As always, a big thank you to the all of the contributors! This release saw changes from 125 contributors.
Breaking changes:
- `suffix` file-types in the `file-types` key in language configuration have been removed ([#8006](https://github.com/helix-editor/helix/pull/8006))
- The `file-types` key in language configuration no longer matches full filenames without a glob pattern ([#8006](https://github.com/helix-editor/helix/pull/8006))
