The 8.0 release brings several API simplifications. Some of them are not backwards compatible, so make sure to read the upgrade notes. The new StadiaMaps source replaces the Stamen source, because Stamen no longer hosts map tiles. Several WebGL improvements are also part of this release. And finally, a new loader API for image layers makes working with non-tiled raster data more modular and faster.
