A new alpha version of Flightpath is now available, version 0.421-RC1. This update includes a fix for the perma-link structure and and an improved “last 10” listing on the home page. (However, in order to implement this feature I used a PHP 5 only feature–so it will not work on PHP 4. In future releases I may try to reinstate backward compatibility with PHP 4.)
You can find out more information about this release on the codex page about it.
