tl;dr: We are giving this release another attempt. Cross your fingers and try building again. Hello GHC packagers, Thanks for your help in the last few days working through what were hopefully the last issues in the release. I've uploaded a new set of source tarballs at, http://downloads.haskell.org/~ghc/8.0.1/ These tarballs are derived from, 787900138b94790ddd13d76c2853d789d3335a5d This commit differs from the previous tarball in a number of ways, * a variety of packaging issues surrounding haddock's documentation have been fixed * the ghc-boot library has been split up. It was pointed out quite late that the previous structure of ghc-boot greatly increased the dependency footprint of the template-haskell package, which would have made it nearly impossible to upgrade the bytestring and binary packages. * a pair of fixes for crashes on PowerPC have been merged * a patch addressing a serious performance issue in parallel garbage collection has been merged * the bytestring module has been bumped to 0.8.10.1, fixing a rather serious correctness issue on big-endian systems We'll have the usual one-week build window for binary distributions. As always, let either Austin or I know if you have any trouble building your distribution. I have yet to push the ghc-8.0.1 tag in case we encounter unexpected issues but all of my builds with this tarball thusfar have gone quite well (then again, so did those of the previous tarball). Good luck and thanks for all of your work! Cheers, - Ben
