7. Release notes for version 8.6.5¶
GHC 8.6.5 is a bug-fix release, fixing a few regressions found in 8.6.4.
7.1. Highlights¶
The highlights, since the 8.6.4 release, are:
Binary distributions once again ship with Haddock documentation including syntax highlighted source of core libraries (Trac #16445)
A build system issue where use of GCC with
-flto
brokeconfigure
was fixed (Trac #16440)An bug affecting Windows platforms wherein XMM register values could be mangled when entering STG has been fixed (Trac #16514)
Several packaging issues with the Windows binary distributions have been resolved. (Trac #16408, Trac #16398, Trac #16516).
7.2. Known issues¶
Note that the LLVM code generator (-fllvm
) in GHC 8.6, as well as
all earlier releases, are affected by Trac #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.
7.3. Included libraries¶
The package database provided with this distribution also contains a number of packages other than GHC itself. See the changelogs provided with these packages for further change information.
