+
+This file lists the most important changes in the mandoc.bsd.lv distribution.
+
+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.

+ and parts of the new catman(8), for release testing, and for a
+ number of patches and bug reports.

+
+ --- MAJOR NEW FEATURES ---

+ based on SQLite3 is now included.
+ * The roff(7) parser now provides an almost complete implementation
+ of numerical expressions.

+ 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)

+ --- 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.
