6.4.0

With more than 120 pull requests, this release brings a facelift of the website, as well as many bug fixes and several exciting new features.

Upgrade notes

Pointer events polyfill removed

Now that all major browsers support Pointer events natively, we removed the elm-pep dependency. If you are targeting older browsers that do not support Pointer events, you now need to include a pointer events polyfill (elm-pep or pepjs) in your application.

New features and improvements

Several event handling fixes and improvements for seamless integration into scrollable web pages and improved support for maps in web components.
Map interactions work again when ol.css is not included in the build.
More stable map views with decluttered labels during panning.
Image smoothing can be disabled, so raster cells can have sharp edges in image layers now.
Better cache management for tile layers.
Retina/HiDPI support for regular shape and svg icon styles.
