 # Release notes
 
+## [v3.3.13](https://github.com/mdn/browser-compat-data/releases/tag/v3.3.13)
+
+July 29, 2021
+
+### Notable changes
+
+- `api.MediaDevices.stereo_audio_capture` was removed because it was historic, incomplete, and impractical to fix. ([#11717](https://github.com/mdn/browser-compat-data/pull/11717))
+
+- A catch-all mixin feature, `api.HTMLFrameSetElement.event_handlers`, has been removed. Read [#11675](https://github.com/mdn/browser-compat-data/issues/11675) for progress on the long-term fix of representing the `WindowEventHandlers` mixin's exposed interfaces. ([#11459](https://github.com/mdn/browser-compat-data/pull/11459/))
+

+
+  - `api.ConstrainBoolean` ([#11000](https://github.com/mdn/browser-compat-data/pull/11000))
+  - `api.ConstrainDOMString` ([#11000](https://github.com/mdn/browser-compat-data/pull/11000))
