改善了和 CJK 的匹配
all weights: the glyphs are been scaled to become exactly 0.5 em² wide (1024) so they are compatible with CJK (Chinese/Japanese/Korean) characters, where every character are exactly 1 em² wide (2048)
all weights: all the arrows, planned by Unicode until now, are been designed
Regular: improved the design of U+2200 – U+22FF Mathematical Operators set added the U+2200 – U+22FF Mathematical Operators set added the U+2980 - U+29FF Misc. Mathematical Symbols-B set added the U+2A00 – U+2AFF Supplemental Math Operators set under the precious supervision of Pierre Le Marre
all weights of PragmataPro: improved the design of ! m + - < = > ~ ¡ ÷
all weights of PragmataPro: added some important ligatures, changed the design of ligatures that includes < and >
