Hi

I believe llvm 15 does not work in this alpha as 21936 is still open. Is that correct?

I also believe that when it does work ghc 9.6 will not be compatible with earlier versions of llvm. Is that correct?

Thanks George

The GHC team is very pleased to announce the availability of GHC 9.6.1-alpha1. As usual, binaries and source distributions are available at downloads.haskell.org:

https://downloads.haskell.org/ghc/9.6.1-alpha1/

This is the first alpha release in the 9.6 series which will bring a number of exciting features:

* A new Javascript code generation backend

* A new WebAssembly code generation backend,

* Significant latency improvements in the non-moving garbage collector

* Support for loading of multiple components in GHCi

* Efficient support for delimited continuations

* Improvements in error messages

* Numerous improvements in compiler-residency

Note that both the Javascript and WebAssembly backends are still in a state of infancy and are present in this release as a technology preview; we hope that they will mature considerably before the final 9.6.1 release.

Please give this release a try and open a [ticket] if you see anything amiss.

Cheers,

- Ben
