+
+The GHC team is proud to announce the first release candidate of 8.6.5.
+The source distribution, binary distributions, and documentation are
+available on
+[downloads.haskell.org](https://downloads.haskell.org/~ghc/8.6.5-rc1).
+
+This release fixes a handful of issues with 8.6.4:
+
+ - Binary distributions once again ship with Haddock documentation including
+   syntax highlighted source of core libraries (#16445)
+
+ - A build system issue where use of GCC with `-flto` broke `configure`
+   was fixed (#16440)
+ 
+ - An bug affecting Windows platforms wherein XMM register values could be
+   mangled when entering STG has been fixed (#16514)
+ 
+ - Several Windows packaging issues resulting from the recent CI rework.
+   (#16408, #16398, #16516)
+
+Since this is a relatively small bugfix release we are bypassing the
+alpha releases and moving right to the release candidate stage. If all
+goes well the final release will be cut next week.
+
+As always, if anything looks amiss do let us know.
+
+Happy testing!
