Electromancer at Ogaminig has written a humorous article about the recent changes in appearance of the succubus, a warlock pet. For those unaware of the changes the article highlights them all. Here's a quote from the article:

One feature you may miss is how much the horns, wings, legs, and tail have changed. The Succubus’s horns are now larger and more hellish looking and are spaced slightly further apart making her feel more like a demon than a deformed cartoon character. The wings are actually slightly smaller and have a worn look, with larger holes and more ripping in them and they sit much higher on her back, a sign of sexual potency in hell. The entire lower leg from just below the kneecap down now has the lizard scale like look to it and has become slightly thinner and is covered in tiny barbs, something no man should ever have to deal with in a girlfriend. Even her tail has changed, taking on less of an arrow tip tail and more of a thorn covered tail, another turn off in a girlfriend. They all have taken on a much darker color, as well. These features are something you would have noticed if you saw a Succubus on a regular basis, but most people probably wouldn’t notice these changes very much.
