Mark Caneso has released a new humanist sans serif family, Ratio. Looks to be a very versatile face, with certain details recalling both Whitney and Auto. No word on the site regarding embedding/licensing restrictions.
Update: Mark sent me his EULA, which allows for several popular forms of embedding, including sIFR, Cufón and font-face. Very good news, especially given some of the other faces he’s working on.
