ANN: Release candidate for stack-1.6.1

[Emanuel Borsboom]

I've cut the first stack-1.6.1 release candidate: https://github.com/commercialhaskell/stack/releases/tag/v1.6.0.20171202.  Please give it a try!  I included 64-bit binaries for Linux, macOS, and Windows.  We'll plan on doing the full v1.6.1 release in around a week unless there are any show-stopping bugs.

If you do run into any trouble, please open an issue: https://github.com/commercialhaskell/stack/issues.

Easy way to upgrade:

> stack upgrade --binary-version 1.6.0.20171202

I now run into problems without it!

Looks like you're running into https://github.com/commercialhaskell/stack/issues/3624. Since newer versions of GHC are pulling in cabal files in the 2.0 format, versions of Stack without the Cabal-2.0 library (meaning: everything before 1.6) aren't supported. I've requested that such cabal files be held off in active use until tooling has a chance to upgrade, but that request was denied.

On the bright side: Stack 1.6 is _also_ less eager about parsing cabal files it doesn't need, so this problem will be less of a pain in the future. See: https://github.com/commercialhaskell/stack/issues/3396.

Yes! I ran into the problem before the issue turned up (I'm on 8.2.2). The versioning and compatibility management around these cabal updates continues to be... interesting.

Given these issues, all released versions of Stack are unable to use
Stackage nightly. Can I suggest a swift Stack release? It's certainly
going to be a better experience than doesn't work at all, even if it
has RC1 style bugs left in it. FWIW, all my nightly builds just broke.

Thanks, Neil

We are definitely leaning the same way! In fact I'm building the binaries right now.
