10.9.0

In the 10.9 release, GeoZarr and GeoTIFF support saw major improvements — including multi-group band support, per-band metadata, and more efficient tile loading. WebGL rendering precision and performance were enhanced, and several vector rendering, hit detection, and trackpad zoom interaction issues were resolved.
