It has a number of optimizations that make it faster and smaller (early estimates say 10-20% faster), a built-in webserver for testing purposes, and features that had been destined for PHP 6.0. The big addition from the now-crashed PHP 6.0 project is Traits, which are sort of a cross between a class and an interface, bringing some of the advantages of multiple inheritance to PHP. The full changelog and download page are both available."

Like every other tool, multiple inheritance can be used or abused. It may be one of those tools which is actually more prone to abuse than to proper use, but that doesn't mean it can't be done right.
For a specific example, I used to work on a database application stack which had a bunch of classes for database entities (People and Companies, say) each inheriting from a DBEntity class; and other classes, inheriting from the database-facing classes, to format those entities for display (DisplayPeople, DisplayCompanies, etc.) The display classes each had to inherit from the database-facing classes, and each had its own particular display needs, but there were also, unsurprsingly, a lot of display functions in common. It would have been very useful to be able to define a DisplayEntity class from which each of the display classes could have inherited, using the common methods when applicable and defining their own methods when needed.
