 * Fixed a bug when creating billboard and model entities without a globe. [#6109](https://github.com/AnalyticalGraphicsInc/cesium/pull/6109)
 * Added support for vertex shader uniforms when `tileset.colorBlendMode` is  `MIX` or `REPLACE`. [#5874](https://github.com/AnalyticalGraphicsInc/cesium/pull/5874)
-* Added `shouldAnimate` option to the `Viewer` constructor to indicate if the clock should begin animating immediately.[#6154](https://github.com/AnalyticalGraphicsInc/cesium/pull/6154)
+* Fixed a bug that could cause tiles to be missing from the globe surface, especially when starting with the camera zoomed close to the surface.
