- **added** — Add support for `symbol-height-offset` and `symbol-height-anchor` layout properties, which raise icons and text above the map, with `symbol-height-anchor` selecting whether the offset is measured from the terrain surface (ground, the default) or from the zero elevation datum (absolute)
- **changed** — Pick terrain coordinates with a CPU raycast against the DEM instead of a coords framebuffer readback, achieving full DEM resolution, eliminating GPU stalls on pointer events, and reducing GPU memory usage by approximately 4MB
- **fixed** — Fix labels briefly appearing too large when zooming out several levels at once with a zoom-dependent `text-size` or `icon-size`
- **fixed** — Fix globe tile selection measuring distances from the ground point below the camera instead of the camera itself, refining some views past the requested zoom and leaving others coarser
- **fixed** — Fix the style's `center`, `zoom`, `bearing`, `pitch` and `roll` being ignored when the map was created with a `minZoom` or `minPitch` option
- **fixed** — Upload the `color-relief` DEM texture once per tile instead of on every frame

###### ✨ Features and improvements

- Add support for `symbol-height-offset` and `symbol-height-anchor` layout properties, which raise icons and text above the map. `symbol-height-anchor` selects whether the offset is measured from the terrain surface (`ground`, the default) or from the zero elevation datum (`absolute`) ([#7827](https://github.com/maplibre/maplibre-gl-js/pull/7827)) (by [@HarelM](https://github.com/HarelM))
- Pick terrain coordinates with a CPU raycast against the DEM instead of a coords framebuffer readback: full DEM resolution, no GPU stall on pointer events, and about 4MB less GPU memory ([#7640](https://github.com/maplibre/maplibre-gl-js/issues/7640)) (by [@johncarmack1984](https://github.com/johncarmack1984))

###### 🐞 Bug fixes

- Fix labels briefly appearing too large when zooming out several levels at once (e.g. a scroll-wheel or pinch fling) with a zoom-dependent `text-size`/`icon-size` ([#8175](https://github.com/maplibre/maplibre-gl-js/pull/8175)) (by [@mondsichtung](https://github.com/mondsichtung))
- Fix globe tile selection measuring distances from the ground point below the camera instead of the camera itself, refining some views past the requested zoom and leaving others coarser ([#8187](https://github.com/maplibre/maplibre-gl-js/pull/8187)) (by [@Alchez](https://github.com/Alchez))
- Fix the style's `center`, `zoom`, `bearing`, `pitch` and `roll` being ignored when the map was created with a `minZoom` or `minPitch` option, since applying those limits marked the transform as modified ([#5932](https://github.com/maplibre/maplibre-gl-js/issues/5932))
- Upload the `color-relief` DEM texture once per tile instead of on every frame ([#8209](https://github.com/maplibre/maplibre-gl-js/pull/8209))
