## Additions

### Substring match algorithm

In [#15511](https://github.com/nushell/nushell/pull/15511), [@vansh284](https://github.com/vansh284) added the option to use substring matching for completions. Previously, only prefix and fuzzy matching were allowed. Users can now set `$env.config.completions.algorithm` to `"substring"` to enable this.

Custom completers already had the ability to use substring matching by setting `positional: false` in their [options](https://www.nushell.sh/book/custom_completions.html#options-for-custom-completions). However, `positional` has now been deprecated, and completers should set `completion_algorithm: "substring"` to maintain the same behavior.

## Breaking changes

## Deprecations

### `positional` completer option

The `positional` [option](https://www.nushell.sh/book/custom_completions.html#options-for-custom-completions) available to custom completers has been deprecated. See the section about the [Substring match algorithm](#substring-match-algorithm-toc) above for details.
