We've previously reported on CSS vendor prefixes, including the W3C CSS Working Group's initial suggestion browsers could start supporting other vendors' prefixes and then Opera confirming that it would alias a number of WebKit prefixes within its own rendering engine. However, minutes from the latest CSS WG meeting have pushed things the other way for CSS Transforms, Transitions and Animations.
In the minutes, there was rapid consensus on the decision to enable these things to be unprefixed going forwards. Google's Tab Atkins said he was "morally approving of the move", and Opera software engineer Florian Rivoal argued it was "painful that they're prefixed," adding: "now [the] cat is out of [the] box, yes". Mozilla developer David Baron followed up with: "I think we should unprefix as well. Would also like to see the specs move forward."
