Thanks Ben! When testing, I found that a type checker regression from 7.10
to 8.0 that I thought/hoped was resolved is in fact still present in this
release candidate. I filed a new bug:
https://ghc.haskell.org/trac/ghc/ticket/12885
It originally seemed the same as #12175. But unfortunately, although that
problem is resolved in 8.0.2-rc1, this one is still around (though they may
still be related).
Thanks,

Hello everyone,
The GHC team is happy to (finally!) announce the first candiate of the 8.0.2 release of the Glasgow Haskell Compiler. Source and binary distributions are available at
http://downloads.haskell.org/~ghc/8.0.2-rc1/
This is the first of what will hopefully be only two release candidates leading up the final 8.0.2 release. This release will fix a number bugs found in 8.0.1 including,
* Interface file build determinism (#4012).
* Compatibility with macOS Sierra and GCC compilers which compile position-independent executables by default
* Runtime linker fixes on Windows (see #12797)
* A compiler bug which resulted in undefined reference errors while compiling some packages (see #12076)
* Compatability with systems which use the gold linker
* A number of memory consistency bugs in the runtime system
* A number of efficiency issues in the threaded runtime which manifest on larger core counts and large numbers of bound threads.
* A typechecker bug which caused some programs using -XDefaultSignatures to be incorrectly accepted.
* More than two-hundred other bugs. See Trac [1] for a complete listing.
Unfortunately there is one known bug (#12757) which can result in runtime crashes which is still lurking in -rc1. This will be fixed in -rc2, which will be released in about a week.
As always, let us know if you encounter trouble. Thanks to everyone who has contributed so far!
Happy testing,
- Ben
