Are you using DS Plug-in system and wondering if your code would still work in the new version? Then answer is Yes. DSPS has been adjusted where necessary to support a new version of Delphi.
At this time I am actively testing all my components to ensure that everything is done properly.
Delphi 2009 is not yet out so I cannot publish a new version yet but if you are a Tiburon beta tester you want to try a latest release by sending me an email.
