 ### 1.29 - 2017-01-02
 
-* 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).
+* Improved 3D Models
+   * Added the ability to blend a `Model` with a color/translucency. Added `color`, `colorBlendMode`, and `colorBlendAmount` properties to `Model`, `ModelGraphics`, and CZML. Also 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 support for newlines (`\n`) in Cesium `Label`s and CZML. [#2402](https://github.com/AnalyticalGraphicsInc/cesium/issues/2402)
 * Fixed texture rotation for `RectangleGeometry` [#2737](https://github.com/AnalyticalGraphicsInc/cesium/issues/2737)
+* Fixed translucency in Firefox 50. https://github.com/AnalyticalGraphicsInc/cesium/pull/4762
+* Fixed a bug that caused `GroundPrimitive` to render incorrectly on systems without the `WEBGL_depth_texture` extension. [#4747](https://github.com/AnalyticalGraphicsInc/cesium/pull/4747)
+* Fixed default Mapbox token and added a watermark to notify users that they need to sign up for their own token.
+* Fixed a bug that could cause a "readyImagery is not actually ready" exception with some configurations of imagery layers.
+* Fixed `Rectangle.union` to correctly account for rectangles that cross the IDL [#4732](https://github.com/AnalyticalGraphicsInc/cesium/pull/4732).
 * Added `divideComponents` function to `Cartesian2`, `Cartesian3`, and `Cartesian4`. [#4750](https://github.com/AnalyticalGraphicsInc/cesium/pull/4750)
 * 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)
 * Added compressed texture support. The supported extensions are `WEBGL_compressed_s3tc`, `WEBGL_compressed_texture_pvrtc`, and `WEBGL_compressed_texture_etc1`. [#4758](https://github.com/AnalyticalGraphicsInc/cesium/pull/4758)
