+A new makefile option, USE_64_BIT_INT, has been added to the Windows makefiles.
+Set this to "define" when building a 32-bit perl if you want it to use 64-bit
+integers.
+
+Machine code size reductions, already made to the DLLs of XS modules in 5.17.2,
+have now been extended to the perl DLL itself.
+
+Building with VC++ 6.0 was inadvertently broken in 5.17.2 but has now been
+fixed again. XXX Actually, it's now been broken again, so ensure that it gets
+fixed once more before release, or remove this comment!

Under debugging builds, the B<-DA> command line option started crashing in
Perl 5.16. It has been fixed [perl #114368].

+
+A potential deadlock scenario involving the premature termination of a
+pseudo-forked child in a Windows build with ithreads enabled has been fixed.
+This resolves the common problem of the F<t/op/fork.t> test hanging on Windows.
