 * Fixed an issue where models would cause a crash on load if some primitives were Draco encoded and others were not. [#7383](https://github.com/AnalyticalGraphicsInc/cesium/issues/7383)
 * Fixed Node.js support for the `Resource` class and any functionality using it internally.
 * Fixed an issue where some ground polygons crossing the Prime Meridian would have incorrect bounding rectangles. [#7533](https://github.com/AnalyticalGraphicsInc/cesium/pull/7533)
+* Fixed an issue where polygons on terrain using rhumb lines where being rendered incorrectly. [#7538](https://github.com/AnalyticalGraphicsInc/cesium/pulls/7538)
