pdfTEX: Support JPEG Exif as well as JFIF; do not even emit a warning if
\pdfinclusionerrorlevel is negative; sync with xpdf 3.04.
LuaTEX: New library newtokenlib for scanning tokens; bug fixes in the normal
random number generator and other places.
XeTEX: Image handling fixes; xdvipdfmx binary looked for first as a sibling
to xetex; internal XDV opcodes changed.
MetaPost: New numbersystem binary; new Japanese-enabled upmpost and
updvitomp programs, analogous to up*tex.
Infrastructure: The fmtutil script has been reimplemented to read
fmtutil.cnf on a per-tree basis, analogous to updmap. Web2C mktex* scripts
(including mktexlsr, mktextfm, mktexpk) now prefer programs in their own
directory, instead of always using the existing PATH.
The primary LaTeX package for the support of the inclusion of graphics
generally produced with other tools. This package aims to give a
consistent interface to including the file types that are understood
by your printer driver.
