 ## [Unreleased]
 
+## [0.2.0] - 2026-03-05
+
+### Added
+- Added `axallocator = "0.2"` as a dependency
+
+### Changed
+- `AllocError`, `AllocResult`, `BaseAllocator`, `ByteAllocator`, `PageAllocator`, and `IdAllocator` are now re-exported from `axallocator` instead of being defined locally
+- Updated Rust toolchain to `nightly-2026-02-25`
+- Benchmarks no longer require `--features bench`; `criterion` and `rand` moved to `[dev-dependencies]`
+
+### Removed
+- Removed locally defined allocator trait and error type definitions (now provided by `axallocator`)
+- Removed the deprecated `bench` feature flag
+
