 * `Transforms.headingPitchRollToFixedFrame` and `Transforms.headingPitchRollQuaternion` now take a `HeadingPitchRoll` object in addition to separate heading, pitch, and roll values.  Separate values will be deprecated in 1.30.
 * Prevent execution of default device/browser behaviour when handling "pinch" touch event/gesture.
 * Fixed a crash when zooming from touch input on viewer initialization. [#4177](https://github.com/AnalyticalGraphicsInc/cesium/issues/4177)
