FWIW the index manipulation rules do not have forward mode (yet)

I mostly just wanted to get this process started, do you think we should try and get that in before actually releasing?

I don't think it's blocking at all but might be good to mention

||
| - 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 ([#455](https://github.com/QuantumKitHub/TensorKit.jl/pull/455)) |

Might also be good to explain here further that for best performance, users should still import cuTENSOR, which will then enable the corresponding TO extension

TensorKit.jl v0.17.1
A feature-and-performance patch release adding a matrix exponential (
exponential/exponential!), broad Enzyme AD support, and several trivial-symmetry performance improvements.Highlights
exponentialandexponential!for tensors (Exponential #465)TensorMapconstructor and trivial-symmetry code paths (Bypass some overhead in TensorMap constructor, bypass overhead insectorequal/sectorhashfor trivial symmetry #476, perf: Trivial symmetry performance improvements #479, Trivial tensors fast path into TensorOperations machinery #463, Mark more error strings lazy #478)Full Changelog
See CHANGELOG for the complete list of changes.
Warning
Do not merge / register yet. This release intentionally includes #465 and #479, which are still open. Once both are merged into
main,mainwill be merged into this branch to pull in their code before tagging.
