• Fixed named color compression to apply only when an identifier is guaranteed to be a color. Used CSSTree's feature to determine the meaning of a part of a value based on W3C specs. No more false positive matches like Arial Black, and with no hacks ;)
• Added lifting of @keyframes to the beginning of style sheet
• Added removal of @keyframes, @media and @supports with no prelude
• Added removal of duplicate @keyframes (#202)
• Added new option forceMediaMerge to force media rules merging. It's unsafe in general, but works fine in many cases. Use it on your own risk (#350)
• Bumped CSSTree to 1.0.0-alpha23
