+    Bug Fixes
+    * Building *.C files was broken in 6.37. [rt.cpan.org 45557]
+      Thanks to Rajesh Mandalemula for spotting it.
+    New Features
+    * Optional parameter CONFIGURE_REQUIRES was added, to control

+6.51_02  Mon Apr 13 21:19:56 PDT 2009
+    Bug Fixes
+    * Fix a minor bug with the new PERM_DIR stuff which caused EUI to think
+      PERM_DIR was an install skip file.
+    * A Win32 function call in the last alpha broke Win32 builds.
+
+
+6.51_01  Fri Apr 10 14:30:27 PDT 2009
+    New Features
+    * Module installation will not be stopped by a broken Pod::Man.
+      Man pages will just not be installed.
+      [rt.cpan.org 43546] (Jesse Vincent)
+    * vim swap files, *.swp, will now be ignored by MakeMaker.
+    * Added PERM_DIR to control permissions on directories.
+      [rt.cpan.org 3927] (Rajesh Mandalemula)
+
+    Feature Changes
+    * Modules in PREREQ_PM are no longer loaded in order to figure out
+      their version.  parse_version() is used instead.
+      [rt.cpan.org 44646]
+    * PPD files generated with "make ppd" now use the new REQUIRES key
+      rather than the now deprecated DEPENDENCY.
+      [rt.cpan.org 25179] (GAAS)
+    * PPD files no longer contain the deprecated OS tag.
+    * fixin is a bit less restrictive allowing things like 
+      #!perl5.8.8 and #!perl-debug [rt.cpan.org 29442]
+    * Remove the unused perm_rw() and perm_rwx() methods.
+
+    Bug Fixes
+    * On 5.10 "make ppd" would generate the wrong ARCHITECTURE saying the
+      version is 5.1 instead of 5.10.
+    * Our pod2man emulation now requires an argument to --perm_rw.
+      [rt.cpan.org 35190] (imacat)
+    * DISTVNAME was documented as a WriteMakefile() param but you'd
+      get a warning if you tried to use it.  [rt.cpan.org 43217]
+    * Better support for parallel make installs.
+      [rt.cpan.org 32758] (Brendan O'Dea)
+    * parse_version() will now skip uses of $VERSION in conditions
+      [rt.cpan.org 9452] (jc@unser.net)
+    * The architecture mismatch warning could show up on Win32 due
+      to long vs short filenames being used to compare.
+      [rt.cpan.org 33532] (DAGOLDEN)
+    * maybe_command() will recognize Windows executables in
+      /cygdrive on Cygwin [rt.cpan.org 16375] (PJF)
+    * parse_version() will now look for the first use of $VERSION
+      that results in $VERSION being set.
+
+    Test Fixes
+    * basic.t will not leave a "bin" environment variable defined on VMS.
+      [rt.cpan.org 42150] (John E. Malmberg)
+    * Made the tests work ok on systems whose makes assume that files which
+      have the same mod time are out of date.  This is often the case for
+      the tests which generate files and run make rapidly.
+      [rt.cpan.org 29955] (Ken Hirsch)
+    * skip test numbers were wrong on VMS in t/basic.t
+      [rt.cpan.org 43511] (John E. Malmberg)

+
+    VMS
+    * Fixed a few calls to catfile() that should be catdir().
+      (John E. Malmberg)
+    * Override catdir() and catfile() to expand macros.  This is normally done
+      inside File::Spec::VMS but is really a MakeMaker-only thing.
+      (John E. Malmberg)
+
+    Other
+    * Remove ExtUtils::MakeMaker::bytes and vmsish which are unused and
+      seem to never have been used.
+    * Repository now on github.

+
+6.50  Sun Mar 22 12:28:06 PDT 2009
+    Windows    
+    * Remove the special checks for compilers that need a "manifest".  Instead,
+      the code will just be a no-op if there's no manifest.  Or something.
+      I dunno, I'm hoping Jan and Steve know what they're doing.
+      [rt.perl.org 61492]

+6.49_01  Thu Feb 19 17:06:36 PST 2009
+    New OS Support
+    * Recognize "Haiku", a resurrection of BeOS.
+
+    New Features
+    - META.yml now includes ExtUtils::MakeMaker in build_requires by
+      default.
+
+    Test Fixes
+    - ExtUtils::Install 1.51 changed its output breaking some tests that

+    Bug Fixes
+    - Upgrade bundled modules:  ExtUtils::Install 1.52, ExtUtils::Command
+      1.16, ExtUtils::Manifest 1.56.
+
+    Other
