The new version is supposed to come out any time now, but they are emailing links for those that want to download the old version.  It may be old, but it is a damned good set of photoshop (possibly lightroom, I don't know) plugins.

Apparently they released the updated DXO Nik Effects and is $50 for the rest of the month before going up to $70.  They completely overhauled and upgraded the code, brought it up to current standards, added tweaks/tools, but as a whole the plugins are largely the same.  It's just been optimized for new systems/tech, built in Adobe CC compatibility including LR, and tuned.

Considering the old version crashes fairly often I'll have to think on it.

Got it yesterday, too busy on shoots to play with it right now.  I opened one image in color efex and added like 5 random filters and processed it, seems to be just as fast as the last version.

I'll try to play with it more today
