 The Windows Server 2003 SP1 Platform SDK build, with its early x64 compiler and
 tools, was accidentally broken in Perl 5.27.9.  This has now been fixed.

+Perl's build and testing process on Mac OS X for C<-Duseshrplib>
+builds is now compatible with Mac OS X System Integrity Protection
+(SIP).
+
+SIP prevents binaries in F</bin> (and a few other places) being passed
+the C<DYLD_LIBRARY_PATH> environment variable.  For our purposes this
+prevents C<DYLD_LIBRARY_PATH> from being passed to the shell, which
+prevents that variable being passed to the testing or build process,
+so running C<perl> couldn't find F<libperl.dylib>.
+
+To workaround that, the initial build of the F<perl> executable
+expects to find F<libperl.dylib> in the build directory, and the
+library path is then adjusted during installation to point to the
+installed library.
