The HLS team is pleased to announce the release of Haskell Language Server [2.7.0.0](https://github.com/haskell/haskell-language-server/releases/tag/2.7.0.0).

Binaries for this release are available at  
[Index of /~hls/haskell-language-server-2.7.0.0/](https://downloads.haskell.org/~hls/haskell-language-server-2.7.0.0/).

These binaries can be installed using [GHCup](https://www.haskell.org/ghcup/), using the vanilla metadata channel.

```bash
ghcup --url-source=https://raw.githubusercontent.com/haskell/ghcup-metadata/master/ghcup-vanilla-0.0.8.yaml install hls 2.7.0.0

```

All of these tarballs have associated GPG signatures. The signature should be from `Hannes Siebenhandl <hannes.siebenhandl@posteo.net>` (key ID [9849506453CA97E75F505D054EF829564CA34FC8](https://keys.openpgp.org/search?q=9849506453CA97E75F505D054EF829564CA34FC8)).

The prebuilt binaries in this release support the following GHC versions:

- 9.2.8
- 9.4.8
- 9.6.4
- 9.8.2

## ChangeLog

- Bindists for GHC 9.8.2
  - Enable many more plugins, making GHC 9.8.2 fully supported

- Fix refactor code actions for vim
- Preserve HLint’s diagnostic severity
- Many other bug fixes.

Just to be clear: GHCup developers **advise against using the vanilla channel**. This is for expert users, who know what they are doing. These binaries are not rigorously reviewed and maintained by GHCup developers. They’re added as-is from upstream.

The above binaries may also not be ABI compatible with the GHC binaries from the default non-vanilla channel. VSCode haskell extension also relies on the default non-vanilla channel. It’s possible to drive your ghcup toolchain unusable mixing different channels.

Instead it is advised to wait for the proper ghcup bindists.
