The 10.8 release brings new sources: OGCMap for OGC API Maps, and an experimental GeoZarr source for raster data conforming to the evolving GeoZarr specification. Vector rendering also gets an important new feature: finally, we can offset lines. And we have added support for ReferrerPolicy when fetching source data and icons, which may become important because OpenStreetMap already started demanding a referer header when serving tiles. To round up the release, many bugs were fixed, and memory management for image styles was improved.
