it into the normal PLIST.
VERSION 1.19.2
==============
Troff
-----
o Analogously to the .ft and \f pair, two new requests `gcolor' and
`fcolor' (which pair with \m and \M, respectively) have been added to
set the glyph and background colours.
o A new read-only, string-valued register `.sty' returns the name of the
current style.
o Two new conditional operators `F <name>' and `S <name>' have been added.
`F' is true if a font <name> exists. `S' is true if a style <name> has
been registered.
o Cyrillic characters have been added to the `utf8' and `html' output
devices.
Pic
---
o The `by' argument in a `for' loop can now be negative if it is additive.
For the multiplicative case, it must be greater than zero.
Eqn
---
o The following keywords aren't new but haven't been documented previously:
undef NAME (to undefine a macro)
copy "FILE" (a synonym for `include')
space n (to modify the vertical spacing before and after
an equation)
o The following macros aren't new but haven't been documented previously:
Alpha, ..., Omega (the same as `ALPHA', ..., `OMEGA')
ldots (three dots on the base line)
dollar (a dollar glyph)
o The following keywords have been extended. Again, this isn't new but
hasn't been documented previously:
col n { ... }
lcol n { ... }
rcol n { ... }
ccol n { ... }
pile n { ... }
lpile n { ... }
rpile n { ... }
cpile n { ... } (set vertical spacing between rows to N)
Grohtml
-------
o This device driver has been raised to beta stage; its set of tags should
be stable now.
o New command line option `-s' to set the base point size.
o New command line option `-S' to set the split level while generating
multiple files.
Grotty
------
o Experimental support for zero-width and double-width characters.
Gxditview
---------
o On platforms which have the X Window System this program is now built and
installed automatically.
Xtotroff
--------
o This program to create font definition files for xditview isn't new but
hasn't been installed previously.
Groffer
-------
o A security problem (reported as CAN-2004-0969) has been fixed.
Gdiffmk
-------
o A new script contributed by Mike Bianchi. It compares two groff, nroff,
or troff documents and creates an output with added margin characters
(using `.mc') to indicate the differences.
Pdfroff
-------
o A new wrapper script contributed by Keith Marshall to easily create PDF
documents with groff.
Macro packages
--------------
o ms.tmac
. Support for fractional point sizes: A value for the `PS', `VS', `FPS',
and `VPS' register larger than or equal to 1000 is always divided by
1000. For example, `.nr PS 10250' sets the document's font size to
10.25 points.
. The `Ds' and `De' macros provided in ms since groff version 1.19 have
been removed; the equivalent `DS' and `DE' macros should be used
instead. X11 documents which actually use `Ds' and `De' always load a
specific macro file from the X11 distribution (`macros.t') which
provides proper definitions for the two macros.
. The following registers have been added for improving layout control:
PORPHANS
Defines number of lines following `LP', `PP', `QP', `IP' or `XP' which
must be kept together, before any automatic page break.
HORPHANS
Sets number of lines of following paragraph which must be kept with a
heading, defined by `NH' or `SH', before any automatic page break.
GROWPS
Sets the first level of heading (set with `NH') which will keep the
same point size as body text.
PSINCR
Sets the point size increment for each level of heading (set with
`NH'), below the threshold level set by `GROWPS'; e.g., if
\n[PS] = 10, \n[GROWPS] = 3 and \n[PSINCR] = 2.0p, then `.NH 1' will
produce 14pt headings, `.NH 2' will produce 12pt, and all other levels
will remain at 10pt (because \n[PS] = 10).
. The `SH' macro now accepts a numeric argument, to make heading size
match that of `NH' with same argument value when the `GROWPS'/`PSINCR'
feature is enabled.
Please refer to the documentation of the ms package for other, minor
improvements.
o me.tmac
The section type set with the `++' request is available in the `_M'
register. This isn't new but hasn't been documented before.
o www.tmac
The `HR' macro no longer causes an empty line for non-HTML devices.
A new macro `HEAD' has been added to directly add data to the
<head>...</head> block.
New macros `OLS' and `OLE' to start and end an ordered list.
New macros `DLS' and `DLE' to start and end a definition list.
Pdfmark
-------
o A new macro package contributed by Keith Marshall which implements PDF
marks. This is in alpha stage currently.
Miscellaneous
-------------
o Two new keywords to the DESC file have been added which are needed for
grohtml: `image_generator' and `unscaled_charwidths'. The former gives
the name of the program which creates PNG images, and the latter makes
troff always use unscaled character widths.
