Hi Austin,
We've closed approximately 45 tickets that people filed for RC1 in this release. Thank you for all the reports!
Good work!
We plan to make the final 7.8.1 release soon, and hope RC2 will be the last RC. So *please* test as much as possible; bugs are much cheaper if we find them before the release!
Unfortunately, ghc-7.8.0.20140228-src does not have: https://github.com/haskell/cabal/commit/ee6d1cf5cefe18f6d74ed379af21d92f8b0a... So, ghc-7.8.0.20140228-x86_64-apple-darwin-mavericks does not use @rpath: % otool -L libHSmtl-2.1.2-ghc7.8.0.20140228.dylib libHSmtl-2.1.2-ghc7.8.0.20140228.dylib: /Users/kazu/work/cab/.cabal-sandbox/lib/x86_64-osx-ghc-7.8.0.20140228/mtl-2.1.2/libHSmtl-2.1.2-ghc7.8.0.20140228.dylib (compatibility version 0.0.0, current version 0.0.0) --Kazu
