branches: 1.1.1.1.2; 1.1.1.1.4;

Changes in version 1.14.1, released on February 21, 2017

--- MAJOR NEW FEATURES ---
* apropos(1): Reimplement complete semantic search functionality
without the dependency on SQLite3, using only POSIX APIs.
This comes with a completely new mandoc.db(5) file format.
* man(1): Support more than one tag entry for the same search term,
plus some minor improvements to the less(1) :t support.
* -Thtml: Use real macro names for CSS classes.
Systematic cleanup of and many improvements to mandoc.css.
* -Thtml: Produce human readable HTML code by using indentation
and better line breaks. Improve various HTML elements,
and trim several useless ones.
* New catman(8) utility, still somewhat experimental.
* Now includes a portable version of the OpenBSD mandoc regression
suite, see regress/regress.pl.1 for details.
--- REMOVED FUNCTIONALITY ---
* Operating systems that don't provide mmap(3) are no longer supported.
* Drop support for manpath(1). Even if your system has manpath(1),
it is simpler to use MANPATH_DEFAULT in configure.local for
operating system defaults, man.conf(5) for machine-specific
modifications, and ${MANPATH}, -m, and -M for user preferences
than to bother with the complexity of manpath(1).
* makewhatis(8) -p: No longer warn about missing MLINKS since these
are no longer needed for anything.
--- MINOR NEW FEATURES ---
* mdoc(7): Warn about invalid punctuation and content below NAME.
* mdoc(7): Warn about .Xr lacking the second argument (section).
* mdoc(7): Warn about violations of the rule "new sentence, new line".
* roff(7): Warn about trailing whitespace at the end of comments.
* mdoc(7): Improve rendering of double quotes.
* mdoc(7): Always do text production in the validator, never in the
formatters. Cleaner, simpler, shorter, helps NetBSD apropos(1)
and also makes -Ttree output more useful.
* -Ttree: Show metadata and some additional node flags.
New -Onoval output option to show the unvalidated tree.
--- RELIABILITY BUGFIXES ---
* man(1): Make "man -l" work with standard input from a pipe or file,
as long as standard output is a terminal.
* man(7): Fix out of bounds read access if a text node immediately
preceded the first .SH header.
* mdoc(7): Fix out of bounds read access for .Bl without a type
but with a width.
* mdoc(7): Fix out of bounds read access for .Bl -column starting
with a tab character instead of a child .It macro.
* mdoc(7): Fix syntax tree corruption leading to segfaults caused
by stray block end macros in nested blocks of mismatching type.
* man(1): Fix NULL dereference when the first of multiple pages
shown was preformatted.
* mdoc(7): Fix syntax tree corruption leading to NULL dereference
caused by partial implicit macros inside .Bl -column table cells.
* mdoc(7): Fix syntax tree corruption leading to NULL dereference
for macro sequences like .Bl .Bl .It Bo .El .It.
* mdoc(7): Fix syntax tree corruption leading to NULL dereference
caused by .Ta following a nested .Bl -column breaking another block.
* mdoc(7): Fix syntax tree corruption sometimes leading to NULL
dereference caused by indirectly broken .Nd or .Nm blocks.
* mdoc(7) -Thtml: Fix a NULL dereference for .Bl -column with 0 columns.
* mdoc(7): Fix NULL dereference in some specific cases of a
block-end macro calling another block-end macro.
* mdoc(7): Fix NULL dereference if the only child of the head
of the first .Sh was an empty in-line macro.
* eqn(7): Fix NULL dereference in the terminal formatter
for empty matrices and empty square roots.
* mdoc(7): Fix an assertion failure for a .Bd without a type that
breaks another block.
* mdoc(7): Fix an assertion failure that happened for some .Bl -column
lists containing a column width of "-4n", "-3n", or "-2n".
* mdoc(7): Fix an assertion failure caused by .Bl -column without .It
but containing eqn(7) or tbl(7) code.
* roff(7): Fix an assertion failure caused by \z\[u00FF] with -Tps/-Tpdf.
* roff(7): Fix an assertion failures caused by whitespace inside \o''
(overstrike) sequences.
* -Thtml: Fix an assertion failure caused by -Oman or -Oincludes of
excessive length.
--- PORTABILITY IMPROVEMENTS ---
* man(1): Do not mix stdio narrow and wide stream orientation
on stdout, which could cause output corruption on glibc.
* mandoc(1): Autodetect a suitable locale for -Tutf8 mode.
* ./configure: Autodetect whether PATH_MAX and O_DIRECTORY are defined.
* ./configure: Autodetect if nanosleep(3) needs -lrt.
* ./configure: Provide an ${LN} configuration variable.
* ./configure: Put compiler arguments that may contain -l at the end.
--- MINOR BUGFIXES ---
* mdoc(7): Fix SYNOPSIS output if the first child of .Nm is a macro.
* mdoc(7) -Thtml: Improve formatting of .Bl -tag with short tags.
* man(7) -Thtml: Preserve whitespace in .nf (nofill) mode.
* mandoc(1): Error out on invalid output options on the command line.
--- STRUCTURAL CHANGES, no functional change ---
* Redesign part of the mandoc_html(3) interfaces, making them much
easier to use and reducing the amount of code by a few hundred lines.
--- THANKS TO ---
* Michael Stapelberg (Debian) for designing the new mandocd(8)
and parts of the new catman(8), for release testing, and for a
number of patches and bug reports.
* Baptiste Daroussin (FreeBSD) for profiling the new makewhatis(8)
implementation and suggesting an algorithmic improvement which
more than doubled performance, and for a few bug reports.
* Ed Maste (FreeBSD) for an important patch improving reproducibility
of builds in makewhatis(8), and for a few bug reports.
* Theo Buehler (OpenBSD) for almost twenty important bug reports,
most of them found by systematic afl(1) fuzzing.
* Benny Lofgren, David Dahlberg, and in particular Vadim Zhukov
for crucial help in getting .Bl -tag CSS formatting fixed.
* Svyatoslav Mishyn (Crux Linux) for an initial version of the
patch to autodetect a suitable locale for -Tutf8 mode
and for release testing.
