I noticed there was a relatively current open source download package for VMware Studio, so I downloaded it, hoping there were instructions on applying the new software to the appliance. The download was a tar.gz file, which appears to include source code for those OSS packages.
So, I am concluding that my hope that this was an update to VMware Studio was unfounded.
Is there any news, at all, about plans to update VMware Studio? It is obvious that a VMware-internal tool exists as they use it to create their own appliances which appear to have fixed some issues, such as IE10 access.
