   #### ENHANCEMENTS
 
-  * **Significant performance improvements** to reduce p99 file sizes globally (-45%) at all zooms to under 200 kb, with some improvements for low-zoom p50 sizes. Changes include:  geometry simplification at low zooms, pushing some features like unclassified roads to the next zoom, dropping names on short lines and dropping other properties at mid-zooms to also allow more aggressive merges to multi-lines and multi-polygons, and more sophisticated handling of max zoom and overzoom tiles for buildings and addresses. Further reductions can be achieved by configuring [Tapalcatl](https://github.com/tilezen/tapalcatl) to selectively drop layers and name translations (eg to drop `earth` and `transit` layers or only keep English and Urdu names) depending on your business needs. _Chart shows sizes in kilobytes, based on commonly requested top 100,000 tiles at 512 pixel zooms. NOTE: all other zooms in this document use nominal 256 pixel zooms, offset by 1)._

   * **Internationalization** is now feature complete by extending disputed boundary point-of-view handling fully into mid- and high-zooms with extensive paired data edits upstream in OpenStreetMap, using Natural Earth as a sanity check for country names, and consideration of common and less common edge cases, including [Taiwan](https://en.wikipedia.org/wiki/Wikipedia:Naming_conventions_(Chinese)/Taiwan) and [Somaliland](https://en.wikipedia.org/wiki/Somaliland).
   * **MapLibre support** with buffered tiles and connivence properties like pre-calculating shield text length allow Tilezen tiles to more easily be styled in [MapLibre](https://github.com/maplibre/maplibre-gl-js) and [MapboxGL](https://github.com/mapbox/mapbox-gl-js), thus extending support beyond [Tangram](https://github.com/tangrams/tangram).
   * **boundaries**: Add disputed boundary line point-of-view (POV) for mid- and high-zoom features sourced from OpenStreetMap (OSM), including extensive upstream editing in OSM to match Natural Earth's low-zoom disputed area modeling in earlier releases. New `unrecognized_dispute` kind and `disputed_by` property. (Issue [#1901](https://github.com/tilezen/vector-datasource/issues/1901))
