The destructor is named __destruct() in PHP5.

The name of the constructor has changed to __construct. But as a 
fallback a method with the same name as the class is used (that's the 
old behaviour).

Found some nice articles on 
http://www.phpvolcano.com/articles/php5/index.php.

The article states that objects will always be passed by reference. No 
backwards compatibility is mentioned. So I guess now Typo3 will have to 
be re-tested and scanned for occurences where an explicit copy is required.

Other changes are extensions of the syntax, which are of course 
incompatible.

But of course the spec is this: http://www.php.net/zend-engine-2.php

Don't know if it concernes Typo3, but PHP5 now used libxml2 for XML-support.
