Subject: ANNOUNCE: DJGPP port of GNU Groff 1.22.3 uploaded (DJGPP 2.05 only).
Reply-To: djgpp AT delorie DOT com

This is a port of GNU Groff 1.22.3 to MSDOS/DJGPP.


   Groff is a document-formatting and typesetting package.  It belongs to an
   older generation of word-processing software that is not WYSIWYG; instead,
   you edit the document source with a text editor, intersperse the text with
   special directives that specify fonts and formatting parameters, and then
   submit the source to a batch processor which produces a ready-to-print or
   ready-to-read document.
   Groff includes the GNU implementation of the Unix-standard utilities troff
   and nroff, and their companions pic, eqn, tbl, soelim, and others.  It also
   includes many macro packages, including man, the package of macros for
   formatting man pages.
   The DJGPP port of Groff is mainly used to format man pages.



   DJGPP specific changes.
   =======================

   - Although all the DJGPP specific changes required to build the old groff-1.16
     port have found their way into the official release code of groff, this port
     requires some adjustments.  This is because most of the non-posix code added
     since then is very WIN32 centric and ignores pure DOS peculiarities specially
     in pipeline.c.  There are also some file names and directory names that are
     not SFN clean and need to be adjusted so that the binary package installs
     and works on plain DOS.

   - The content of the /arch/djgpp of the official release has been replaced by
     new files (config.bat, config.sed, config.site, etc).  The original files
     have been moved into /arch/djgpp/original.

   - Groff requires some support programs to be available.  If they have not been
     ported to DJGPP then the corresponding functionality will not be available.
     This concerns specially the functionality to convert man pages into pdf.

   - To configure and build this port a C++ compiler and the latest port of perl
     must be installed.

   - The build system of groff is not the standard one produced with autotools.
     This makes it very hard to adjust the DJGPP specific config files to the
     path assumptions made in the Makefile.ins and the directory tree used.  Due
     to this reason the package has not been configured at all but all script
     adjustments have been done to configure and compile the source code in the
     /_build.205 directory.  You should cd into the /_build.205 directory and
     configure the sources like this:
       ..\arch\djgpp\config ./..

   - Although some DJGPP/DOS specific fixes have been done to the various shell
     and perl scripts not all of them may be operational.  In this case you are
     alone.  If you are able to fix them, send a patch to me and it will be
     include in the next port of groff.

   - The default paths were groff and its programs search for fonts and other
     scripts have changed since groff-1.16.  The groff specific paths stored
     in the djgpp.env file no longer reflects this and needs to be adjusted
     accordingly.

   - There are no DJGPP specific user visible changes.

   - This is the first port that has been compiled using djdev205.  Starting
     with this port version I will no longer support neither djdev204 nor djdev203.

   - The port has been tested by using it.  I have used them only on WinXP.
     It has worked flawlessly.  I do not konw if this will ever be the case on
     FreeDOS.  I have never used/tested them in that environment.

   - The port has been configured and compiled on WinXP SP3.  There is no
     guarantee that this may be possible with any other DOS-like OS.  Due
     to the massive use of long file names it will not be possible to configure
     and compile without LFN support.  The port has been compiled using gcc520
     and bnu225br2.


   As usual, all djgpp specific files (diffs, README files, etc.) are stored in
   the /arch/djgpp directory.  The sources have not been configured due to the
   need of absolute paths.  Neitherless all scripts have been written to be used
   in the build directory called /_build.205.

   For further information about GNU Groff please read the info docs and NEWS file.



   This is an verbatim extract of the NEWS file (not every change announced may
   be available in the DJGPP port):

-------------------------------------------------------------------------------


VERSION 1.22.3
==============

Gxditview
---------

o X11 resources for `gxditview', which were previously installed in
   /usr/X11/lib/X11/app-defaults no matter which `prefix' was set, are
   now installed in appresdir=$prefix/lib/X11/app-defaults.  If
   `appresdir' is not a standard X11 resource directory, the environment
   variable XFILESEARCHPATH should be set to this path.  The standard
   default directories depends on the system `libXt'.  Common directories
   include:

    /usr/lib/X11/app-defaults
    /usr/share/X11/app-defaults
    /etc/X11/app-defaults

   Note that if the option `--with-appresdir' is passed to `configure',
   the `prefix' will not be added to `appresdir'.


Glilypond
---------

o This new preprocessor (contributed by Bernd Warken) allows embedding of
   code for GNU LilyPond (http://www.lilypond.org), a music typesetter.  The
   data gets automatically processed and embedded as EPS images.


Gperl
-----

o Bernd Warken contributed a new preprocessor to handle Perl code that can
   be evaluated and then processed by groff.


Gpinyin
-------

o Another preprocessor from Bernd Warken to pretty-print Pinyin syllables
   like `guo2wang2' as `guówáng'.


Pdfroff
-------

o The pdfroff utility script now activates its `--no-toc-relocation' option
   by default, unless a request similar to:

      .if !\n[PHASE] .tm pdfroff-option:set toc_relocation=enabled

   is invoked during input file processing; (`.if !\n[PHASE] ...' ensures
   that the effect of the `.tm' request is restricted to the document setup
   phase of processing, as pdfroff sets it to 1 or 2 in the output phase,
   but leaves it unset in the setup phase).

   The bundled `spdf.tmac' macro package, which implicitly activates
   `-mpdfmark' for `ms' macro users, ensures that TOC relocation is
   appropriately enabled, when the `.TC' macro is invoked.


Macro Packages
--------------

o The -mom macro package now has full support for eqn, pic, and tbl, as well
   as captioning and labelling of pdf images and preprocessor output.  Lists
   of Figures, Equations, and Tables can now be autogenerated.  PDF_IMAGE has
   a new FRAME option.

o A French introduction to the -me macro package has been added (file
   `meintro_fr.me').

o In -mdoc, command %C is now available, providing a city or place
   reference.


VERSION 1.22.2
==============

Tbl
---

o The character `#' can now be used as an eqn delimiter within tables.


Eqn
---

o A GNU extension

     delim on

   has been added to reactivate delimiters which have been disabled with
   `delim off'.


VERSION 1.22.1
==============

(There was no release 1.22.)

Groff
-----

o A new option `-j' has been added to call the `chem' preprocessor.

Tbl
---

o Improved line numbering support.

Macro Packages
--------------

o Support for the `refer' preprocessor has been added to the -mm macro
   package.

o In -me, the `TH' macro was changed for compatibility with line number
   support in tables.

   `bl' now works inside of blocks.

   The behaviour of centered blocks has been improved.

   Line numbering support has been improved.

o The -mom macro package has reached version 2.0, focusing on PDF output
   with gropdf (using the new `pdfmom' wrapper script).  See the file
   `version-2.html' of the -mom documentation for a list of the many changes.

o Some generic Unicode fallback characters (mainly Roman numerals) have been
   added.

Gropdf
------

o A new driver for generating PDF output directly, contributed by Deri James
   <deri AT chuzzlewit DOT myzen DOT co DOT uk>.  Note that this driver is written in Perl,
   thus you need a working Perl installation to run this output device.

Pdfmom
------

o A new wrapper around groff that facilitates the production of PDF
   documents from files formatted with the -mom macros.


VERSION 1.21
============

Troff
-----

o The new `lsm' request specifies a macro to be invoked when leading spaces
   in an input line are encountered (which are removed then).  Number
   registers `lsn' and `lss' hold the number of removed leading spaces and
   the corresponding horizontal space, respectively.

o There is a new warning category `file', enabled by default.  The `mso'
   request emits warnings in this category when the requested macro file does
   not exist.

o The new `class' request assigns a short name to a set of characters
   which can be referred to in the `cflags' request.  This is especially
   useful to control line-breaking and hyphenation rules in CJK languages.

o Three new values for the `cflags' request have been added, which are
   needed for proper CJK support.

     128  prohibit before but allow break after character
     256  prohibit after but allow break before character
     512  allow break before and after character

Tbl
---

o A new global option `nowarn' suppresses warnings if tables are longer than
   the current line width.

Afmtodit
--------

o New option `-o' to specify the name of the output file.

Macro Packages
--------------

o A new macro `%U' has been added to the mdoc package to indicate a URL
   reference within an .Rs/.Re environment.

o Rudimentary support for the Japanese script has been added, most suitable
   for man page handling as output by grotty.  The file `ja.tmac' contains
   the necessary setup to allow line breaks before and after CJK characters
   (with proper exceptions).  Note, however, that no inter-character spacing
   is implemented yet -- this usually causes many warnings about bad line
   breaks.


VERSION 1.20.1
==============

A packaging error made it necessary to publish this release.  No
user-visible changes.


VERSION 1.20
============

Groff
-----

o XHTML support has been added to grohtml and can be specified by
   -Txhtml.  This option also utilizes the MathML capability of
   eqn and combines the outputs of both in the final XHTML file.
   Users can also specify the `-P-V' option together with `-Txhtml'
   in groff.  This has the effect of creating an XHTML validator
   button at the bottom of each page.

o Some options have been added to control a new preprocessor,
   `preconv' (see below): `-k' activates it, `-K' sets the input
   encoding, and `-D' sets the default encoding.

o A new environment variable `GROFF_ENCODING' sets the encoding
   of input files; it implies command option `-k'.

Troff
-----

o Two new requests `device' and `devicem' have been added which are
   equivalents to the \X and \Y escapes, respectively.

o A new read-only number register `.br' is available which is set to 1
   if a macro is called as .foo and to 0 if called as 'foo.  This allows to
   reliably modify requests.

     .als bp AT orig bp
     .de bp
     .  tm before bp
     .  ie \\n[.br] .bp AT orig
     .  el 'bp AT orig
     .  tm after bp
     ..

o A new request `fzoom' has been added to adjust the optical size of a
   font in relation to the others.  The zoom factor is given in integer
   multiples of 1/1000th.  In the following example, the CR font is
   magnified by 10% (the zoom factor is 1.1).

     .fam P
     .fzoom CR 1100
     .ps 12
     Palatino and \f[CR]Courier\f[]

   The new number register `.zoom' holds the zoom value of the current font,
   in multiples of 1/1000th.

o The `cflags' request has been extended with a new flag value 64, to be
   used in combination with values 2 (break before character) and 4 (break
   after character).  If set, the hyphenation codes of the surrounding
   characters are ignored.

o A new debugging request, `pev', has been added to print all of the current
   known environments to stderr.  It first prints the state of the current
   environment, then iterates through all of the known environments, printing
   each except the one that is current.

o A new escape `\$^' has been added.  It represents the parameters of a
   macro as if they were an argument to the `ds' request.  This is used by
   `trace.tmac'.

o A new read-only number register `.O' is available which returns the
   current suppression level as set by the `\O' escape.

o The space width emitted by the `\|' and `\^' escape sequences can be
   controlled on a per-font basis.  If there is a glyph named `\|' or `\^',
   respectively (note the leading backslash), defined in the current font
   file, use this glyph's width instead of the default value.

   This behaviour is not new, but hasn't been documented before.

Nroff
-----

o Two new command line options `-w' and `-W' are accepted and passed to
   groff to enable and disable warning messages, respectively.

Preconv
-------

o This is a new preprocessor to convert various input encodings to something
   groff understands (this is, ASCII and \[uXXXX] entities, with `XXXX' a
   hexadecimal number with 4 to 6 digits, representing a Unicode input code).
   Normally, preconv should be invoked with options `-k' and `-K' of groff.
   See the preconv man page for details.

Pic
---

o int(x) now really behaves as documented: It truncates the non-integer part
   of x, this is, it rounds towards zero and not towards the next integer
   less than or equal to x.

o Pic now supports up to 32 macro arguments (and up to 16 on EBCDIC
   platforms).

o Heinz-Jürgen Örtel contributed code for two new keywords, `xslanted' and
   `yslanted', which can change the shape of boxes into arbitrary
   parallelograms.

Tbl
---

o Latest versions of DWB tbl introduced an `x' column specifier for a single
   column expanded to the line width.  GNU tbl has now been extended to
   support even multiple `x' specifiers within a table.

o To avoid collision with the new `x' specifier, a block formatting macro
   must now be selected with specifier letter `m'.

Eqn
---

o Eric S. Raymond has added a new device type to eqn, MathML.  When
   -TMathML is enabled, eqn now emits MathML formula markup rather than
   groff commands.  The new groff -Txhtml device uses this.

Chem
----

o The preprocessor `chem' was added.  `chem' is a roff language to generate
   chemical structure diagrams.  It generates `pic' output.

Grops
-----

o The PS font definition files have been regenerated with newer AFM versions
   from Adobe's 35 core fonts as present in most Level 2 PS printers.  The
   changes are minor (most notably, the addition of the `Euro' glyph and an
   extended set of kerning values).

   For backwards compatibility, the old set of font definition files is still
   available; for details please read the man page of grops.

Grotty
------

o \D'p...' is now supported if the polygon consists entirely of horizontal
    and vertical lines.

Grohtml
-------

o XHTML support has been added.

o New command line option `-V' (to be used in XHTML mode) to produce an
   XHTML validator button.

o New command line option `-y' to produce a right-justified groff signature
   at the end of the document (in combination with option `-V').

Gxditview
---------

o Support for keyboard navigation has been improved.

o Similar to other X11 applications, there are now two resource files,
   `GXditview' and `GXditview-color'.

Groffer
-------

o `groffer' version 1.* exists now in a shell and a Perl version.

Afmtodit
--------

o New option `-c' to output more font information as comments.

o New option `-k' to suppress output of kerning data.

o New option `-f NAME' to set the internal name of the groff font.

Macro Packages
--------------

o Joachim Walsdorff contributed the `hdtbl' package for the generation of
   tables, using a syntax very similar to the HTML table model.  For
   example, a table with two cells and two rows looks like this:

     .TBL cols=2
     .  TR .TD 1*1 .TD 1*2
     .  TR .TD 2*1 .TD 2*2
     .ETB

   Here the same table using a more expanded syntax:

     .TBL cols=2
     .  TR
     .    TD 1*1
     .    TD 1*2
     .  TR
     .    TD 2*1
     .    TD 2*2
     .ETB

   Tables can be nested; `hdtbl' works without a preprocessor so that the
   full capability of groff's macro engine is available.

   This package currently works with `-Tps' only.

o -mandoc now supports multiple man pages (in either man or mdoc format).

o Fabrice Ménard contributed locales support.  In particular, it is now
   possible to get French localization of the main macro packages (-ms, -mm,
   -me, and -mom, but not -man and -mdoc which are localized differently) by
   appending `-mfr' to the list of macro packages.  Example:

     groff -ms -mfr foo > foo.ps

   Note that latin-9 input encoding is used for French (to support the `oe'
   ligature).

o Swedish macro localization (with `-msv') has been added.

o German macro localization (with `-mde' and `-mden' for traditional and
   new orthography, respectively) has been added.

o Czech macro localization (with `-mcs') has been added.

   Note that latin-2 input encoding is used for Czech.

o A new macro `Dx' has been added to the mdoc package which identifies the
   DragonFly OS.

o If mdoc is used to print multiple man pages (together with the -rcR=0
   command line option), each man page now starts a new page.

o -mtrace has been considerably improved, now showing number and string
   register assignments, among other things.  See the groff_trace man page
   for details.

o The PSPIC macro now works with all devices (producing a hollow
   rectangle on devices which don't support inclusion of PS images) and
   is loaded in troffrc at start-up.

o A new auxiliary macro package `62bit' has been added which provides some
   macros for adding, multiplying, and dividing signed 62bit integers (mainly
   to handle normal groff number operations without risking overflow errors).

o For -ms, Eric S. Raymond contributed support for ancient Bell Labs
   localisms `.SC', `.UC', `.P1', and `.P2'.  The latter three are enabled
   only after .SC is called.

o A new string, `SN-STYLE', has been added to the ms macros, controlling
   the formatting of section numbers in headings defined by `.NH'.

o The new macro package `ptx' provides a template definition for the `.xx'
   macro as needed by GNU ptx (for creating permuted indices).


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 keeps 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'
       produces 14pt headings, `.NH 2' produces 12pt, and all other
       levels 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.


VERSION 1.19.1
==============

Groff
-----

o The argument of the command line option `-I' is now also passed to troff
   and grops, specifying a directory to search for files on the command line,
   files named in `so' and `psbb' requests, and files named in \X'ps: file'
   and \X'ps: import' escapes.

o If option `-V' is used more than once, the commands are both printed
   on standard error and run.

Troff
-----

o Two new read-only, string-valued registers `.m' and `.M' return the
   name of the current drawing and background color, respectively.

o New read-only register `.U' which is set to 1 if in safer mode and set
   to 0 if in unsafe mode.

o An input encoding file for latin-5 (a.k.a. ISO 8859-9) has been added.
   Example use:

     groff -Tdvi -mlatin5 my_file > my_file.dvi

   Note that some output devices don't support all glyphs of this encoding.

o If the `return' request is called with an argument, it exits twice,
   namely the current macro and the macro one level higher.  This is
   used to define a wrapper macro for `return' in trace.tmac.

o For completeness, two new requests have been added: `dei1' and `ami1'.
   They are equivalent to `dei' and `ami', respectively, but the macros
   are executed with compatibility mode off (similar to `de1' and `am1').

o New command line option `-I' to specify a directory for files (both
   those on the command line and those named in `psbb' requests).  This is
   also handled by the groff wrapper program.

o Since version 1.19 you can say `.vs 0'.  Older versions emit a warning
   and convert this to `.vs \n[.V]'.

   This hasn't been documented properly.  Note that `.vs 0' isn't saved in a
   diversion since it doesn't result in vertical motion.

Pic
---

o Dashed and dotted ellipses have been implemented.

Tbl
---

o New specifier `x' to make tbl call a user-defined macro on a table
   cell.  Patch by Heinz-Jürgen Oertel <hj DOT oertel AT surfeu DOT de>.

Grap2graph
----------

o A new script contributed by Eric S. Raymond <esr AT thyrsus DOT com>.  It
   converts a grap diagram into a cropped image.  Since it uses gs and the
   PNM library, virtually all graphics formats are available for output.
   [Note that the grap program itself isn't part of the groff package;
   see the file MORE.STUFF how to obtain grap.]

Grohtml
-------

o New option `-j' to emit output split into multiple files.

Grops
-----

o New command line option `-I' to specify a directory to search for files
   on the command line and files named in \X'ps: import' and \X'ps: file'
   escapes.  This is also handled by the groff wrapper program.

o The default value for the `broken' keyword in the DESC file is now 0.

Grolj4
------

o A new man page `lj4_font(5)' documents how fonts are accessed with
   grolj4.

o The built-in fonts for LJ4 and newer PCL 5 devices have been completely
   revised, mainly to access as much glyphs as possible.  The provided
   metric files should be compatible with recent PCL 5 printers also.
   Additionally, font description files have been added for the Arial and
   Times New Roman family, the MS symbol, and Wingdings fonts.

Afmtodit
--------

o New option `-x' to prevent use of built-in Adobe Glyph List.

Hpftodit
--------

o Completely revised to handle HP TrueType metric files also.  See the
   hpftodit manual page for more details.

Groffer
-------

o This version is a rewrite of groffer in many parts, but it is kept in
   the old single script style.

   New options: --text, --mode text, --tty-viewer, --X, --mode X,
   --X-viewer, --html, --mode html, --html-view, --apropos-data,
   --apropos-devel, --apropos-progs.

   New documentation file: README_SH.

   Enhancement of the configuration files and the `apropos' handling.

Macro Packages
--------------

o www.tmac: New macro `JOBNAME' to split output into multiple files.

o In mdoc, multiple calls to `.Lb' are now supported in the LIBRARY
   section.


VERSION 1.19
============

Troff
-----

o Input encoding files for latin-9 (a.k.a. latin-0 and ISO 8859-15) and
   latin-2 (ISO 8859-2) have been added.  Example use:

     groff -Tdvi -mlatin9 my_file > my_file.dvi

   You still need proper fonts with the necessary glyphs.  Out of the box,
   the groff package supports latin-9 only for -Tps, -Tdvi, and -Tutf8,
   and latin-2 only for -Tdvi and -Tutf8.

o Composite glyphs are now supported.  To do this, a subset of the Adobe
   Glyph List (AGL) Algorithm as described in

     http://partners.adobe.com/public/developer/opentype/index_glyph.html

   is used to construct glyph names based on Unicode character codes.  The
   existing groff glyph names are frozen; no glyph names which can't be
   constructed algorithmically will be added in the future.

   The \[...] escape sequence has been extended to specify multiple glyph
   components.  Example:

     \[A ho]

   this accesses a glyph with the name `u0041_0328'.

   Some groff glyphs which are useful as composites map to `wrong' Unicode
   code points.  For example, `ho' maps to U+02DB which is a spacing
   ogonek, whereas a non-spacing ogonek U+0328 is needed for composite
   glyphs.  The new request

     .composite from to

   changes the mapping while a composite glyph name is constructed.
   To make \[A ho] yield the expected result,

     .composite ho u0328

   is needed.  [The new file `composite.tmac' loaded at start-up already
   contains proper calls to `.composite'.]

   Please refer to the info pages of groff and to the groff_char man page
   for more details.

o A new request `fschar' has been added to define font-specific fallback
   characters.  They are searched after the list of fonts declared with the
   `fspecial' request but before the list of fonts declared with `special'.

o Fallback characters defined with `fschar' can be removed with the
   new `rfschar' request.

o A new request `schar' has been added to define global fallback
   characters.  They are searched after the list of fonts declared with the
   `special' request but before the already mounted special fonts.

o In groff versions 1.18 and 1.18.1, \D'f ...' didn't move the current
   point horizontally.  Despite of being silly, this change has been
   reverted for backwards compatibility.  Consequently, the intermediate
   output command `Df' also moves the position horizontally again.

   \D'f ...' is deprecated since it depends on the horizontal resolution of
   the output device (given with the `hor' parameter in the DESC file).
   Use the new \D'Fg ...' escape instead.

o For orthogonality, new \D subcommands to change the fill color are
   available:

     \D'Fr ...' (rgb)
     \D'Fc ...' (cmy)
     \D'Fg ...' (gray)
     \D'Fk ...' (cmyk)
     \D'Fd'     (default color)

   The arguments are the same as with the `defcolor' request.  The current
   position is *not* changed.

o The values set with \H and \S are now available in number registers
   \n[.height] and \n[.slant], respectively.

o The `.pe' number register isn't new but hasn't been documented before.
   It is set to 1 during a page ejection caused by the `bp' request.

o The new glyph symbol `tno' is a textual variant of `no'.

o The new glyph symbol `+e' represents U+03F5, GREEK LUNATE EPSILON SYMBOL.
   (Well, it is not really new since it has been previously supported by
   grolj4.)  The mapping for both the dvi and lj4 symbol font has been
   changed accordingly so that Greek small letter epsilon, `*e', has the
   same glyph shape as with other devices.

Grops
-----

o The font `freeeuro.pfa' has been added to provide various default glyph
   shapes for `eu' and `Eu'.

o It is now possible to access all glyphs in a Type 1 font, not only 256
   (provided the font file created by afmtodit has proper entries).  grops
   constructs additional encoding vectors on the fly if necessary.

o The paper size is now emitted via the %%DocumentMedia and PageSize
   mechanisms so that it is no longer required to tell `gv' or `ps2pdf'
   about the paper size.  The `broken' flag value 16 omits this feature
   (the used PostScript command `setpagedevice' is a LanguageLevel 2
   extension) -- if you intend to further process grops output to get an
   encapsulated PS (EPS) file you must also use this option.

   Patch by Egil Kvaleberg <egil AT kvaleberg DOT no>.

o Non-slanted PostScript metrics have been changed again; they no longer
   contain negative left italic correction values.  This assures correct
   spacing with eqn.

Grodvi
------

o The font cmtex10 has been added as the special font `SC' to the DVI fonts.
   It is used as a font-specific special font for CW and CWI.

o New options -l and -p to set landscape orientation and the paper size.
   grodvi now emits a `papersize' special which is understood by DVI drivers
   like dvips.

   Consequently, the DESC file should contain a `papersize' keyword.

o The glyph shapes for \[*f] and \[*e] have been exchanged with \[+f] and
   \[+e], respectively, to be in sync with all other devices.

o Glyphs \[HE] and \[DI] have been replaced with \[u2662] and \[u2661],
   respectively, since the former two glyphs have a black (filled) shape
   which grodvi doesn't provide by default (it never has actually).

Grolj4
------

o The glyphs \[*e] and \[+e] have been exchanged to be in sync with
   all other devices.

o The glyph \[~=] is now called \[|=].  Similar to other devices, \[~=]
   is now another name for glyph \[~~].

Grotty
------

o New option `-r'.  It is similar to the -i option except it tells grotty to
   use the `reverse video' attribute to render italic fonts.

Pic
---

o New command `figname' to set the name of a picture's output box in TeX
   mode.

Refer
-----

o The environment variable `REFER' to override the name of the default
   database isn't new but hasn't been documented before.

Soelim
------

o New option `-r' to avoid emission of `.lf' lines.

o New option `-t' to emit TeX comment lines (giving current file and the
   line number) instead of `.lf' lines.

Afmtodit
--------

o Unencoded glyphs in an AFM file are output also (since grops can now emit
   multiple encoding vectors for a single font).

o New option `-m' to prevent negative left italic correction values.

o The mapping and encoding file together with file `DESC' are now searched
   in the default font directory also.  Please refer to the man page of
   afmtodit for more details.

Macro Packages
--------------

o Larry Kollar <kollar AT alltel DOT net> and others made the man macros more
   customizable.

   . New command line options -rFT, -rIN, and -rSN to set the vertical
     location of the footer line, the body text indentation, and the
     sub-subheading indentation.

   . New command line option -rHY (similar to the ms macros) to control
     hyphenation.

   . New macros `.PT' and `.BT' to print the header and footer strings.
     They can be replaced with a customized version in `man.local'.

   . The string `HF' now holds the typeface to print headings and
     subheadings.

   . Similar to the ms macros, the LT register now defaults to LL if not
     explicitly specified on the command line.

o troff's start-up file `troffrc' now includes `papersize.tmac' to set
   the paper size with the command line option `-dpaper=<size>'.

   Possible values for `<size>' are the same as the predefined `papersize'
   values in the DESC file (only lowercase; see the groff_font man page)
   except a7-d7.  An appended `l' (ell) character denotes landscape
   orientation.  Examples: `a4', `c3l', `letterl'.

   Most output drivers need additional command line switches `-p' and
   `-l' to override the default paper length and orientation as set in
   the driver specific DESC file.

   For example, use the following for PS output on A4 paper in landscape
   orientation:

     groff -Tps -dpaper=a4l -P-pa4 -P-l -ms foo.ms > foo.ps


VERSION 1.18.1
==============

Troff
-----

o The non-slanted PostScript font definition files have been regenerated to
   include left and right italic correction values.  Applying those to a
   glyph (this is, prepending the glyph with `\,' and appending `\/' to the
   glyph) sets the glyph width to the real value given by the horizontal
   bounding box values.  Without those escapes, the advance width for the
   particular glyph is used (which can differ considerably).

   Most users will neither need this feature nor notice a difference in
   existing documents (provided \, and \/ is used as advertised, namely for
   italic fonts only); its main goal is to improve image generation with
   grohtml.

   This is an experimental change, and feedback is welcome.

Tbl
---

o Added global option `nospaces' to ignore leading and trailing spaces in
   data items.

Grolbp
------

o The option -w (--linewidth) has been added (similar to other device
   drivers) to set the default line width.

Grn
---

o Support for b-spline and Bezier curves has been added.

Groffer
-------

o New option `--shell' to select the shell under which groffer shall run.

Macro Packages
--------------

o The string `Am' (producing an ampersand) has been added to mdoc for
   compatibility with NetBSD.

o `.IX' is now deprecated for mom; you should use `.IQ' (Indent Quit)
   instead.

o In mom, new inlines `FWD', `BCK', `UP', and `DOWN' deal with horizontal
   and vertical movements; please refer to contrib/mom/NEWS for more
   details.

o New macro ENDNOTES_HDRFTR_CENTER for mom to better control headers.

Miscellaneous
-------------

o The `papersize' keyword in the DESC file now accepts multiple arguments.
   It is scanned from left to the right, and the first valid argument is
   used. This makes it possible to provide a fallback paper size.

   Example:

     papersize /etc/papersize a4

o A local font directory has been prepended to the default font path; it
   defaults to /usr/local/share/groff/site-font.  Similar to the normal
   font searching process, files must be placed into a devXXX subdirectory,
   e.g.

     /usr/local/share/groff/site-font/devps/FOO

   for a PostScript font definition file FOO.

***************************************************************************

Troff
-----

o Color support has been added to troff and pic (and to the device drivers
   grops, grodvi, grotty, and grohtml -- other preprocessors and drivers will
   follow).  A new function `defcolor' defines colors; the escape sequence
   `\m' sets the drawing color, the escape sequence `\M' specifies the
   background color for closed objects created with \D'...' commands.
   `\m[]' and `\M[]' switch back to the previous color.  `\m' and `\M'
   correspond to the new troff output command sets starting with `m' and
   `DF'.  The device-specific default color is called `default' and can't be
   redefined.

   Use the `color' request to toggle the usage of colors (default is on); the
   read-only register `.color' is 0 if colors are not active, and non-zero
   otherwise.

   The old `Df' output command is mapped onto `DFg'; all color output
   commands don't change the current font position (consequently, `Df'
   doesn't either).

   Outputting color can be disabled in troff and groff with the option -c
   (it is always disabled in compatibility mode).  See the section on grotty
   for the GROFF_NO_SGR environment variable also.

   For defining color components as fractions between 0 and 1, a new scaling
   indicator `f' has been introduced: 1f = 65536u.  For testing whether a
   color is defined (with .if and .ie), a new conditional operator `m' is
   available.

   More details can be found in the groff_diff.7 manual page and in
   groff.texinfo.

o Similar to \m and \M, \f[] switches back to the previous font.  \fP
   (and \f[P]) is still valid for backwards compatibility.

o The new escape \F is the same as `.fam'; \F[] switches back to previous
   family -- \F[P] selects family `P'.

o Two new glyph symbols are available: `eu' is the official Euro symbol;
   `Eu' is a font-specific glyph variant.

o The new glyph symbols `t+-', `tdi', and `tmu' are textual variants of
   `+-', `di', and `mu', respectively.

o Latin-1 character 181 (PS name `mu', Unicode name U+00B5 MICRO SIGN) has
   got the troff glyph name `mc'.

o -Tutf8 is now available on EBCDIC hosts.

o Strings can take arguments, using this syntax: \*[foo arg1 arg2 ...].
   Example:

     .ds xxx This is a \\$1 test.
     \*[xxx nice]

o It is now possible to have whitespace between the first and second dot (or
   the name of the ending macro) to end a macro definition.  Example:

     .de !
     ..
     .
     .de foo
     .  nop Hello, I'm `foo'.
     .  nop I will now define `bar'.
     .  de bar !
     .    nop Hello, I'm `bar'.
     .  !
     ..

o `.fn' is a new string-valued register which returns the (internal) real
   font name; styles and families are properly concatenated.

o Three new read/write registers `seconds', `minutes', and `hours' contain
   the current time, set at start-up of troff.  Use the `af' request to
   control their output format.

o The new request `fchar' can be used to provide fallback characters.  It
   has the same syntax as the `char' request; the only difference is that a
   character defined with `.char' hides the glyph with the same name in the
   current font, whereas a character defined with `.fchar' is checked only if
   the particular glyph isn't found in the current font.  This test happens
   before checking special fonts.

o In analogy to the `tmc' request, `.writec' is the same as `.write' but
   doesn't emit a final newline.

o The new request `itc' is a variant of `.it' for which a line interrupted
   with \c counts as one input line.

o Two new requests `ds1' and `as1' which are similar to `ds' and `as' but
   with compatibility mode disabled during expansion of strings defined by
   them.

o The syntax of the `substring' request has been changed: The first
   character in a string now has index 0, the last character has index -1.
   Note that this is an incompatible change.

o To emit strings directly to the intermediate output, a new `output'
   request has been added; it is similar to `\!' used at the top level.

o `.hpf' has been extended.  It can now handle most TeX hyphenation
   pattern files without modification.  To do that, the commands \patterns,
   \hyphenation, and \endinput are recognized.  Please refer to groff_diff.7
   for more information.

o `hpfcode' is a new request to provide an input encoding mapping for the
   `hpf' request.

o The new request `hpfa' appends hyphenation patterns (`hpf' replaces
   already existing patterns).

o A new request `ami' (append macro indirect) has been added.  The first and
   second parameter of `ami' are taken from string registers rather than
   directly; this very special request is needed to make `trace.tmac'
   independent from the escape character (which might even be disabled).

o The new request `sizes' is similar to the `sizes' command in DESC files.
   It expects the same syntax; the data must be on a single line, and the
   final `0' can be omitted.

o `trin' (translate input) is a new request which is similar to `tr' with
   the exception that the `asciify' request uses the character code (if
   any) before the character translation.  Example:

     .trin ax
     .di xxx
     a
     .br
     .di
     .xxx
     .trin aa
     .asciify xxx
     .xxx

   The result is `x a'.  Using `tr', the result would be `x x'.

o The request `pvs' isn't new, but hasn't been documented before.  It
   adds vertical space after a line has been output.  This makes it an
   alternative to the `ls' request to produce double-spaced documents.
   The read-only register `.pvs' holds the current amount of the
   post-vertical line space.

o For compatibility with plan 9's troff, multiple `pi' requests are
   supported:

     .pi foo
     .pi bar

   is now equivalent to

     .pi foo | bar

o A new escape sequence `\O' is available to disable and enable glyph
   output.  Please see groff_diff.7 and groff.texinfo for more details.

o The escapes `\%', `\&', `\)', and `\:' no longer cause an error in \X;
   they are ignored now.  Additionally `\ ' and `\~' are converted to
   single space characters.

o The default tab distance in nroff mode is now 0.8i to be compatible
   with UNIX troff.

o Using the latin-1 input character 0xAD (soft hyphen) for the `shc'
   request was a bad idea.  Instead, it is now translated to `\%', and
   the default hyphenation character is again \[hy].  Note that the glyph
   \[shc] is not useful for typographic purposes; it only exists to have
   glyph names for all latin-1 characters.

Macro Packages
--------------

o Peter Schaffter <df191 AT ncf DOT ca> has contributed a new major macro package
   called `mom', mainly for non-scientific writers, which takes care of
   many typographic issues.  It comes with a complete reference (in HTML
   format) and some examples.  `mom' has been designed to format documents
   for PostScript output only.

o Two macros `AT' (AT&T) and `UC' (Univ. of California) have been added to
   the man macros for compatibility with older BSD releases.

o Both the man and mdoc macro packages now use the LL and LT registers for
   setting the line and title length, respectively (similar to those
   registers in the ms macro package).  If not set on the command line or
   in a macro file loaded before the macro package itself, they default to
   78n in nroff mode and 6.5i in troff mode.

o The `-xwidth' specifier in the mdoc macro package has been removed.  Its
   functionality is now integrated directly into `-width'.  Similarly,
   `-column' has been extended to provide this functionality also.

o A new macro `Ex' has been added to the mdoc macro package to document an
   exit status.

o The PSPIC macro has been extended to work with DVI output (`pspic.tmac' is
   now automatically loaded for -Tdvi), using a dvips special to load the EPS
   file.

o The trace.tmac package now traces calls to `am' also.  Additionally, it
   works in compatibility mode.

o `troff.1' has been split.  Differences to UNIX troff are now documented
   in the new man page `groff_diff.7'.

o `groff_mwww.7' has been renamed to `groff_www.7'.  The file mwww.tmac
   has been removed.

o `groff_ms.7' has been completely rewritten.  It now contains a complete
   reference to the ms macros.

o `groff_trace.7' documents the trace macro package.

o Changes in www.tmac:

     Note that HTML support is still in alpha change, so it is rather likely
     that both macro names and macro syntax will change.  Some of the macros
     mentioned below aren't really new but haven't been documented properly
     before.

     The following macros have been renamed:

         MAILTO     -> MTO
         IMAGE      -> IMG
         LINE       -> HR

     For consistency, the macros `URL', `FTL', and `MTO' now all have the
     address as the first parameter followed by the description.

     By default, grohtml generates links to all section headings at the top
     of the document.  Use the new `LK' macro to specify a different place.

     For specifying the background color and a background image, use the
     new macros `BCL' and `BGIMG', respectively.

     The macro `NHR' has been added; it suppresses the generation of top and
     bottom rules which grohtml emits by default.

     The new macro `HX' determines the cut-off point for automatic link
     generation to headings.

     The image position parameter names in `IMG' have been changed to `-L',
     `-R', and `-C'.

     New macro `PIMG' for inclusion of a PNG image (it automatically
     converts it into an EPS file if not -Thtml is used).

     New macro `MPIMG' for putting a PNG image into the left or right margin
     (it automatically converts it into an EPS file if not -Thtml is used).

     New macros `HnS', `HnE' to start and end a header line block.

     New macro `DC' to produce dropcap characters.

     New macro `HTL' to generate an HTML title line only but no H1 heading.

     New macros `ULS' and `ULE' to start and end an unordered list.  The new
     macro `LI' inserts a list item.

Groff
-----

o The new command line option `-c' disables color output (which is always
   disabled in compatibility mode).

Nroff
-----

o Two new command line options `-c' and `-C'; the former passes `-c' to
   grotty (switching to the old output scheme); the latter passes `-C' to
   groff (enabling compatibility mode).

Pic
---

o New keywords `color' (or `colour', `colored', `coloured'), `outline' (or
   `outlined'), and `shaded' are available.  `outline' sets the color of the
   outline, `shaded' the fill color, and `color' sets both.  Example:

     circle shaded "green" outline "black" ;

   Filled arrows always use the outline color for filling.

   Color support for TeX output is not implemented yet.

Pic2graph
---------

o A new script contributed by Eric S. Raymond <esr AT thyrsus DOT com>.  It
   converts a PIC diagram into a cropped image.  Since it uses gs and the PNM
   library, virtually all graphics formats are available for output.

Eqn2graph
---------

o A new script contributed by Eric S. Raymond <esr AT thyrsus DOT com>.  It
   converts an EQN diagram into a cropped image.  Since it uses gs and the PNM
   library, virtually all graphics formats are available for output.

Groffer
-------

o A new script contributed by Bernd Warken <bwarken AT mayn DOT de>.  It displays
   groff files and man pages on X and tty, taking care of most parameters
   automatically.

Grog
----

o Documents using the mom macro package are recognized.

Grops
-----

o Color support has been added.

o A new option `-p' is available to select the output paper size.  It has
   the same syntax as the new `papersize' keyword in the DESC file.

Grodvi
------

o By default, font sizes are now available in the range 5-10000pt, similar
   to PS fonts. If you want the old behaviour (i.e., font sizes at discrete
   values only), insert the following at the start of your document:

     .if '\*[.T]'dvi' \
     .  sizes 500 600 700 800 900 1000 1095 1200 1400 1440 1600 \
              1728 1800 2000 2074 2200 2400 2488 2800 3600

o A new font file HBI (using cmssbxo10; this is slanted sans serif bold
   extended) has been added.

o Two font families are now available: `T' and `H'.

o EC and TC fonts have been integrated.  Use `-mec' (calling the file
   ec.tmac) to switch to them.  Those fonts give a much better coverage of
   the symbols defined by groff than the CM fonts.

   Note that ec.tmac must be called before any language-specific files; it
   doesn't take care of hcode values.

o Color support has been added.  For drawing commands, colors are translated
   to gray values currently.

Grotty
------

o Color support has been added, using the SGR (ISO 6429, sometimes called
   ANSI color) escape sequences.

o SGR escape sequences are now used by default for underlining and bold
   printing also, no longer using the backspace character trick.  To revert
   to the old behaviour, use the `-c' switch.

   Note that you have to use the `-R' option of `less' to make SGR escapes
   display correctly.  On the other hand, terminal programs and consoles like
   `xterm' which support SGR sequences natively can directly display the
   output of grotty.  Consequently, the options `-b', `-B', `-u', and `-U'
   work only in combination with `-c' and are ignored silently otherwise.

   For the `man' program, it may be necessary to add the `-R' option of
   `less' to the $PAGER environment variable (or $MANPAGER, depending on the
   used `man' program); alternatively, you can use `man's `-P' option (or
   adapt its configuration file accordingly).  See man(1) for more details.

o If the environment variable GROFF_NO_SGR is set, SGR output is disabled,
   reverting to the old behaviour.

o A new special \X'tty: sgr n' has been added; if n is non-zero or missing,
   enable SGR output (the default).

o If the new option `-i' is used (only in SGR mode), grotty sends escape
   sequences to set the italic font attribute instead of the underline
   attribute for italic fonts.  Note that many terminals don't have support
   for this (including xterm).

Grohtml
-------

o Color support for glyphs has been added.

o New option `-h' to select the style of headings in HTML output.

o New option `-b' to set the background colour to white.

o New options `-a' and `-g' to control the number of bits for anti-aliasing
   used for text and graphics, respectively.  Default value is 4; 0 means
   no anti-aliasing.

o groff character/glyph entities now map onto HTML 4 character entities.

Grolbp
------

o Valid paper sizes are now specified as with the new `papersize' keyword
   in the DESC file.  Specifically, the old custom paper type format
   `custAAAxBBB' is no longer supported.

Miscellaneous
-------------

o A new manual page `ditroff.7' is available.

o The groff texinfo manual is installed now, together with a bunch
   of examples.

o A new keyword `papersize' has been added to the DESC file format.  Its
   argument is either

   . a predefined paper format (e.g. `A4' or `letter')

   . a file name pointing to a file which must contain a paper size
     specification in its first line (e.g. `/etc/papersize')

   . a custom paper size definition like `35c,4i'

   See groff_font(5) for more details.  This keyword only affects the
   physical dimensions of the output medium; grops, grolj4, and grolbp use it
   currently.  troff completely ignores it.


VERSION 1.17.2
==============

This is major bug-fixing release which should replace 1.17.1.

Troff
-----

o The `IMAGE' macro in www.tmac has changed: Now the optional 2nd parameter
   gives the horizontal image location (left, centered, or right), and the
   optional 3rd and 4th parameter the image dimensions.


VERSION 1.17.1
==============

This is mainly a bug-fixing release.

Troff
-----

o Two new requests `de1' and `am1' which are similar to `de' and `am' but
   with compatibility mode disabled during expansion of macros defined by
   them.

o Added request `brp'.  This is the same as `\p'.

o Similar to other versions of troff, the `ns' request now works in all
   diversions, not only in the top-level one.

o New read-only number register `.ns'.  Returns 1 if in no-space mode,
   0 otherwise.

Nroff
-----

o Options -p (pic) and -t (tbl) added.

o The environment variable GROFF_BIN_PATH is now checked before PATH for
   finding groff.

Grohtml
-------

o New option `-D dir' to specify a directory in which all images are placed.

o New option `-I stem' to specify an image name stame.  If not given,
   `grohtml-XXX' is used (`XXX' is the process ID).


VERSION 1.17
============

Groff
-----

o `-mFOO' now searches first for `FOO.tmac' and then for `tmac.FOO'.  The
   old behaviour has been changed to overcome problems with platforms which
   have an 8+3 file name limit, and platforms which have other versions of
   troff installed also.  Additionally, all macro files have been renamed
   using the latter scheme to avoid 8+3 name clashes.

o The new environment variable GROFF_BIN_PATH is checked for programs groff
   is calling (preprocessors, troff, and output devices) before PATH.  If not
   set, it defaults to the directory where the groff binary is located.
   Previously, it was PATH only.  The nroff script only uses GROFF_BIN_PATH
   to find the groff binary but passes both the GROFF_BIN_PATH and PATH
   environment variables to groff.

Troff
-----

o The mdoc package has been completely rewritten, using the full power of
   GNU troff to remove limitations of Unix troff (which is no longer
   supported).  Most important changes are:

   . No argument limit
   . Almost all macros are parsed and callable (if it makes sense)
   . `.Lb': prints library names
   . `.Nm <punctuation>' now works as expected; `.Nm "" <punctuation>' has
     been withdrawn
   . Updated `.St' command
   . `.Fx': prints FreeBSD
   . `.Ox': prints OpenBSD
   . `.Bsx': prints BSD/OS
   . `.Brq', `.Bro', `.Brc': brace enclosure macros
   . `.Bd -centered': center lines
   . `.Bl -xwidth <string>': interpret <string> and use the resulting width
   . Support for double-sided printing (-rD1 command line switch)
   . Support for 11pt and 12pt document sizes (-rS11, -rS12 command line
     switches)

   `groff_mdoc.7' replaces `groff_mdoc.samples.7'; it now completely
   documents the mdoc package.

   Great care has been taken to assure backwards compatibility.  If you
   encounter any abnormal results, please report them to bug-groff AT gnu DOT org.

o A new command line option for the `man' macros (similar to the `mdoc'
   package) has been implemented: `-rcR=1' (now the default in nroff mode)
   produces one single, very long page instead of multiple pages.  `-rcR=0'
   deactivates it.

o The `return' request has been added to return immediately from a macro.

o A new request `nop' (no operation) has been added which is similar to
   `if 1'.  For example,

     .if t \{\
     Hallo!
     .\}

   can now be written as

     .if t \{\
     .  nop Hallo!
     .\}

o `box' and `boxa' are two new requests which behave similarly to `di' and
   `da' but don't include a partially filled line (which is restored after
   ending the diversion).

o The `asciify' request has been extended to `unformat' space characters
   and some other escape sequences also.

   `\ ' is no longer unformatted as a space but remains an unpaddable,
   unbreakable space character.

o The new `unformat' request is similar to `asciify' but only handles space
   characters and tabs specially if the diversion is reread, retaining font
   information.  This makes it possible to reformat diversions; for example
   the following

     .ll 3i
     .
     a01 a02 a03 a04 a05 a06 a07 a08 a09 a10.
     .
     .box box1
     .ev 1
     .nf
     \f[B]b01 b02 b03 b04 b05 b06 b07 b08 b09 b10.\f[P]
     .br
     .ev
     .box
     .
     c01 c02 c03 c04 c05 c06 c07 c08 c09 c10.
     .
     .unformat box1
     .box1

   gives

     a01  a02  a03  a04 a05 a06 a07
     a08 a09 a10.  c01 c02 c03  c04
     c05  c06 c07 c08 c09 c10.  b01
     b02 b03 b04 b05  b06  b07  b08
     b09 b10.

   Without the `unformat' request, space characters are converted to word
   space nodes which are no longer stretchable, and the result would be

     a01  a02  a03  a04 a05 a06 a07
     a08 a09 a10.  c01 c02 c03  c04
     c05  c06 c07 c08 c09 c10.  b01
     b02 b03 b04 b05 b06 b07 b08
     b09 b10.

o The new request `linetabs' controls the `line-tabs' mode.  In line-tabs
   mode, tab distances are computed relative to the (current) output line.
   Otherwise they are taken relative to the input line.  For example, the
   following

     .ds x a\t\c
     .ds y b\t\c
     .ds z c
     .ta 1i 3i
     \*x
     \*y
     \*z

   yields

     a         b         c

   In line-tabs mode, the same code gives

     a         b                   c

   The new read-only number register `.linetabs' returns 1 if in line-tabs
   mode, and 0 otherwise.

o Two new requests `tm1' and `tmc' have been added to improve writing
   messages to the terminal.  `tm1' is similar to `tm' but allows leading
   whitespace.  `tmc' is similar to `tm1' but doesn't emit a final newline.

o For compatibility with sqtroff, the request `output' has been added.
   The behaviour is similar to `\!' at the top-level, that is, it directly
   inserts its argument into the intermediate output format.  The syntax
   is similar to .tm1, allowing leading whitespace.

o The new `spreadwarn' request makes troff warn if spaces in an output
   line are widened by a given limit or more.

o Use `warnscale' to change the scaling indicator troff uses for
   warning messages.

o A new request `dei' (define indirect) has been added.  The first and
   second parameter of `dei' are taken from string registers rather than
   directly; this very special request is needed to make `trace.tmac'
   independent from the escape character (which might even be disabled).

o It is now possible to save and restore the escape character with two new
   requests `ecs' and `ecr'.

o The new escape sequence \B'...' is an analogon to `\A': If the string
   within the delimiters is a valid numeric expression, return character `1',
   and `0' otherwise.

o The new escape sequence `\:' inserts a zero-width break point.  This is
   similar to `\%' but without a soft hyphen character.

o The `tr' request can now map characters onto `\~'.

o Calling the `fam' request without an argument switches back to the
   previous font family.

o The new read-only register `.int' is set to a positive value if the last
   output line is interrupted (i.e., if the input line contains `\c').

o The `writem' request is not new, but hasn't been documented before.  This
   is similar to `write' but instead of a string the contents of a given
   macro or string is written to a stream.

o The read/write number register `hp' to get/set the current horizontal
   position relative to the input line isn't new but hasn't been documented
   properly before.

o `\X' and `\Y' are now transparent for end-of-sentence recognition.

o The `cu' request in nroff mode now works as documented (i.e., it
   underlines spaces also).

Grog
----

o The grog script now works in non-compatibility mode also (which is the
   default).  As usual, use the `-C' option to activate compatibility mode.

Grops
-----

o A new option `-P' resp. a new environment variable `GROPS_PROLOGUE' has
   been added to select a different prologue file.

o The effect of the former `-mpsnew' option to access more Type 1 characters
   is now the default and no longer available.  To get the old behaviour
   (i.e., emulation of some glyphs by composition) use `-mpsold'.

Miscellaneous
-------------

o For security reasons the following changes have been done:

   . The tmac.safer file has been replaced with a built-in solution; .open,
     .opena, .pso, .sy, and .pi are completely disabled in safer mode (which
     is the default); to enable these requests the `-U' command line flag
     must be used.

   . Files specified with the .mso request or given with the `-m' command
     line option, and hyphenation patterns loaded with `.hpf' are no longer
     searched in the current directory by default (besides the usual tmac
     path).  Instead, the home directory is used.  To add the current
     directory, either use the `-U' or `-M' command line option or set the
     GROFF_TMAC_PATH environment variable to an appropriate value.

   . troffrc, troffrc-end, and eqnrc are neither searched in the current nor
     in the home directory (even if -U is given).  Use -M or GROFF_TMAC_PATH
     to change that.

   . Similarly, the current directory is no longer part of the font path.
     Use the `-F' command line option or the GROFF_FONT_PATH environment
     variable if you really need the current directory.

o groff now installs its data files into /usr/local/share/groff/<version> by
   default, following the GNU standard.  Additionally, a local tmac directory
   (by default /usr/local/share/groff/site-tmac) is scanned before the
   standard tmac directory.  Wrapper files for system-specific macro packages
   (if necessary) are put into /usr/local/lib/groff/site-tmac; this directory
   is searched before the local tmac directory.

o All programs now have option `-v' to show the version number; they exit
   immediately afterwards, following the GNU standards.  Additionally,
   `--version' and `--help' have been added, doing the obvious actions.
