"There is a new version" notice, I have the newest?

When I start Vs.Php (which I downloaded just moments ago) I get a dialog with "There is a new version available".

When I press the Download -button, the page http://www.jcxsoftware.com/jcx/vsphp/downloads opens:

Version 2.4.3.4448 released on February 27, 2008

The MSI file used for installation was vsphp_en_2008_2.4.3.4448.msi.

The Help -> About says:

VS.Php 2.4 for Visual Studio 2008 version 2,4,2,4448.
