# Changelog All notable changes to metatensor-operations are documented here, following the [keep a changelog](https://keepachangelog.com/en/1.1.0/) format. This project follows [Semantic Versioning](https://semver.org/spec/v2.0.0.html). ## [Unreleased](https://github.com/metatensor/metatensor/) ## [Version 0.2.4](https://github.com/metatensor/metatensor/releases/tag/metatensor-operations-v0.2.4) - 2024-10-11 ### Changed - `block_from_array` now takes optional parameters to specify the names of sample, component and property dimensions ## [Version 0.2.3](https://github.com/metatensor/metatensor/releases/tag/metatensor-operations-v0.2.3) - 2024-08-28 ### Changed - We now require Python >= 3.9 - `slice` and `drop_blocks` are now faster thanks to `Labels.select` ## [Version 0.2.2](https://github.com/metatensor/metatensor/releases/tag/metatensor-operations-v0.2.2) - 2024-06-19 ### Fixed - Fixed a bug in `metatensor.torch.sort` where the labels where not properly sorted (#647) - Fix `metatensor.abs` when used with complex values (#553) ## [Version 0.2.1](https://github.com/metatensor/metatensor/releases/tag/metatensor-operations-v0.2.1) - 2024-03-01 ### Changed - Use `torch.jit.script` by default on all operations when using the TorchScript backend (i.e. `metatensor.torch`) (#504) ## [Version 0.2.0](https://github.com/metatensor/metatensor/releases/tag/metatensor-operations-v0.2.0) - 2024-02-07 ### Changed - `join()` operation now includes the `sort_samples` argument to control the sorting of samples in the output joined TensorMap. This defaults to False, opposite to the previous default behaviour. ### Added - `detach()` operation to detach all values in a TensorMap/TensorBlock from any computational graph - `requires_grad()` operation to set the `requires_grad` of all values in a TensorMap/TensorBlock when storing data in torch Tensors. ### Removed - the `to` operation was removed. Similar functionality is now offered by `TensorMap.to`, `TensorBlock.to`, and the operations `detach()` and `requires_grad()`. ## [Version 0.1.0](https://github.com/metatensor/metatensor/releases/tag/metatensor-operations-v0.1.0) - 2023-10-11 ### Added - Creation operations: `empty_like()`, `ones_like()`, `zeros_like()`, `random_like()`, `block_from_array()`; - Linear algebra: `dot()`, `lstsq()`, `solve()`; - Logic function: `allclose()`, `equal()`, `equal_metadata()`; - Manipulation operations: `drop_blocks()`, `join()`, `manipulate dimension`, `one_hot()`, `remove_gradients()`, `samples reduction`, `slice()`, `split()`, `to()`; - Mathematical functions: `abs()`, `add()`, `divide()`, `multiply()`, `pow()`, `subtract()`; - Set operations: `unique_metadata()`, `sort()`;
