 ### ✨ Features and improvements
-- Aligned the implementation of `["geometry-type"]` with [its spec](https://maplibre.org/maplibre-style-spec/expressions/#geometry-type). Now, when applicable, `["geometry-type"]` returns values not available while using `"$type"`: `"MultiPoint"`, `"MultiLineString"`, and `"MultiPolygon"`. The behaviour of `"$type"` has not changed. ([#519](https://github.com/maplibre/maplibre-style-spec/pull/519))
