+- Add equality comparison (`==`) for `TruncationStrategy` types ([#211](https://github.com/QuantumKitHub/MatrixAlgebraKit.jl/pull/211)).
+
+### Changed
+
+- Reorganized pullback implementations and fixed pullback correctness for rank-degenerate SVD cases ([#208](https://github.com/QuantumKitHub/MatrixAlgebraKit.jl/pull/208)).
+- Centralized QR/LQ gauge-fixing logic ([#203](https://github.com/QuantumKitHub/MatrixAlgebraKit.jl/pull/203)).
+- Bumped CUDA compat to v6, dropping support for older versions ([#209](https://github.com/QuantumKitHub/MatrixAlgebraKit.jl/pull/209)).
+- Replaced `CompatHelper` with `dependabot` for dependency updates ([#212](https://github.com/QuantumKitHub/MatrixAlgebraKit.jl/pull/212)).
