+### 1.58 - 2019-06-03
 
 ##### Additions :tada:
 * Added support for new `BingMapsStyle` values `ROAD_ON_DEMAND` and `AERIAL_WITH_LABELS_ON_DEMAND`. The older versions of these, `ROAD` and `AERIAL_WITH_LABELS`, have been deprecated by Bing. [#7808](https://github.com/AnalyticalGraphicsInc/cesium/pull/7808)
 * Added syntax to delete data from existing properties via CZML. [#7818](https://github.com/AnalyticalGraphicsInc/cesium/pull/7818)
 * `BingMapsImageryProvider` now uses `DiscardEmptyTileImagePolicy` by default to detect missing tiles as zero-length responses instead of inspecting pixel values. [#7810](https://github.com/AnalyticalGraphicsInc/cesium/pull/7810)
 
+##### Fixes :wrench:
+* Fixed an edge case where Cesium would provide ion access token credentials to non-ion servers if the actual asset entrypoint was being hosted by ion. [#7839](https://github.com/AnalyticalGraphicsInc/cesium/pull/7839)
