Gergely Hodicska has posted part four of his "what's new in PHP 5.3" series - a sort of "wrapup" for some of the smaller features that have been added. Among them are:

• __callStatic
• OpenID support
• user.ini user defined ini functionality
• dynamic static calls
• XSLT profiling

...and many more. Check out the post for more to add to the list and for some brief examples of the ones already mentioned.
