-* Added the ability to blend a `Model` with a color/translucency. Added `color`, `colorBlendMode`, and `colorBlendAmount` properties to `Model`, `ModelGraphics`, and CZML. Added `ColorBlendMode` enum. [#4547](https://github.com/AnalyticalGraphicsInc/cesium/pull/4547)
-* Added the ability to render a `Model` with a silhouette. Added `silhouetteColor` and `silhouetteSize` properties to `Model`, `ModelGraphics`, and CZML. [#4314](https://github.com/AnalyticalGraphicsInc/cesium/pull/4314)
-* Added new `Label` properties `showBackground`, `backgroundColor`, and `backgroundPadding` to the primitive, Entity, and CZML layers.
-* Added new enum `VerticalOrigin.BASELINE`.  Previously, `VerticalOrigin.BOTTOM` would sometimes align to the baseline depending on the contents of a label.
-* Added support for newlines (`\n`) in Cesium `Label`s and CZML. [#2402](https://github.com/AnalyticalGraphicsInc/cesium/issues/2402)
-* Fixed tooltips for gallery thumbnails in Sandcastle [#4702](https://github.com/AnalyticalGraphicsInc/cesium/pull/4702)
-* Fixed `Rectangle.union` to correctly account for rectangles that cross the IDL [#4732](https://github.com/AnalyticalGraphicsInc/cesium/pull/4732).

+* Added `WebGLConstants` enum.  Previously, this was part of the private Renderer API. [#4731](https://github.com/AnalyticalGraphicsInc/cesium/pull/4731)
+* Fixed tooltips for gallery thumbnails in Sandcastle [#4702](https://github.com/AnalyticalGraphicsInc/cesium/pull/4702)
