   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    * When a manual is missing from an outdated database, let man(1)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.
    * Fix a potential write buffer overrun on incomplete string conditionals.
    * Fix a potential write buffer overrun on backslash at EOF in a conditional.
    * Fix a use after free sometimes hit when validation deletes a block.
    * Let man(1) show manuals for the current architecture by default,
      and support the MACHINE environment variable.
    * Fix the man(1) and apropos(1) -m option, it didn't work at all.
    * Do not spawn a pager when there is no output.
    * In makewhatis(8), fix detection of hardlinked manuals on platforms
      having padding in struct inodev (typically 64bit platforms).
    * Ignore O_CLOEXEC when the operating system doesn't provide it.
    * Avoid forward reference to enum type which violates ISO C99.
    * Support homebrew-style linking on Mac OS X.
       --- MINOR NEW FEATURES ---
    * lookup: Accept digit+letter and "n" as section names in man(1),
      and consistently handle digit+letter in file name extensions.
    * lookup: Speed up -s/-S by using the "mlinks" rather than the "keys" table.
    * output: Insert horizontal lines between formatted manual pages.
    * input: New stricter and more resilient UTF-8 parser.
    * mdoc(7): Refactor block rewinding for simpler and more robust parsing.
    * man(7): Use the -Ios option when .TH has less than four arguments.
    * tbl(7): Implement the "center" option.

      and improved rendering of overstrikes in PostScript and PDF output.
    * Message improvements, in particular for, but not restricted to,
      eqn(7), tbl(7), and wrong numbers of arguments in mdoc(7) and man(7),
      in various cases also improving output generated by invalid input.
    * Delete the -V option.  It serves no purpose but keeps confusing people.
    * gmdiff: Minimal support for Heirloom roff.
    * tbl(7): Fix a read buffer overrun on 'f' at EOL in a layout.
    * roff(7): Fix a read buffer overrun on incomplete numerical conditions.
    * mdoc(7): Fix a NULL pointer access on .Nd followed by an explicit block.
    * mdoc(7): Fix a NULL pointer access on .It Xo without .Xc.
    * mdoc(7): Fix a NULL pointer access on .Eo without a tail.
    * mdoc(7): Fix a NULL pointer access in the validation of empty .St macros.
    * man(7)/tbl(7): Fix a NULL pointer access on .TS right after .TP.
    * tbl(7): Fix a NULL pointer access on layout lines without any cells.
    * eqn(7): Fix NULL pointer accesses in the terminal formatter.
    * roff(7): Fix a NULL pointer access on trailing \s-/\s+ without an argument.
    * gz: Fix a potential NULL pointer access after waitpid() failure.
    * 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.
    * mdoc(7): Fix an assertion failure on .Bl -column ... .El .Ta.
    * tbl(7): Fix assertion failures by macros inside table data,
      but do not throw away the macro arguments.
    * Prevent certain kinds of unreasonable input from producing excessive
      output, in one case caused by unsigned integer underflow.
    * Fix a potential memory leak in makewhatis(8) on very long filenames.
       --- MINOR BUGFIXES ---
    * mdoc(7): Fix parsing of badly nested blocks with multiple identical blocks.
    * mdoc(7): Support negative indentations for displays and lists.
    * mdoc(7): Don't mistreat negative .sp arguments as large positive ones.

    * roff(7): Slightly improve \w width measurements.
    * roff(7): Accept the historic aliases \s10 to \s39 for \s(10 to \s(39.
    * roff(7): Correctly escape quotes when expanding macro arguments.
    * roff(7): Correctly handle scaling units in numerical expressions,
      and some other improvements to the parsing of numerical expressions.
    * roff(7): Three minor fixes with respect to evaluation of conditionals.
    * roff(7): Let .it accept numerical expressions, not just constants.
    * mandoc_char(7): Correct some character names and renderings.
    * If earlier files set a non-zero exit status, never reset it to zero.
