2018-02-04  Jonathan Kew <jfkthame@gmail.com>

	* NEWS: Update for 0.99999.

2018-02-03  Jonathan Kew <jfkthame@gmail.com>

	* Bump version number to 0.99999, aiming for the TL'18 release.
	Fix issues reported on https://sourceforge.net/p/xetex/bugs
	* xetex.web, xetex.ch: Patch from Hironori Kitagawa to
	integrate prim_eqtb into eqtb. Fixes issue where
	\primitive\vrule\q incorrectly swallows the \q instead of
	giving an error. Fixes #143.
	* xetex.web: Patch from Hironobu Yamashita for \strcmp and
	\mdfivesum errors. Fixes #144.
	* xetex.web: Patch from Hironobu Yamashita for \uchyph with
	native fonts. Fixes #145.
	* XeTeX_ext.[ch]: Patch from Hironobu Yamashita to properly
	close input pipes. Fixes 147.
	* xetex.web: Leave text as UTF-16 in trick_buf for better
	error context printing. (Mostly) fixes #146.
	It's still possible that error context could include half of
	a supplementary-plane character (i.e. an unpaired surrogate).
	Should be a lot less likely, and less troublesome than broken
	UTF-8, however.
	* XeTeXFontMgr.cpp, XeTeXFontMgr.h: Convert optical size info
	in OpenType 'size' feature from PostScript to TeX points.
	Note that this will change behavior for existing documents
	that use OpenType fonts from optically-sized families, and
	depend on XeTeX choosing the appropriate face for a given
	size: the boundaries at which face selection changes will be
	slightly shifted (corrected) from how earlier versions behaved.
	* xetex.web: Avoid prematurely merging following text with the
	no-break text of a \discretionary. We don't want to combine
	text after \discretionary{A}{B}{C} into the same node as the
	(trailing node of the) no-break parameter {C}, because this
	would result in following text being lost in the case where
	the discretionary break is taken. When this happens, its
	no-break text (recorded as a count of nodes) is supposed
	to be skipped over, but if we've combined following characters
	with the trailing node, they will also be (incorrectly)
	skipped. Fixes #137.

2018-01-17  Akira Kakuto  <kakuto@fuk.kindai.ac.jp>

	* am/xetex.am (OBJCXXFLAGS) [XETEX_MACOSX]: add -std=c++11.

2017-12-22  Akira Kakuto  <kakuto@fuk.kindai.ac.jp>

	* image/jpegimage.c: If j_info->xdpi and j_info->ydpi are not
	determined in some JPEG format, they are assumed to be 72.0
	in order to avoid division by zero.

2017-11-07  Jonathan Kew  <jfkthame@gmail.com>

	* XeTeX_ext.c: Guard against out-of-range result from UTF-8
	decoding, and return U+FFFD Replacement Character instead
	to avoid a crash for invalid inputs (from A. Kakuto).

2017-09-24  Hironori Kitagawa  <h_kitagawa2001@yahoo.co.jp>

	* xetex.web: Avoid overwriting prim_* entries by primitive().

2017-09-05  Karl Berry  <karl@tug.org>
        and Akira Kakuto  <kakuto@fuk.kindai.ac.jp>

	* xetexdir/XeTeX_ext.c (IS_SPC_OR_EOL): new macro.

2017-04-22  Jonathan Kew  <jfkthame@gmail.com>

	* xetex.web, xetex_version.h, NEWS: Fixed long-standing bug that made
	\ifcat\span...\fi (and similar constructions with \cr, \crcr) behave
	incorrectly. Also fixed initialization of \delcode values for
	supplementary-plane characters. version 0.99998.

	because asynchronous outputs of XeTeX and xdvipdfmx are messy.

	* xetex.web, NEWS: sync with the upstream.

2015-11-06  Akira Kakuto  <kakuto@fuk.kindai.ac.jp>
