Changes in version 1.13.3, released on March 13, 2015
--- MAJOR NEW FEATURES ---
* When a manual is missing from an outdated database, let man(1)
show it anyway, using a KISS file system lookup as a fallback.
* Use this to always provide man(1), even without database support.
* Fatal errors no longer exist. If a file can be opened, mandoc
will produce some output; at worst, the output may be almost empty.
* New -Wunsupp message level.
--- POTENTIONALLY SECURITY RELEVANT BUGFIXES ---
* Fix a potential write buffer overrun on incomplete string conditionals.
http://mdocml.bsd.lv/cgi-bin/cvsweb/roff.c#rev1.241
* Fix a potential write buffer overrun on backslash at EOF in a conditional.
http://mdocml.bsd.lv/cgi-bin/cvsweb/roff.c#rev1.247

http://mdocml.bsd.lv/cgi-bin/cvsweb/mdoc_macro.c#rev1.180
--- MAJOR FUNCTIONALLY RELEVANT BUGFIXES ---

* roff(7): Don't let the modulo operator divide by zero.
* input: Fix an assertion failure on certain invalid UTF-8 input.
* terminal output: Allow arbitrary depth of the font stack (assertion fix).
* mdoc(7): Fix assertion failures and endless loops on invalid block closing.
* mdoc(7): Fix an assertion failure on .Bl .Sm not followed by .It.

* mandoc_char(7): Correct some character names and renderings.
* If earlier files set a non-zero exit status, never reset it to zero.

Changes in version 1.13.1, released on August 10, 2014
--- MAJOR NEW FEATURES ---
* A complete apropos(1)/makewhatis(8)/man.cgi(8) suite
based on SQLite3 is now included.
CAVEAT: This also requires a working fts(3) implementation.
If your system lacks that *and* you want apropos(1)/makewhatis(8),
stay with 1.12.3 for now, then go to 1.12.4 and 1.13.2.
[wiz: for this reason, the package does not enable these tools yet]
* The roff(7) parser now provides an almost complete implementation
of numerical expressions.
* Warning and error messages have been improved in many ways.
Almost all fatal errors were downgraded to normal errors and some
even to warnings. Almost all messages now mention the macro where
the issue is detected and many indicate the workaround employed.
The mandoc(1) manual now includes a list explaining all messages.
--- MINOR NEW FEATURES ---
* The roff(7) parser now supports the .ami (append to macro with
indirectly specified name), .as (append to user-defined
string), .dei (define macro with indirectly specified name),
.ll (line length), and .rr (remove register) requests.
* The roff(7) parser now supports string comparison and numerical
conditionals in the .if and .ie requests.
* The roff parser now fully supports the \B (validate numerical
expression) and partially supports the \w (measure text width)
escape sequences.
* The terminal formatter now supports the \: (optional line break)
escape sequence.
* The roff parser now supports expansion of user-defined strings
involving indirect references.
* The roff(7) parser now handles some pre-defined read-only
number registers that occur in the pod2man(1) preamble.
* For backward compatibility, the mdoc(7) parser and formatters
now support the obsolete macros .En, .Es, .Fr, and .Ot.
* The mdoc(7) formatter non partially supports .Bd -centered.
* tbl(7) now handles leading and trailing vertical lines.
* The build system now provides fallback versions of strcasestr(3)
and strsep(3) for systems lacking them.
* The mdoc(7) manual now explains how various standards
supported by the .St macro are related to each other.
--- BUGFIXES ---
* In the roff(7) parser, several bugs were fixed with respect
to closing conditional blocks on macro lines.
* Parsing of roff(7) identifiers and escape sequences was improved
in multiple respects.
* In the mdoc(7) parser, the handling of defective document
prologues was improved in multiple ways.
* The mdoc(7) parser no longer skips content before the first section
header, and it no longer deletes non-.% content from .Rs blocks.
* In the mdoc(7) parser, a crash was fixed related to weird .Sh headers.
* In the mdoc(7) parser, handling of .Sm with missing or invalid
arguments was corrected.
* In the mdoc(7) parser, trailing punctuation at the end of partial
implicit macros no longer triggers end-of-sentence spacing.
* In the terminal formatter, two crashes were fixed: one triggered by
excessive indentation and another by excessively long .Nm arguments.
* In the terminal formatter, a floating point rounding bug was
fixed that sometimes caused an off-by-one error in indentation.
* In the UTF-8 formatter, rendering of accents, breakable hyphens,
and non-breakable spaces was corrected.
* In the HTML formatter, encoding of special characters was
corrected in multiple respects.
* In the mdoc(7) formatter, rendering of .Ex and .Rv was
improved for various edge cases.
* In the mdoc(7) formatter, handling of empty .Bl -inset item
heads was improved.
* In the man(7) formatter, some bugs were fixed with respect
to same-line detection in the context of .TP and .nf macros,
and the indentation of .IP and .TP blocks was improved.
* The mandoc(3) library no longer prints to stderr.

Changes in version 1.12.3, released on December 31, 2013
* In the mdoc(7) SYNOPSIS, line breaks and hanging indentation
now work correctly for .Fo/.Fa/.Fc and .Fn blocks.
Thanks to Franco Fichtner for doing part of the work.
* The mdoc(7) .Bk macro got some addititonal bugfixes.
* In mdoc(7) macro arguments, double quotes can now be quoted
by doubling them, just like in man(7).
Thanks to Tsugutomo ENAMI for the patch.
* At the end of man(7) macro lines, end-of-sentence spacing
now works. Thanks to Franco Fichtner for the patch.
* For backward compatibility, the man(7) parser now supports the
man-ext .UR/.UE (uniform resource identifier) block macros.
* The man(7) parser now handles closing blocks that are not open
more gracefully.
* The man(7) parser now ignores blank lines right after .SH and .SS.
* In the man(7) formatter, reset indentation when leaving a block,
not just when entering the next one.
* The roff(7) .nr request now supports incrementing and decrementing
number registers and stops parsing the number right before the
first non-digit character.
* The roff(7) parser now supports the alternative escape sequence
syntax \C'uXXXX' for Unicode characters.
* The roff(7) parser now parses and ignores the .fam (font family)
and .hw (hyphenation points) requests and the \d and \u escape
sequences.
* The roff(7) manual got a new ESCAPE SEQUENCE REFERENCE.
Changes in version 1.12.2, released on Oktober 5, 2013
* The mdoc(7) to man(7) converter, to be called as mandoc -Tman,
is now fully functional.
* The mandoc(1) utility now supports the -Ios (default operating system)
input option, and the -Tutf8 output mode now actually works.
* The mandocdb(8) utility no longer truncates existing databases when
starting to build new ones, but only replaces them when the build
actually succeeds.
* The man(7) parser now supports the PD macro (paragraph distance),
and (for GNU man-ext compatibility only) EX (example block) and EE
(example end). Plus several bugfixes regarding indentation, line
breaks, and vertical spacing, and regarding RS following TP.
* The roff(7) parser now supports the \f(BI (bold+italic) font escape,
the \z (zero cursor advance) escape and the cc (change control
character) and it (input line trap) requests. Plus bugfixes regarding
the \t (tab) escape, nested escape sequences, and conditional requests.
* In mdoc(7), several bugs were fixed related to UTF-8 output of quoting
enclosures, delimiter handling, list indentation and horizontal and
vertical spacing, formatting of the Lk, %U, and %C macros, plus some
bugfixes related to the handling of syntax errors like badly nested
font blocks, stray Ta macros outside column lists, unterminated It Xo
blocks, and non-text children of Nm blocks.
* In tbl(7), the width of horizontal spans and the vertical spacing
around tables was corrected, and in man(7) files, a crash was fixed
that was triggered by some particular unclosed T{ macros.
* For mandoc developers, we now provide a tbl(3) library manual and
gmdiff, a very small, very simplistic groff-versus-mandoc output
comparison tool.
* Provide a NEWS file.
Changes in version 1.12.1, released on March 23, 2012
* Significant work on apropos(1) and mandocdb(8). These tools are now
much more robust. A whatis(1) implementation is now handled as an
apropos(1) mode. These tools are also able to minimally handle
pre-formatted pages, that is, those already formatted by another
utility such as GNU troff.
* The man.cgi(7) script is also now available for wider testing.
It interfaces with mandocdb(8) manuals cached by catman(8).
HTML output is generated on-the-fly by libmandoc or internal
methods to convert pre-formatted pages.
* The mailing list archive for the discuss and tech lists are being
hosted by Gmane at gmane.comp.tools.mdocml.user and
gmane.comp.tools.mdocml.devel, respectively.
conflicts with textproc/groff and allows both packages to co-exist,
paving the way for mdocml to be used in the tools infrastructure as an
nroff replacement.
Bump PKGREVISION.
02-09-2011: version 1.11.7
Added demandoc utility for stripping away macros and escapes. This
replaces the historical deroff utility. Also improved the mdoc and
man manuals.
16-08-2011: version 1.11.6
Handling of tr macro in roff implemented. This makes Perl documentation
much more readable. Hyphenation is also now enabled in man format
documents. Many other general improvements have been implemented.
Furthermore, a 64-bit Windows binary is now available at mdocml-win64.zip
and a Mac OS X universal binary is available at mdocml-macosx.zip.
24-07-2011: version 1.11.5
Significant eqn improvements. mdocml can now parse arbitrary eqn
input (although few GNU extensions are accepted, nor is mixing
low-level roff with eqn). See the eqn manual for details. For the
time being, equations are rendered as simple in-line text. The
equation parser satisfies the language specified in the Second
Edition User's Guide.
This is also the first release featuring a distributed Windows
binary, available at /binaries/mdocml-win32.zip.
12-07-2011: version 1.11.4
Bug-fixes and clean-ups across all systems, especially in makewhatis
(note: still not connected to the general build and must be compiled
with make makewhatis) and the man parser. This release was
significantly assisted by participants in OpenBSD's c2k11. Thanks!
26-05-2011: version 1.11.3
Introduce locale-encoding of output with the -Tlocale output option
and Unicode escaped-character input. See mandoc and mandoc_char,
respectively, for details. This allows for non-ASCII characters
(e.g., \[u5000]) to be rendered in the locale's encoding, if said
environment supports wide-character encoding (if it does not,
-Tascii is used instead). Locale support can be turned off at
compile time by removing -DUSE_WCHAR in the Makefile, in which case
-Tlocale is always a synonym for -Tascii.
Furthermore, multibyte-encoded documents, such as those in UTF-8,
may be on-the-fly recoded into mandoc input by using the newly-added
preconv utility. Note: in the future, this feature may be integrated
into mandoc.
12-05-2011: version 1.11.2
Corrected some installation issues in version 1.11.1. Further
migration to libmandoc. Initial public release (this utility is
very much under development) of makewhatis, initially named mandoc-db.
This utility produces keyword databases of manual content mandoc-cgi,
mandoc-tools, which features semantic querying of manual content.
The earlier libroff, libmdoc, and libman soup have been merged into
a single library, libmandoc, which manages all aspects of parsing
real manuals (from line-handling to tbl parsing).
Beyond this structural change, initial eqn functionality is in
place. For the time being, this is limited to the recognition of
equation blocks; future version of mdocml will expand upon this
framework.
As usual, many general fixes and improvements have also occured.
In particular, a great deal of redundancy and superfluous code has
been removed with the merging of the backend libraries.
