Just be-careful using the older PHP builds as some do contain some wild security issues.
The current status is that the smarty people actually dont feel its enough to warrant a new release just yet. I have been speaking to them in smarty channels for some days now. Im a heavy smarty user and its causing problems. However if your brave you can use the CVS smarty version. I believe the last ADODB release has fixed the issues relating to that layer.
Hope that helps a little too.
