mod_authnz_external v3.3.3 (July 22, 2019)

• 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.
• First release with Linux, Mac OS X, and Windows Travis-CI builds.
