+Version 1.21 released
+=====================
+
+	* NEWS, REVISION, VERSION, doc/groff.texinfo, doc/webpage.ms:
+	Updated.
+	* aclocal.m4, configure: Regenerated.
+
+2010-12-31  Werner LEMBERG  <wl@gnu.org>
+
+	* doc/webpage.ms: Updated.
+
+2010-12-31  Werner LEMBERG  <wl@gnu.org>
+
+	* configure: Regenerate with autoconf 2.67.
+
+2010-12-31  Werner LEMBERG  <wl@gnu.org>
+
+	Update various scripts.
+
+	* config.guess, config.sub: Update from `config' repository.
+	* install-sh, mkinstalldirs: Update from `gnulib' repository.
+
+2010-12-31  Werner LEMBERG  <wl@gnu.org>
+
+	Update texinfo.tex.
+
+	* doc/texinfo.tex: Update from `texinfo' repository.
+
+2010-12-30  Werner LEMBERG  <wl@gnu.org>
+
+	Call texi2dvi with correct makeinfo binary.
+
+	* doc/Makefile.in (.texinfo.dvi, .texinfo.pdf): Use $(MAKEINFO).
+
+2010-12-30  Werner LEMBERG  <wl@gnu.org>
+
+	Documentation updates.
+
+	* NEWS, PROBLEMS, MANIFEST: Update.
+
+2010-12-26  Werner LEMBERG  <wl@gnu.org>
+
+	Speed up troff.
+
+	* src/include/ptable.h (PTABLE): Make hash tables much more sparse
+	by changing the ratio `FULL_NUM/FULL_DEN' from 2/3 to 1/4.  This
+	increases the allocated memory by about 200kByte (which is nothing
+	today) but assures that there aren't extremely long searches for a
+	free hash slot in case that the hash function doesn't return a free
+	one.  Due to the nature of the entries in uniuni.cpp, the used hash
+	function in ptable.cpp is not optimal, but using a sparse array
+	compensates this.
+
+2010-12-20  Werner LEMBERG  <wl@gnu.org>
+
+	Replace patch from 2010-12-18 with a much faster implementation.
+
+	* src/roff/troff/node.h (node): Add virtual function
+	`get_break_code'.
+
+	* src/roff/troff/node.cpp (inter_char_space_node): Remove class
+	completely.
+	(glyph_node::merge_glyph_node): Restore previous version.
+
+	(break_char_node): Add `prev_break_code' field and update
+	constructors.
+	(node::get_break_code, break_char_node::get_break_code): Implement.
+
+	(node::add_char): Pass remaining cflags values.
+
+	(break_char_node::add_self): Use the logic of the now deleted
+	`inter_char_space_node::add_self' function to insert a space node if
+	necessary.
+
+2010-12-20  Daiki Ueno  <ueno@unixuser.org>
+
+	A new try to not changing srcdir if building in separate builddir.
+
+	Makefile.in ($GNULIBDIRS): Disable calls to autoconf and friends.
+
+2010-12-20  Werner LEMBERG  <wl@gnu.org>
+
+	Speed up access to cflags values.
+
+	We now recompute the cflags values for all charinfo objects if
+	`.class' has been called.
+
+	* src/roff/troff/charinfo.h: Add external references to `class_flag'
+	and `get_flags'.
+	(charinfo): `get_flags' no longer has a return value.
+	(charinfo::overlaps_horizontally, charinfo::overlaps_vertically,
+	charinfo::can_break_before, charinfo::can_break_after,
+	charinfo::can_break_after, charinfo::ends_sentence,
+	charinfo::transparent,, charinfo:ignore_hcodes,
+	charinfo::prohibit_break_before, charinfo::prohibit_break_after,
+	charinfo::inter_char_space): Call global `get_flags' only if
+	necessary.
+	(charinfo::add_to_class): Set `class_flag'.
+
+	* src/roff/troff/input.cpp (class_flag): New global flag.
+	(charinfo::charinfo): Call `get_flags' member function.
+	(get_flags): New global function which iterates over all entries in
+	the charinfo dictionary.
+	(charinfo::get_flags): Set `flags' directly.
+
+2010-12-19  Werner LEMBERG  <wl@gnu.org>
+
+	Protect `.class' against cyclic nesting.
+
+	* src/roff/troff/charinfo.h (charinfo::contains): Add optional
+	boolean argument.
+	* src/roff/troff/input.cpp (define_class, charinfo::contains): Check
+	for cyclic nesting.
+
+2010-12-18  Werner LEMBERG  <wl@gnu.org>
+
+	Improve CJK support with new values for `.cflags'.
+
+	This patch introduces three new values to `.cflags':
+
+	  don't break before character: 128
+	  don't break after character:  256
+	  allow inter-character break:  512
+
+	They are handled differently if compared to other cflags values:
+
+	  (1) hcode values are completely ignored
+	  (2) similar to kern values, and contrary to the other cflags
+	      values, troff looks at pairs of characters to decide whether a
+	      break gets inserted
+
+	A yet-to-be-written patch should add inter-character spacing if
+	those flags are active; currently, only zero-width breakpoints are
+	inserted.
+
+	* src/roff/troff/charinfo.h (charinfo): Change type of `flags' to
+	`int'.  Update callers accordingly.
+	New enum values `DONT_BREAK_BEFORE', `DONT_BREAK_AFTER', and
+	`INTER_CHAR_SPACE'.
+	New member functions `prohibit_break_before',
+	`prohibit_break_after', and `inter_char_space'.
+	* src/roff/troff/input.cpp: Updated.
+
+	* src/roff/troff/node.cpp (inter_char_space_node): New class similar
+	to kern_pair_node, collecting charinfo entities with the
+	abovementioned cflags values.
+	(break_char_type): Add new enum values.
+	(glyph_node::merge_glyph_node): Handle abovementioned cflags values
+	and emit an `inter_char_space_node' if necessary.
+
+	* tmac/ja.tmac: Use new cflags values.
+
+	* doc/groff.texinfo, NEWS, man/groff_diff.man: Document new values.
+
+2010-12-18  Werner LEMBERG  <wl@gnu.org>
+
+	Remove compiler warning.
+
+	* src/libs/libgroff/relocate.cpp (msw2posixpath): Remove redundant
+	dereferencing.
+
+2010-12-16  Daiki Ueno  <ueno@unixuser.org>
+
+	Don't change srcdir if building in a separate builddir.
+
+	* Makefile.in ($GNULIBDIRS): Copy configuring stuff of gnulib if
+	necessary.
+
+2010-12-15  Werner LEMBERG  <wl@gnu.org>
+
+	Fix compilation problem.
+
+	This issue happens with gcc 4.2.4.
+
+	* src/roff/troff/node.cpp (node::~node): Move to...
+	* src/roff/troff/node.h: Here.  This ensures that the inline
+	member function is publicly visible.
+
+2010-12-15  Werner LEMBERG  <wl@gnu.org>
+
+	Remove unused code.
+
+	* src/roff/troff/node.cpp, src/roff/troff/node.h
+	(space_node::space_node): Remove unused constructor.
+
+2010-12-15  Werner LEMBERG  <wl@gnu.org>
+
+	Use enum to increase readability.
+
+	* src/roff/troff/node.cpp (break_char_type): New enum.
+	(break_char_node::add_self, node::add_char): Use it.
+
+2010-12-13  Daiki Ueno  <ueno@unixuser.org>
+	    Werner LEMBERG  <wl@gnu.org>
+
+	Add wide character support to grotty.
+
+	This is a huge patch, mainly by adding the gnulib infrastructure in
+	a separate directory tree (in `src/libs/gnulib/lib') for its
+	`wcwidth' module.  However, the actual changes to native groff
+	source files are just a few lines.
+
+	* Makefile.comm (INCLUDES): Updated.
+	(LIBGNU): Define.
+
+	* Makefile.in (NOMAKEDIRS): Updated.
+	(GNULLIBDIRS): Define.
+	(DISTDIRS): Add GNULLIBDIRS.

+	* src/roff/troff/Makefile.sub (XLIBS): Add LIBGNU.
+	* src/roff/troff/input.cpp (main): Set LC_CTYPE.
+
+	* src/devices/grotty/Makefile.sub (XLIBS): Add LIBGNU.
+	* src/devices/grotty/tty.cpp (main): Set LC_CTYPE.
+
+	* src/libs/gnulib/*: New files.  The import was done as follows:
+
+	  . Call
+
+	      gnulib-tool --create-testdir \
+	                  --dir=src/libs/gnulib \
+	                  wcwidth
+
+	    to get a testbed.
+
+	  . Manually move directories src/libs/gl{lib,m4} to
+	    src/libs/{lib,m4}, and do s/gllib/lib/ and s/glm4/m4/ everywhere
+	    to `convert' the gnulib testbed to a standard gnulib
+	    configuration as maintained by gnulib-tool.
+
+	  . Call
+
+	      gnulib-tool --add-import \
+	                  --dir=src/libs/gnulib \
+	                  wcwidth
+
+	    to update everything.
+
+2010-12-13  Werner LEMBERG  <wl@gnu.org>
+
+	`.class' must not emit empty lines.
+
+	* src/roff/troff/input.cpp (define_class): Add missing `skip_line'
+	calls.

+2010-12-06  Colin Watson  <cjwatson@debian.org>
+	    Daiki Ueno  <ueno@unixuser.org>
+
+	Implement support for character classes.
+
+	This patch uses standard C++ headers, contrary to the rest of groff.
+	Ideally, everything in groff should be updated to do the same.
+
+	* src/include/font.h (glyph_to_unicode): New function.
+
+	* src/libs/libgroff/font.cpp (glyph_to_unicode): Implement it.
+	(font::contains, font::get_code): Use it.
+
+	* src/roff/troff/charinfo.h: Include <vector> and <utility>.
+	(charinfo): New members `ranges' and `nested_classes'.
+	New member functions `get_unicode_code' and `get_flags'.
+	New member functions `add_to_class', `is_class', and `contains'.
+	(charinfo::overlaps_horizontally, charinfo::overlaps_vertically,
+	charinfo::can_break_before, charinfo::can_break_after,
+	charinfo::can_break_after, charinfo::ends_sentence,
+	charinfo::transparent,, charinfo:ignore_hcodes): Use `get_flags',
+	which handles character classes also.
+
+	* src/roff/troff/input.cpp (char_class_dictionary): New global

+	  x init
+	  p1
+	  Dt
+
+	* src/libs/libdriver/input.cpp (get_integer_arg): Emit a fatal error
+	on a non-integer argument, bringing the code into line with the
+	behaviour documented in the header comment.
+	(get_possibly_integer_args): Terminate the loop on a non-integer
+	argument.

+	[troff]: Fix hyphenation problem with kerned letters.
+	Problem reported by Steve Izma <sizma@golden.net>.
+
+	* src/roff/troff/node.cpp
+	(kern_pair_node::add_discretionary_hyphen): Compute `tf' using the
+	first node, `n1'.  `n2' might be another kerning node, and the
+	`get_tfont' member function isn't defined then.
+
+2009-09-01  Michael Cain  <mcain6925@comcast.net>
+
+	[pic] Fix a border case for arc computation.
+
+	* src/preproc/pic/object.cpp (object_spec::make_arc): It can happen
+	that test `radius < d' in the loop is satisfied, but the difference
+	in the two values is on the order of 1e-10.  If `radius' is small,
+	doubling the value can lead to a fairly gross error.
+
+	The original code appears to have been intended to deal with the
+	situation when radius is orders of magnitude less than `d'.  The
+	replacement code simply assigns `radius' the smallest value that
+	avoids problems with the floating point code further on in the
+	routine.
+
+2009-08-14  Roger Leigh  <rleigh@debian.org>
+
+	* man/groff_char.man: Fix white heart and diamond unicode values.

+	pic: Fix handling of nested positions.
+	Reported by Doug McIlroy <doug@cs.dartmouth.edu>.
+
+	* src/preproc/pic/pic.y: Split `expr' into `expr_lower_than' and
+	`expr_not_lower_than' so that we can handle
+
+	  (1/3)<(1/2)<foo,bar>,baz>
+
+	correctly.  Without the patch, `(1/3)<(1/2)' is handled prematurely
+	as a comparison.

+
+	* configure.ac: Read `VERSION' and `REVISION' files to provide
+	proper values for AC_INIT.
+	* Makefile.in: Use `@datarootdir@' and `@docdir@' so that
+	configure's `--datarootdir' and `--docdir' options are honoured.
+	Documentation is now by default installed into something like
+	`/usr/local/share/doc/groff-1.20.1'.
+

+
+2009-02-14  Werner LEMBERG  <wl@gnu.org>
+
+	Implement a leading spaces macro request, `lsm', in analogy to
+	`blm'.
+	Implement two new number registers, \n[lsn] and \n[lss], which hold
+	the number of spaces and the horizontal space, respectively, which
+	would be inserted if the macro registered by `lsm' wasn't called.
+
+	* src/roff/troff/input.cpp (leading_spaces_macro_name,
+	leading_spaces_number, leading_spaces_space): New global
+	variables.
