Anyone install yet? Any problems?
That update fixed a problem where some users couldn't preview or publish their files. I haven't heard any reports of that breaking something in a file, but if you do run into an issue we're here to help. You'll see all the items fixed noted in our version history.
You can always post here in ELH, or reach out to our Support Engineers directly. They can work with you one on one to troubleshoot and provide a rollback to an earlier version if needed.
