Version 2.90 adds colour to the Initial Forms and completes the Latin Extended Additional, Number Forms and Dingbats Character Sets. The 7-zip archive also includes smaller Web and WOFF versions with only a few symbols. The web versions still contain the Coloured Glyphs for Stylistic Alternates, which can currently be viewed only in Firefox.
Updates to TTFautohint seem to have fixed the issues with hinting.
See this tutorial thread to see how the coloured glyphs were created.
