Drupal is a popular free and open source publishing platform powering sites such as The White House. This post highlights some of the improvements developed for upcoming Drupal 7 release:

Also enabled caching HTTP headers to be set so that logged out users can cache entire pages locally as well as improve compatibility with reverse proxies and CDNs. A patch would which reduces both response size and time taken to generate 404 responses.
- Drupal supported gzip of HTML, however CSS and JS files are delivered directly by webserver, so Drupal has less control. A patch stores compressed versions of aggregated files on write and uses rewrite and header directives in .htaccess that allow these files to be served correctly.
