 * MGLMapDebugOverdrawVisualizationMask no longer has any effect in Release builds of the SDK. This debug mask has been disabled for performance reasons. ([#5555](https://github.com/mapbox/mapbox-gl-native/pull/5555))
 * Fixed a typo in the documentation for the MGLCompassDirectionFormatter class. ([#5879](https://github.com/mapbox/mapbox-gl-native/pull/5879))
 
+## 3.3.5 - November 2, 2016
+
+* Speculatively fixed an OpenGL rendering crash. ([#6844](https://github.com/mapbox/mapbox-gl-native/pull/6844))
+* Fixed an issue with symbols not being properly stripped from the dynamic framework. The dSYM file included with the standard dynamic framework in previous releases (e.g., `mapbox-ios-sdk-3.3.4-dynamic.zip` or the `Mapbox-iOS-SDK` pod) could not be used to symbolicate crashes. ([#6531](https://github.com/mapbox/mapbox-gl-native/pull/6531))
+* Include simulator architecture slices in the dSYM file that is generated for release builds. ([#5740](https://github.com/mapbox/mapbox-gl-native/pull/5740))
+* Fixed a rare networking-related crash. ([#5932](https://github.com/mapbox/mapbox-gl-native/pull/5932))

 ## 3.3.4 - August 8, 2016
 
 * Fixed an issue that caused the user dot to be selected when tapping an annotation that lies within the user dot’s accuracy circle. First attempt was [#5816](https://github.com/mapbox/mapbox-gl-native/pull/5816) in v3.3.2, which excluded the pulsing halo but not the accuracy circle. ([#5894](https://github.com/mapbox/mapbox-gl-native/pull/5894))
