### Fixed

### Performance

## [0.6.8](https://github.com/QuantumKitHub/MatrixAlgebraKit.jl/compare/v0.6.7...v0.6.8) - 2026-05-20

### Added

- Add a MatrixAlgebraKit logo ([#230](https://github.com/QuantumKitHub/MatrixAlgebraKit.jl/pull/230)).

### Changed

- Extended AD test coverage to CUDA arrays for the polar decomposition ([#237](https://github.com/QuantumKitHub/MatrixAlgebraKit.jl/pull/237)) and the Mooncake projection rules ([#240](https://github.com/QuantumKitHub/MatrixAlgebraKit.jl/pull/240)).

### Fixed

- Pullbacks of `eig_trunc`, `eigh_trunc`, and `svd_trunc` no longer error when the truncation strategy keeps no values; `svd_pullback!` also handles the zero-rank case where every singular value falls below `rank_atol` ([#233](https://github.com/QuantumKitHub/MatrixAlgebraKit.jl/pull/233)).
- `svd_pullback!` is now GPU-compatible ([#232](https://github.com/QuantumKitHub/MatrixAlgebraKit.jl/pull/232)).
- LQ pullback no longer modifies input cotangents ([#226](https://github.com/QuantumKitHub/MatrixAlgebraKit.jl/pull/226)).
- `eigh` pullback now works on CUDA arrays ([#235](https://github.com/QuantumKitHub/MatrixAlgebraKit.jl/pull/235)).
- `eig` pullback now works on CUDA arrays ([#236](https://github.com/QuantumKitHub/MatrixAlgebraKit.jl/pull/236)).
- Corrected the Enzyme rule's check for when the cached output argument must be copied ([#239](https://github.com/QuantumKitHub/MatrixAlgebraKit.jl/pull/239)).

### Performance

- Improved `svd` gauge-fixing performance ([#238](https://github.com/QuantumKitHub/MatrixAlgebraKit.jl/pull/238)).
