I am excited about 0.9.7 for a couple of reasons. At the top of that list is the added flexibility. I have cleaned up the settings for the various configuration files and cache folders so that it is possible to reorganize the source tree more to your liking. The creation of all cached files now honors the umask setting from index.php (on *nix platforms). I have also provided a setting in web.xml to use mod_rewrite to push all requests through index.php. By using mod_rewrite, you no longer have to have index.php anywhere in the request URI! Look ma! No index.php!
There are two features that need to be added before 1.0, security and filters. One may even be the result of the other, so keep your eyes peeled!
