There have been a fair number of questions about when Solid Edge ST6 would be announced. I'm just getting on the distriburion lists around here, and although this news is a week old, some of you may not have heard yet. The following info comes from Fred White of support:
Solid Edge ST6 released to manufacturing on 07/19/2013. Solid Edge ST6 will be delivered automatically to customers with a current Maintenance Contract. Based on current schedules, English maintenance kits should begin shipping early August, and additional Languages will follow in the coming weeks.
