# Changelog
This documents the main changes to the `tch` crate.

The format is based on [Keep a Changelog](https://keepachangelog.com/en/1.0.0/)
and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).

## v0.12.0 - unreleased
### Changed
- EfficientNet models have been reworked, pre-trained models used `safetensors`
  weight by default, [679](https://github.com/LaurentMazare/tch-rs/pull/679).
- None can be used for nullable scalar types,
  [680](https://github.com/LaurentMazare/tch-rs/pull/680).
- Automated conversion of list arguments: all the generated functions that take
  as input a slice of int or float can now be used directly with int values or
  fixed length arrays [682](https://github.com/LaurentMazare/tch-rs/pull/682).
- Replace the `From<Tensor>` traits with some `TryFrom` versions,
  [683](https://github.com/LaurentMazare/tch-rs/pull/683). This is a breaking
  change, note that also the old version would flatten the tensor if needed to
  reduce the number of dimensions, this has to be done explicitely with the new
  version.

## v0.11.0 - 2023-03-20
### Added
- Adapt to C++ PyTorch library (`libtorch`) version `v2.0.0`.
### Changed
- Update the `half` dependency to version `2`, [646](https://github.com/LaurentMazare/tch-rs/pull/646).

## v0.10.3 - 2023-02-23
### Added
- Add some helper functions in a utils module to check the available devices and versions.

## v0.10.2 - 2023-02-19
### Added
- Add the `eps` and `amsgrad` options to Adam, [600](https://github.com/LaurentMazare/tch-rs/pull/600).
### Changed
- Fix loading of `VarStore` when using `Mps` devices, [623](https://github.com/LaurentMazare/tch-rs/pull/623).
- Use `ureq` instead of `curl` to reduce compile times, [620](https://github.com/LaurentMazare/tch-rs/pull/620).
- Fix the handling of dicts in TorchScript, [597](https://github.com/LaurentMazare/tch-rs/issues/597).

## v0.10.1 - 2022-12-12
### Changed
