Cesium Version 1.24 Released


We are happy to announce the release of Cesium 1.24. This is a bug fix release after a big Cesium 1.23 release. It is especially worth upgrading if you care about leap seconds as much as we do, as a new leap second was added for December 31, 2016.

Also, MapQuest recently discontinued their support for direct tile access, so we removed MapQuest OpenStreetMap from the list of demo base layers. See the MapQuest Developer Blog for details.

For the full list of changes, see the change log.
