Another Amiri font release in less than month (release early, release often ;). The main feature of this release is brand new bold and bold slanted fonts, so now we cover the four common styles, though more work on polishing them still needed. Check News file for more detailed changes of this release (Arabic, English)

إصدارة جديدة من الخط الأميري مع قفزة جديدة في رقم الإصدارة لتوضيح الانتقال من مرحلة ألفا إلى مرحلة بيتا :) (أرقام إصداراتي لامنطقية، لكن هكذا الحياة).

Yet another Amiri font release with yet another jump in version number, this time to mark the move from alpha stage to beta stage :) (my versioning scheme makes no sense, but so is life).

إصدارة جديدة أخرى من الخط الأميري، هذه المرة مع دعم مكتمل -نوعا- ما للرسم القرآني، وهي آخر ميزة مهمة كانت تنقص الخط، وربما بعد إصدارتين أو أقل يدخل الخط إلى مرخلة بيتا تمهيدا للإصدارة النهائية.

Yet another developmental release of Amiri font, this time featuring a, more or less, complete Quranic support, which fixes the last major issue with the font, and I think it is only a couple of more alpha releases before it is ready to enter beta stage.

Another developmental release of Amiri font, marking a major developmental milestone.

Amiri was developed using a novel, and natural, approach of separating dots from base of the glyph and treating them as diacritical marks (which what they really are), this allowed much more flexibility than the more conventional approach of treating the dot and its base as a whole.

In the early developmental stages things were fine, but as the need for more complex tasks surfaced, things were getting

Though v1.010 was promised to be the last release, I'm resuming work on the fonts, so here is a new beta of XITS fonts, featuring mainly support for right-to-left math which have been the main motivate behind the project, though never made it to any of the released versions (only supported by LuaTeX for now, more on that later).

First attempts of Arabic math typesetting. Using ConTeXt MkIV, LuaTeX and my experimental XITS Math font.

I was trying to change the math font used in plain TeX (as opposed to LaTeX or ConTeXt), but I didn't seem to find it documented any where, apparently it is so obvious for TeXperts to be even documented. Anyway, I figured it out and I'm documenting it here so I don't have to search it again.

Set font families 0-3 to the new font, as follows:
0: math text ("sin", "cos", numbers, etc.)
1: math italic ("x", "y", "z", etc. don't have to be italic at all e.g. Euler)
2: math symbols
3: math extensions
\textfont: normal size font
\scriptfont: font for sub/super script
