As some of these issues are soundness issues users are strongly +encouraged to upgrade. + + +Highlights +---------- + +The highlights, since the 8.6.2 release, are: + +- A bug resulting in segmentation faults in some programs has been fixed + (:ghc-ticket:`15892`) +- Darwin binary distributions are now correctly built against an in-tree + ``libgmp`` (:ghc-ticket:`15404`) +- Three bugs leading to linker failures on Windows has been fixed + (:ghc-ticket:`15105`, :ghc-ticket:`15894`, :ghc-ticket:`15934`) +- A bug leading to programs with deep stacks crashing when run with retainer profiling enabled has been fixed (:ghc-ticket:`14758`) +- A bug resulting in potential heap corruption during stable name allocation has been fixed (:ghc-ticket:`15906`) +- Plugins are now loaded during GHCi sessions (:ghc-ticket:`15633`) + +Known issues +------------ + +Note that the LLVM code generator (:ghc-flag:`-fllvm`) in GHC 8.6, as well as +all earlier releases, are affected by :ghc-ticket:`14251`, which can result in +miscompilation of some programs calling functions with unboxed floating-point +arguments. While originally scheduled to be fixed for this release, the fix +ended up being more difficult than anticipated and, given that issue is not a +strict regression from 8.4, we decided to proceed with the release. + +Included libraries +------------------ + +The package database provided with this distribution also contains a number of +packages other than GHC itself.
