Loosing his old URLs is not always a good thing and not only for the ranking in google. I got a couple of requests to restore them, here you go, old post URLs are back.

Here is the lighttpd rewrite rules for the old rss.php file and the post access, if anyone needs it (not really rocket sciences, but copy/paste can be faster :

         url.rewrite-once = (                 "^/rss\.php" => "/index.php/feed/rss2",                 "^/index\.php/([0-9]{4}.*)" => "/index.php/post/$1"         ) 

Update You can find further rules for apache’s mod_rewrite in the dotclear’s forum. If you need some of them for lighttpd, let me know, I can try to "port" them (I’m happy with the two rules above).
