Peter,
The next test version of VMD has a bunch of new capabilities in it that require
video drivers that are as-yet not available to the general public. I have test drivers
but they are restricted by NDA. When the new video drivers are released to the public,
I will be posting new test builds of VMD. The current expectation I have is that
the new drivers will become available in mid-September, and then I will be able to
post the latest test builds of VMD for people to try. Although VMD will run (in a
less featureful state) without the upcoming video drivers, VMD itself is also compiled
against various shared libraries, and I'm expecting production versions of some key
shared libraries to become available contemporaneously with the video drivers.
The VMD release will follow the normal progression from alpha to beta and then a
final release, but the beta releases won't happen until sometime after the
new video drivers and associated shared libraries become publicly available.
I know everyone is getting anxious. ;-)
Best regards,
John Stone
