Changes since 0.40.2:
* Fix two string vs. toks bugs in the lua node interface:
whatsit,annot and whatsit,startlink data assignments were
made directly as strings instead of being converted to tokens.
* Sometimes pdf.print() could be used before the proper structures
were initialized.
* There was a bug in the type codes for the lua package filter
callback: wrong extra info was passed to lua for the alignment
and vsplit cases.
* The math parameters \Umathlimitdownvgap, \Umathlimitdownbgap,
and \Umathlimitdownkern have been renamed to \Umathlimitbelowbgap,
\Umathlimitbelowvgap, and \Umathlimitbelowkern to be more
consistent with the other parameter names.
* The embedded MPlib is now 1.204.
* Handling of UTF-8 hyphenation exceptions has been fixed.
* There were a number of typos in the manual.
* One of the internal print functions accidentally encoded its
argument string to UTF-8 even though it was already UTF-8.
* Some of the log and terminal UTF-8 output was gibberish.
* \the\textfont0 returned a number instead of doing a font
switch.
* A set of portability fixes for the AIX compiler from Vladimir
Volovich.
* A set of fixes to the synctex support.
* A patch to the build script to prevent installed X11 headers
from being required.
* Some weave (web syntax) fixes from Manuel Pégourié-Gonnard.
* A simplification in luatex.ch (it is now less verbose
about the web2c-specific extensions) from Karl Berry.
* A fix in the handling of UTF-8 (input) file names.
* Hyphenation exceptions were case sensitive in 0.40.2.
LuaTeX is an extended version of pdfTeX using Lua as an embedded
scripting language. The LuaTeX projects main objective is to provide
an open and configurable variant of TeX while at the same time
offering downward compatibility.
