Lights, turbulence, trails … Yayyyyyyyyyyyyyyyyyyyy 
I’m hesitant to update, is it really as bug-ridden as the comments on the blog make it appear?
Haven’t encountered many bugs so far, and the ones I had were mostly just little interface glitches, nothing more. But as with any release, I’d probably recommend waiting a bit before diving in, just to be safe. 
I think the artist tools and particle themselves are probably in good shape for testing out the new tools, maybe currently not a few thirdparty plug-ins. But there are probably bigger bugs specific to chain linked production related aspects.
So if you are mid-production, maybe wait on updating 
And CC0 rights to some nice fx flipbooks.
