6.3.0

With more than 70 pull requests, this release not only brings significant improvements to the API documentation. It also fixes some old bugs and brings frequently requested improvements. And good news for TypeScript users: OpenLayers now ships with type definitions in .d.ts files.

New features and improvements

Several improvements to the Graticule layer, like consistent labeling, no more missing graticule lines, and it now works for views that cross the date line.
Better support for KML icon colors, as well as fills and outlines in PolyStyle
Better ol/Overlay performance and support for panning off-screen overlays into view
Most of the rendering code can now be run in web workers, e.g. to render to an OffscreenCanvas
OpenLayers now works fine in web components with shadow root
WebGL point layers now support rotation based on feature attributes
