Changes:
* Add a real error message when a font cannot be found.
* Add "Letters=Random" feature.
* Fix bug in which "Unknown feature `'..." warnings
were shown in the log file.
* Some small documentation improvements.
Changes:
* Internal changes for luatexbase v0.3.
* Bug fix when \itdefault is "sl" rather than "it".
E.g., when using the "slides" class.
* Minor internal changes, including merging some code from unicode-math.
* New documentation for defining custom kerning and ligatures
when using LuaLaTeX.
* Fix bug when defining bold italic fonts by filename.
* Avoid infinite loop when the Latin script is requested for a font
that does not contain it. TODO: a suitable fallback script should be
chosen; right now we just ignore the script selection.
* Fix for bug introduced in the last release:
small caps weren't being automatically selected correctly
* Fix for colours bug introduced in the last update
* Fix for for bad interaction with LuaLaTeX and fallback fonts
(such as using \slshape when no slanted font specified)
* Behaviour/messaging improvement when scripts/languages are requested
that do not exist in the font
* Fix bug with detecting font features/scripts in some cases with:
- `\fontspec_if_feature:n(TF)`
- `\fontspec_if_language:n(TF)`
- `\fontspec_if_current_script:n(TF)`
- `\fontspec_if_current_language:n(TF)`
* Some messages in the log file are improved
* Code for "visible space" fixed for LuaLaTeX use
* Lots of internal changes to bring the implementation closer
to being "native expl3".
Fontspec is a package for XeLaTeX. It provides an automatic and
unified interface to feature-rich AAT and OpenType fonts through the
NFSS in LaTeX running on XeTeX. XeTeX (the successor to TeX-GX) is a
TeX-variant (originally for Mac OS X, but now available in the major
distributions for other platforms, too) that accepts unicode input and
can access system fonts directly.
