General:
* The \input primitive in all TeX engines, including tex, now also accepts a
group-delimited filename argument, as a system-dependent extension. The usage
with a standard space/token-delimited filename is completely unchanged. The
group-delimited argument was previously implemented in LuaTeX; now it is available
in all engines. ASCII double quote characters (") are removed from the filename,
but it is otherwise left unchanged after tokenization. This does not currently
affect LaTeX’s \input command, as that is a macro redefinition of the standard
\input primitive.
* New option –cnf-line for kpsewhich, tex, mf, and all other engines, to support
arbitrary configuration settings on the command line.
* The addition of various primitives to various engines in this and previous years
is intended to result in a common set of functionality available across
all engines.
epTeX, eupTeX: New primitives \Uchar, \Ucharcat, \current(x)spacingmode, \ifincsname;
revise \fontchar?? and \iffontchar. For eupTeX only: \currentcjktoken.
LuaTeX: Integration with HarfBuzz library, available as new engines luahbtex
(used for lualatex) and luajithbtex. New primitives: \eTeXgluestretchorder,
\eTeXglueshrinkorder.
pdfTeX: New primitive \pdfmajorversion; this merely changes the version number
in the PDF output; it has no effect on any PDF content. \pdfximage and similar
now search for image files in the same way as \openin.
pTeX: New primitives \ifjfont, \iftfont. Also in epTeX, upTeX, eupTeX.
XeTeX: Fixes for \Umathchardef, \XeTeXinterchartoks, \pdfsavepos.
Dvips: Output encodings for bitmap fonts, for better copy/paste capabilities.

Otherwise, existing SHA1 digests verified and found to be the same on
the machine holding the existing distfiles (morden). All existing
SHA1 digests retained for now as an audit trail.
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.
