Hussar Preview's next version will release in 2016 as stated in the most recent CiSf news, but I didn't post many details about it then, so here are some details.
Hussar Preview version 2.29 is going to be a large update, with many redesigned and tweaked characters, plus many additions.
Some changes are listed below.
Addition of new characters including the Polish Kreska accent, which is used in Polish (the acute is commonly used instead by most designers, but they are different), Polish Kreska accented letters (A, O, N, S, & Z, both upper and lowercase), subscript numerals, and more.
Tweaks and redesigns of characters, including the lowercase x, Kotwica symbol, a new number 4, uppercase N, most of the Runic alphabet, lowercase a, Welsh LL digraphs (upper & lowercase), Grave and acute accents, and many more.
These are just some of the changes so far, many more are in the works that will be completed before it is ready for release.
Merry Christmas, Happy Hanukkah, Happy Holidays and Happy New Year from all of us @ Cannot Into Space Fonts.
