in repository groff.
commit 14595d8c97a4fb95c1be098b9bbfd866d07de1e9
Author: G. Branden Robinson <address@hidden>
AuthorDate: Sun Apr 26 16:57:31 2020 +1000
NEWS: Make format regular.
Update fill column to 72 (for consistency with most other files in the
source tree) and reflow paragraphs accordingly.
Use two blank lines before version "sections" and only one before subsystem
"subsections". This is in fact the convention in older parts of the file,
but it got lost relatively recently.
Update editor assistance comments.

-o The new option -P takes an argument to pass to the device postprocessor

- italic (oblique) characters instead of underlining; note that it is up to
- your terminal (emulator) to support italics (xterm does since patch #314

- "-h"; the latter pair may eventually be deprecated and repurposed.
-
-o The new option -V emits the constructed groff command that nroff would run
- to standard output instead of executing it. Note that arguments to nroff
- that contain shell metacharacters may not be sufficiently escaped for the
- output of nroff -V to be cut and pasted to the shell prompt; this is a

Macro Packages
--------------
o The an (man) macro package supports new CS and CT number registers to
- control rendering of man page section headings and titles, respectively,
- in full capitals. These default off (with no visible effect on pages
- which already fully capitalize these strings in man page sources). The
- rationale is to encourage man page authors to preserve case distinction
- information in (or restore it to) their titles and section headings, while
- giving users (including system administrators, distributors, integrators,
- and maintainers of man(1) implementations) a way to view the rendered page
- elements in full capitals if desired.
-
-o The ms macro package no longer manipulates the warning level. If you want
- all warnings on, use the ".warn" request with no arguments in your ms
- document or pass "-w w" to groff (see troff(1) or the Texinfo manual for
- more on warnings).

-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.

commands don't change the current font position (consequently, `Df'
doesn't either).
