### Performance

## [0.17.1](https://github.com/QuantumKitHub/TensorKit.jl/compare/v0.17.0...v0.17.1) - 2026-07-13

### Added

- Enzyme AD support: forward and reverse rules (with tests) for TensorOperations contractions, linear algebra, and VectorInterface operations, and reverse rules for index manipulations ([#436](https://github.com/QuantumKitHub/TensorKit.jl/pull/436), [#437](https://github.com/QuantumKitHub/TensorKit.jl/pull/437), [#440](https://github.com/QuantumKitHub/TensorKit.jl/pull/440), [#449](https://github.com/QuantumKitHub/TensorKit.jl/pull/449), [#451](https://github.com/QuantumKitHub/TensorKit.jl/pull/451), [#466](https://github.com/QuantumKitHub/TensorKit.jl/pull/466))
- `exponential` and `exponential!` for the matrix exponential of tensors ([#465](https://github.com/QuantumKitHub/TensorKit.jl/pull/465))
- Docstrings for `catdomain` and `catcodomain` ([#485](https://github.com/QuantumKitHub/TensorKit.jl/pull/485))

### Changed

- Consolidated duplicated GPU logic into a new GPUArrays extension ([#460](https://github.com/QuantumKitHub/TensorKit.jl/pull/460))
- Removed explicit dependence on cuTENSOR for the CUDA extension; importing `cuTENSOR` is still recommended for best performance, as it enables the corresponding TensorOperations extension ([#455](https://github.com/QuantumKitHub/TensorKit.jl/pull/455))
- Improved `DimensionMismatch` error message in the `TensorMap` constructor ([#456](https://github.com/QuantumKitHub/TensorKit.jl/pull/456))

### Fixed

- Added missing zero-derivatives and an in-place rrule test for `svd_trunc` ([#448](https://github.com/QuantumKitHub/TensorKit.jl/pull/448))

### Performance

- Reduced overhead in the `TensorMap` constructor and in `sectorequal`/`sectorhash` for trivial symmetries ([#476](https://github.com/QuantumKitHub/TensorKit.jl/pull/476))
- Further trivial-symmetry improvements and reduced respecialization for `contract!` ([#479](https://github.com/QuantumKitHub/TensorKit.jl/pull/479))
- Fast path for trivial tensors into the TensorOperations machinery ([#463](https://github.com/QuantumKitHub/TensorKit.jl/pull/463))
- Marked more error strings as lazy to reduce runtime overhead ([#478](https://github.com/QuantumKitHub/TensorKit.jl/pull/478))
