For the Eclipse PHP developers out there anxiously awaiting the next major release of the extension, you'll have to wait just a bit longer. Max Horvath mentions a few of the reasons why:

As expected by many, Eclipse PDT's next major release has been postponed. While two milestones couldn't be released, it became clearer and clearer that the release date of September 15th 2008 couldn't be met.

The new deadline has been set though - December 29th, 2008. New improvements in this release will include a type hierarchy view, new PHP explorer functionality, code templates and a code assist for dynamic variables. There was also a large change to the API that set things back a bit.
