+### Added
+
+- Add AD (ChainRules/Mooncake/Enzyme) pullback rules for (anti-)hermitian projection ([#174](https://github.com/QuantumKitHub/MatrixAlgebraKit.jl/pull/174)).
+- Add `TruncationUnion` to support combining multiple truncation schemes by supplying minimal ranks ([#183](https://github.com/QuantumKitHub/MatrixAlgebraKit.jl/pull/183)).
+- Add `SafeDivideAndConquer` algorithm variant for more robust singular value decompositions ([#185](https://github.com/QuantumKitHub/MatrixAlgebraKit.jl/pull/185)).
+- Add `DefaultAlgorithm` type for explicit dispatch to the default algorithm ([#195](https://github.com/QuantumKitHub/MatrixAlgebraKit.jl/pull/195)).

+- Default algorithms now defined for `SubArray` and `ReshapedArray` ([#182](https://github.com/QuantumKitHub/MatrixAlgebraKit.jl/pull/182)).
+- Separated `Algorithm` and `Driver` concepts for QR/LQ, SVD, and Schur/Eig decompositions ([#178](https://github.com/QuantumKitHub/MatrixAlgebraKit.jl/pull/178), [#189](https://github.com/QuantumKitHub/MatrixAlgebraKit.jl/pull/189), [#194](https://github.com/QuantumKitHub/MatrixAlgebraKit.jl/pull/194), [#196](https://github.com/QuantumKitHub/MatrixAlgebraKit.jl/pull/196)).

+### Fixed

 - QR and LQ decompositions were supposed to default to `positive = true` ([#170](https://github.com/QuantumKitHub/MatrixAlgebraKit.jl/pull/170)).
