Most of our templates aren't "beautiful" ;0) - they mimic the look of an email sent from Outlook, and they look the same as before. However, I did notice that one of our more commercial looking templates has its headline, bullets and body copy compressed vertically like the leading has been decreased. When I look at the same template in Outlook, the leading is increased. Not sure what might have caused this, but a couple of months ago, I noticed that the overall display of text in Salesforce changed and appeared to be smaller / more compressed.
