Hello,
The schedule of the "summer" release seems to be pushed to September, but we're making beta in the mean time. And, there is a new beta installer for Windows:
http://squeakland.org/content/installers/Etoys-4.0.2257-Beta-Win.exe
It contains the new VM, which most notably allows the user to see the Quick Guide contents even after loading a project from a server and security sand boxing is enabled. Also, the image updated with some bug fixes.
Also on the download page:
http://squeakland.org/download/
you can find other beta versions.
Please give them a try and let us know if you find some problems.
