+1.21 -- Mon May 18 10:32:14 CDT 2009
+
+ * Change build system for perl-only install not to need to modify blib
+ * When building inside perl, tests for weaken should be always run (Alexandr Ciornii)
+
+1.20 -- Wed May 13 16:42:53 CDT 2009
+
+*** NOTE***
+This distribution now requires perl 5.6 or greater
+
+Bug Fixes
+ * Fixed stack pop issue in POP_MULTICALL
+ * Fixed error reporting in import when XS not compiled
+ * Check first argument to reduce is a CODE reference to avoid segfault
+ * Handle overloaded and tied values
+ * Fix tainted test to run on Win32
+
+Enhancements
+ * Added List::Util::XS so authors can depend on XS version
+ * Removed need for dummy methods in UNIVERSAL for perl-only code
+
+

+=item Weak references are not implemented in the version of perl

+C<isweak> or C<weaken> you will need to use a newer release of perl.

+C<Scalar::Util> contains both perl and C implementations of many of its functions
+so that those without access to a C compiler may still use it. However some of the functions
+are only available when a C compiler was available to compile the XS version of the extension.
