 ### 🐞 Bug fixes
 
+- Fix holes at the poles when terrain is used with globe ([#5232](https://github.com/maplibre/maplibre-gl-js/pull/5232))
+- Fix geometry artifacts when globe terrain is zoomed out too much ([#5232](https://github.com/maplibre/maplibre-gl-js/pull/5232))
 - _...Add new stuff here..._
