This release has been about improving 404 support. The changes brought both cache header management a overall performance improvements to 404’s.
The Fast 404’s are for static files that are not found on disk. Rather than loading all of WordPress, it stops after loading the (mu-)plugins when it comes accross a known static file type and gives the 404 at that point.
The cache headers for 404’s are now enabled for an intelligent set of cache headers for each file type, or the choice to disable caching of 404’s altogether.
The purge all trigger on save of Permalinks has been added so that if there is change to the permalink structure or that its been re-saved to force rebuilding of the permalinks, the CDN will also reflect these new changes.
