The major internal change in this release is the file structure change for the development files. We now make use of a Makefile to generate ttfs and do other things.
Updates include addition of double struck letters, letterlike symbols, arrows and some mathematical symbols to Serif, Ogham and Yijing symbols to Sans. Hinting instructions were added to some Cyrillic letters in Sans. Also various fixes and adjustments were done to Cyrillic in Serif and other glyphs.
