Changes in version 1.12.2, released on Oktober 1, 2013 |
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* When a manual is missing from an outdated database, let man(1) |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 |

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. |
|
* 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. |
