(fwd to the real haskell cafe list) -- Dan Burton ---------- Forwarded message --------- From: Dan Burton <danburton.email@gmail.com> Date: Sat, Nov 10, 2018 at 11:30 AM Subject: Re: [Haskell] [ANNOUNCE] GHC 8.6.2 is now available To: Ben Gamari <ben@well-typed.com> Cc: Haskell-cafe <haskell-cafe@googlegroups.com> I have two trivialities to bring up: 1. Could you update https://downloads.haskell.org/~ghc/latest/ to point to 8.6.2? (It's currently showing 8.6.1.) 2. The SHA1SUMS and SHA256SUMS for 8.6.2 list a file "./ghc-8.6.2-x86_64-darwin.tar.xz", but that is a broken link; the corresponding file is found at "./ghc-8.6.2-x86_64*-apple*-darwin.tar.xz". Can these be harmonized? Thanks! -- Dan Burton On Mon, Nov 5, 2018 at 11:29 AM Ben Gamari <ben@well-typed.com> wrote:

Hello everyone,

The GHC team is very happy to announce the availability of GHC 8.6.2, a bugfix release to GHC 8.6.1. The source distribution, binary distributions, and documentation for this release are available at

https://downloads.haskell.org/~ghc/8.6.2

The 8.6 release fixes several regressions present in 8.6.1 including:

* A long-standing (but previously hard to manifest) bug resulting in undefined behavior for some applications of dataToTag# has been fixed (#15696)

* An incorrect linker path to libgmp in the Mac OS binary distributions (#15404)

* A regression rendering Windows installations to read-only directories unusable (#15667)

* A regression resulting in panics while compiling some record updates of GADTs constructors (#15499)

* A regression resulting in incorrect type errors when splicing types into constraint contexts has been fixed (#15815)

* Around a dozen other issues.

See Trac [1] for a full list of issues resolved in this release.

Note that this release ships with one significant but long-standing bug (#14251): Calls to functions taking both Float# and Double# may result in incorrect code generation when compiled using the LLVM code generator. This is not a new issue, it has existed as long as the LLVM code generator has existed; however, changes in code generation in 8.6 made it more likely that user code using only lifted types will trigger it.

Happy compiling!

Cheers,

- Ben
