    [FEATURES]
    - This now works:
            $webapp->query($new_query_object);
      Setting a new query object can be useful in combination with
      CGI::Application::Server.  (Jaldhar Vyas)

    [DOCUMENTATION]
    - typo fix (Lyle)

4.19_1 Fri Sep 27, 2008

    [FEATURES]
    - New 'html_tmpl_class' method allows you to specify an alternative
      HTML::Template class. This technique will eliminate the need to use
      a plugin for HTML::Template-compatible classes. See the docs
      for load_tmpl() for details.

      Thanks to Rhesa Rozendaal for the initial patch, and Mark Stosberg for
      documentation refinements.

    [DOCUMENTATION]
    - typo fix (George Hartzell)
    - Revert back to documenting the use of "$self", not $c, after \ 
community
      feedback.

    [INTERNALS]
    - Change how default run modes are declared for better compatibility
      with AutoRunmode and RunmodeDeclare plugins. Thanks Rhesa via RT#39631.
