+=head2 Thread Safety
+
+Getopt::Long is thread safe when using ithreads as of Perl 5.8. It is
+I<not> thread safe when using the older (experimental and now
+obsolete) threads implementation that was added to Perl 5.005.
=head2 Documentation and help texts
+Changes in version 2.32
+-----------------------
+
+* Fix a bug where the initial value for a optional numeric argument
+was not used for value of a hash option.
+
+* Remove 5.005 thread safety code. Getopt::Long is completely thread
+safe when using the 5.8 ithreads.
