This demo site is now running the pre-release version of vBulletin 5.4.2.
I have set it to dislay only the new 'dark' style so everyone can see what it will look like. I've left it pretty much 'default' for now to avoid confusion. I'll play with it later.
Anything that may be a bug related to the dark style, please log it in the vBulletin Tracker as soon as possible.
