The 0.105 release is available now. It includes a reworked version of Miriam Mono family, which is now OpenType and has diacritics support developed by Yoram Gnat.
In addition, an issue with “Hataf” diacritics in David and Miriam was resolved.
As usual, the fonts can be downloaded from the Culmus project site: http://culmus.sourceforge.net. Enjoy using them!
