Hello everyone,

The week before ICFP I was able to get the ghc-8.0 branch ready for an
8.0.2 release, which I intended to cut this week. In the intervening
time an additional rather serious issue was reported affected Mac OS X
Sierra (#12479). Since this issue affects the usability of GHC on the
new OS X release, we'll be deferring the 8.0.2 release until it has been

While there appears to be an actionable path forward on this ticket, we
will need someone with an affected machine and an understanding of GHC's
use of dynamic linking to step up to implement. Otherwise it looks like
the release will be delayed at least until October 9, when darchon has
time to have a look.

Sorry to be the bearer of bad news!
