 * Breaking changes
    * Corrected spelling of `Color.FUCHSIA` from `Color.FUSCHIA`. [#4977](https://github.com/AnalyticalGraphicsInc/cesium/pull/4977)
    * The enums `MIDDLE_DOUBLE_CLICK` and `RIGHT_DOUBLE_CLICK` from `ScreenSpaceEventType` have been removed. [#5052](https://github.com/AnalyticalGraphicsInc/cesium/pull/5052)
+   * Removed the function `GeometryPipeline.computeBinormalAndTangent`. Use `GeometryPipeline.computeTangentAndBitangent`. [#5053](https://github.com/AnalyticalGraphicsInc/cesium/pull/5053)
 * Added support to `DebugCameraPrimitive` to draw multifrustum planes. The attribute `debugShowFrustumPlanes` of `Scene` and `frustumPlanes` of `CesiumInspector` toggles this. `FrameState` has been augmented to include `frustumSplits` which is a `Number[]` of the near/far planes of the camera frustums.
 * Enable rendering `GroundPrimitives` on hardware without the `EXT_frag_depth` extension; however, this could cause artifacts for certain viewing angles.
 * Always outline KML line extrusions so that they show up properly in 2D and other straight down views.
