+## [2.0.0] - 2023-09-09
+
+### Added
+
+- Introduced the `Preprocessor` enum with the following options: `None`, `COM`, and `PCA`. This enum replaces the previous transformation settings (`UseLocalTransformation`/`UsePCATransformation`).
+- Introduced the `Status` (with values `OK`, `ERR`) enum along with corresponding native data. This enum is now utilized for input validation, with functionality extending beyond the Unity editor to encompass validation in builds as well.
+- Added a benchmark test for mesh refinement, which will be used for future performance measurement.
+
+### Changed
+
+- Default values for `TriangulationSettings`.
+- Updated Unity Editor to version `2022.2.1f1`.
+- Bumped dependencies: Burst to `1.8.7`, Collections to `2.2.0`.
+
+### Removed
+
+- Removed the following deprecated methods: `Schedule(NativeArray<float2>, ...)`.
+- Removed the following deprecated properties: `Positions`, `Triangles`, `PositionsDeferred`, `PositionsDeferred`.
+- Removed the internal `TriangulatorNativeData` as part of a significant refactor to simplify the code structure. Internal implementations were cleaned up, and code structure was simplified.

 ## Dependencies
 
 - [`Unity.Burst`][burst]
 - [`Unity.Collections`][collections]
 
-## Roadmap v2.0
+## Things to consider
 
-- [ ] Cache circles for constraint edges.
-- [ ] Update `edgeToTriangles` buffer instead rebuilding.
-- [ ] Update default `Setting`.
-- [ ] Remove native data `struct` (move logic to jobs).
-- [X] ~~Remove obsoletes.~~
-- [X] ~~Bump packages and editor.~~
-- [X] ~~Introduce state to support runtime (build) validation.~~
-- [X] ~~"Extract" transformations.~~
+- [ ] Consider using BVT (or another data structure) to accelerate computing.
+- [ ] Consider caching circles for constraint edges.
+- [ ] Consider refactoring the data structure to update the `edgeToTriangles` buffer instead of rebuilding it.
