Yes that's right, build 42757 was released on the 23rd and is the first public RC of Workstation 6.0. Aside from the usual slew of bugfixes, the biggest deal for anyone using it is that debugging is finally configurable! In the betas, debugging was set to Full and there was nothing you could do about it, which is reasonable enough for a beta I guess. Now it's set to 'none' by default :-)
It's also a whopping 280MB download... the current version of Workstation 5.x is only ~90MB!
