+----------------------------------------------
+ * Added METHOD environment variable to retrieve the HTTP request method 
+   (e.g. GET, HEAD, POST, OPTIONS, etc.). Thanks to Vijay from Google Code.
+ * Fixed a bug with incorrect parenthesis grouping when checking the result
+   of the external process in exec_external(). Thanks to @dcb314.
+ * Added the "GroupExternalAuthNCheck Off" directive to disable the check
+   for a previously authenticated user when using *only* the group 
+   authorization module. If you use *any* user authentication module in the
+   same context, this may be undesirable. Thanks to Micah Andersen/BIMI.
+ * Fix launching external processes on Windows - many programs require the
+   %SystemRoot% environment variable to function properly. Thanks to Micah
+   Andersen/BIMI.
