+Release notes for version 8.6.3
+===============================
+
+GHC 8.6.3 is a bug-fix release, fixing a few regressions found in 8.6.1 and
+8.6.2. 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.
+
