I'm not sure if this is new to V38.2, but I just noticed it. I didn't see it as a documented "What's new" feature/enhancement in the Knowledge Center, so I'm going to call it a hidden gem (unless I've somehow been missing it for a long time- maybe someone else can confirm?).
There is an attachment image viewer for viewing image attachments in-product now. Very cool! Animation of opening it, and ability to switch through several attached images in it is awesome. Much better than downloading images manually to open them.
Thought I'd share in case anyone else was unaware of it...
