This is mentioned in the users guide associated with the 9.2.1-alpha1
release [1]. We will support both LLVM 10 and 11 in this release.

There will be a Cabal 3.6 release associated with this release however
this branch hasn't happened yet. Hopefully this will be sorted by the
next alpha.

Great news! I couldn't find a mention of the supported llvm version in the
release notes here
.

Also will the llvm compiler option be supported for 9.2.1?

Thanks
George

Hi,

Typically a GHC release is tied to a new cabal release as well. I however
can't find a new tag for Cabal.

Does this mean I need to use cabal-head or can I use Cabal 3.4?

Thanks,
Tamar
