13 January 2014 CORS Filter 1.9.2 adds improved support for caching and CDN management. Thanks to Chris Knowles for raising the issue and helping out with its resolution. We're also looking for a volunteer to implement a new configuration mechanism, see issue #15.

29 December 2013 CORS Filter 1.9 can now load the configuration properties file from a location relative to the application's classpath. Thanks to Sharmarke Aden for contributing this snippet.

5 November 2013 CORS Filter 1.8 switches to a servlet context method to load the CORS configuration properties file in a more consistent and reliable way. Comments and feedback are welcome as always.

18 June 2013 CORS Filter 1.7.1 fixes a bug in the request handler, thanks to Ed Scadding for spotting it and contributing the fix!
