameter to
+        `LoadControl.shouldStartPlayback`.
     *   Verify correct thread usage in `SimpleExoPlayer` by default. Opt-out is
         still possible until the next major release using
         `setThrowsWhenUsingWrongThread(false)`
