There are no real changes in here from alpha1 beyond a few documentation changes. Everything is functionally the same.
With no new bug reports since January, I'm releasing as beta stability to increase exposure.
Initial release of module that contains s-maxage support and custom global caching for 404, 302 and 5xx level.
Note that with 5xx, cache headers can only be set if Drupal is rendering the 5xx response. If a php fatal error occurs, cache headers will not be controlled by this module.
