I like this new window - render history. You can see all your recent renders as thumbnails and click them for instant review/comparison. If you're a material or lighting tweaker like me, this is a really useful tool.

Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
