1.8.0.0

Binaries for this release are available at https://downloads.haskell.org/~hls/haskell-language-server-1.8.0.0/.

All of these tarballs have associated GPG signatures. The signature should be from Zubin Duggal <zubin@well-typed.com> (key ID 588764FBE22D19C4).

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

• 8.6.5
• 8.8.4
• 8.10.7
• 9.0.2
• 9.2.3
• 9.2.4
• 9.4.1
• 9.4.2

These binaries can be installed using GHCup or version 2.0.0 and above of the VSCode extension. Older versions of the VSCode extension will not attempt to download this version.

Installation

For non-Windows platforms, there is now a Makefile which will install a dynamically linked version of HLS after verifying that it is compatible with your local GHC installation.

You must download the tarball with the most similar platform suffix to the GHC bindist you installed from https://downloads.haskell.org/~ghc/ - for instance, if you used ghc-8.10.7-x86_64-fedora27-linux.tar.lz to install GHC, you will need haskell-language-server-1.8.0.0-x86_64-linux-fedora33.tar.xz.

If you use GHCup to install, then it will automatically make this decision for you.

If you get your GHC binaries from a source other than https://downloads.haskell.org (or GHCup), then you will need to build HLS from source yourself.
