v4.0.2

Fix handling of features with empty coordinates — treat them the same way as features with null geometry (as per the spec).

v4.0.1

Fix issues in some ESM setups because of an incorrect exports field in package.json.

v4.0.0

• ⚠️ Breaking: drop CommonJS entry point and switch to ESM only for Node & bundlers + UMD bundle for browsers. #180
• ⚠️ Breaking: drop support for IE11 (you can still transpile on your end to keep it). #180
• Fix a rare edge case that could potentially lead to stack overflow by @district10 in #173 and @mlptownsend in #176
• Small performance optimizations by @vicb in #133, #132, #135
• Force getTile arguments as number by @andrewharvey in #128
• Fix a minor bug in tiling code by @CraigglesO in #130

v3.2.0

• Add generateId option for automatically filling feature id property (populating it with the index of the feature in a feature collection).
• Add promoteId option for filling feature id with a value from a specific feature property.

v3.1.4

• Fix handling of features with id of 0. #107
• Minor fix for degenerate inputs.

v3.1.3

Fixed a bug which caused a "max call stack size" error on certain degenerate input. #105

v3.1.2

Fixed a bug with lineMetrics: true and MultiLineString geometries where only the first line was processed.

v3.1.1

Fixed inconsistent clipping of features on tile boundary when buffer = 0. #102

v3.1.0

• Added experimental lineMetrics: true option that adds mapbox_clip_start and mapbox_clip_end properties to all line features in the generated tiles, indicating which part of the original full line each feature represents.
• Turned GeoJSON-VT into a proper ES module (so you can do import geojsonvt from 'geojson-vt' in supported environments).

v3.0.0

• Massively improved performance. Index now takes ~2x less memory and generating tiles is overall 20% to 100% faster (with bigger gains on heavier datasets).
• Removed "clipped square" heuristics (they were complicating the codebase without a noticeable performance gain).
• Added a descriptive error when passing zoom higher than 24.
• Added TopoJSON support to the demo page.
