560: --- BUGFIXES ---
561: * In the roff(7) parser, several bugs were fixed with respect
562: to closing conditional blocks on macro lines.
563: * Parsing of roff(7) identifiers and escape sequences was improved
564: in multiple respects.
565: * In the mdoc(7) parser, the handling of defective document
566: prologues was improved in multiple ways.
567: * The mdoc(7) parser no longer skips content before the first section
568: header, and it no longer deletes non-.% content from .Rs blocks.
569: * In the mdoc(7) parser, a crash was fixed related to weird .Sh headers.
570: * In the mdoc(7) parser, handling of .Sm with missing or invalid

576: * In the terminal formatter, a floating point rounding bug was
577: fixed that sometimes caused an off-by-one error in indentation.
578: * In the UTF-8 formatter, rendering of accents, breakable hyphens,
579: and non-breakable spaces was corrected.
580: * In the HTML formatter, encoding of special characters was
581: corrected in multiple respects.
582: * In the mdoc(7) formatter, rendering of .Ex and .Rv was
583: improved for various edge cases.
584: * In the mdoc(7) formatter, handling of empty .Bl -inset item
585: heads was improved.
586: * In the man(7) formatter, some bugs were fixed with respect
587: to same-line detection in the context of .TP and .nf macros,
588: and the indentation of .IP and .TP blocks was improved.
589: * The mandoc(3) library no longer prints to stderr.

603: * In the mdoc(7) SYNOPSIS, line breaks and hanging indentation
604: now work correctly for .Fo/.Fa/.Fc and .Fn blocks.
605: Thanks to Franco Fichtner for doing part of the work.
606: * The mdoc(7) .Bk macro got some addititonal bugfixes.
607: * In mdoc(7) macro arguments, double quotes can now be quoted
608: by doubling them, just like in man(7).
609: Thanks to Tsugutomo ENAMI for the patch.
610: * At the end of man(7) macro lines, end-of-sentence spacing
611: now works. Thanks to Franco Fichtner for the patch.
612: * For backward compatibility, the man(7) parser now supports the
613: man-ext .UR/.UE (uniform resource identifier) block macros.
614: * The man(7) parser now handles closing blocks that are not open
615: more gracefully.
616: * The man(7) parser now ignores blank lines right after .SH and .SS.
617: * In the man(7) formatter, reset indentation when leaving a block,
618: not just when entering the next one.
619: * The roff(7) .nr request now supports incrementing and decrementing
620: number registers and stops parsing the number right before the
621: first non-digit character.
622: * The roff(7) parser now supports the alternative escape sequence
623: syntax \C'uXXXX' for Unicode characters.
624: * The roff(7) parser now parses and ignores the .fam (font family)
625: and .hw (hyphenation points) requests and the \d and \u escape

1.2 schwarze 629: Changes in version 1.12.2, released on Oktober 5, 2013
1.1 schwarze 630:
631: * The mdoc(7) to man(7) converter, to be called as mandoc -Tman,
632: is now fully functional.
633: * The mandoc(1) utility now supports the -Ios (default operating system)
634: input option, and the -Tutf8 output mode now actually works.
635: * The mandocdb(8) utility no longer truncates existing databases when
636: starting to build new ones, but only replaces them when the build
637: actually succeeds.
638: * The man(7) parser now supports the PD macro (paragraph distance),
639: and (for GNU man-ext compatibility only) EX (example block) and EE
640: (example end). Plus several bugfixes regarding indentation, line
641: breaks, and vertical spacing, and regarding RS following TP.
642: * The roff(7) parser now supports the \f(BI (bold+italic) font escape,
643: the \z (zero cursor advance) escape and the cc (change control
644: character) and it (input line trap) requests. Plus bugfixes regarding
645: the \t (tab) escape, nested escape sequences, and conditional requests.
646: * In mdoc(7), several bugs were fixed related to UTF-8 output of quoting
647: enclosures, delimiter handling, list indentation and horizontal and
648: vertical spacing, formatting of the Lk, %U, and %C macros, plus some
649: bugfixes related to the handling of syntax errors like badly nested
650: font blocks, stray Ta macros outside column lists, unterminated It Xo
651: blocks, and non-text children of Nm blocks.
652: * In tbl(7), the width of horizontal spans and the vertical spacing
653: around tables was corrected, and in man(7) files, a crash was fixed
654: that was triggered by some particular unclosed T{ macros.
655: * For mandoc developers, we now provide a tbl(3) library manual and
656: gmdiff, a very small, very simplistic groff-versus-mandoc output
657: comparison tool.
1.2 schwarze 658: * Provide this NEWS file.
1.1 schwarze 659:
660: Changes in version 1.12.1, released on March 23, 2012
661:
662: * Significant work on apropos(1) and mandocdb(8). These tools are now
663: much more robust. A whatis(1) implementation is now handled as an
664: apropos(1) mode. These tools are also able to minimally handle
665: pre-formatted pages, that is, those already formatted by another
666: utility such as GNU troff.
667: * The man.cgi(7) script is also now available for wider testing.
668: It interfaces with mandocdb(8) manuals cached by catman(8).
669: HTML output is generated on-the-fly by libmandoc or internal
670: methods to convert pre-formatted pages.
671: * The mailing list archive for the discuss and tech lists are being
672: hosted by Gmane at gmane.comp.tools.mdocml.user and
673: gmane.comp.tools.mdocml.devel, respectively.
674:
675: Changes in version 1.12.0, released on October 8, 2011
676:
677: * This version features a new, work-in-progress mandoc(1) output mode:
678: -Tman. This mode allows a system maintainer to distribute man(7)
679: media for older systems that may not natively support mdoc(7), such
680: as old Solaris systems.
681: * The -Ofragment option was added to mandoc(1)'s -Thtml and -Txhtml modes.
682: * While adding features, an apropos(1) utility has been merged from the
683: mandoc-tools sandbox. This interfaces with mandocdb(8) for semantic
684: search of manual content. apropos(1) is different from the traditional
685: apropos primarily in allowing keyword search (such as for functions,
686: utilities, etc.) and regular expressions. Note that the calling
687: syntax for apropos is likely to change as it settles down.
688: * In documentation news, the mdoc(7) and man(7) manuals have been
689: made considerably more readable by adding MACRO OVERVIEW sections, by
690: moving the gory details of the LANGUAGE SYNTAX to the roff(7) manual,
691: and by moving the very technical MACRO SYNTAX sections down to the
692: bottom of the page.
693: * Furthermore, for tbl(7), the -Tascii mode horizontal spacing of tables
694: was rewritten completely. It is now compatible with groff(1), both
695: with and without frames and rulers.
696: * Nesting of indented blocks is now supported in man(7), and several
697: bugs were fixed regarding indentation and alignment.
698: * The page headers in mdoc(7) are now nicer for very long titles.
699:
700: Changes in version 1.11.7, released on September 2, 2011
701:
702: * Added demandoc(1) utility for stripping away macros and escapes.
703: This replaces the historical deroff(1) utility.
704: * Also improved the mdoc(7) and man(7) manuals.
705:
706: Changes in version 1.11.6, released on August 16, 2011
707:
708: * Handling of tr macro in roff(7) implemented. This makes Perl
709: documentation much more readable. Hyphenation is also now enabled in
710: man(7) format documents. Many other general improvements have been
711: implemented.
712:
713: Changes in version 1.11.5, released on July 24, 2011
714:
715: * Significant eqn(7) improvements. mdocml can now parse arbitrary eqn
716: input (although few GNU extensions are accepted, nor is mixing
717: low-level roff with eqn). See the eqn(7) manual for details.
718: For the time being, equations are rendered as simple in-line text.
719: The equation parser satisfies the language specified in the
720: Second Edition User's Guide:
721: http://www.kohala.com/start/troff/v7man/eqn/eqn2e.ps
722:
723: Changes in version 1.11.4, released on July 12, 2011
724:
725: * Bug-fixes and clean-ups across all systems, especially in mandocdb(8)
726: and the man(7) parser. This release was significantly assisted by
727: participants in OpenBSD's c2k11. Thanks!
728:
729: Changes in version 1.11.3, released on May 26, 2011
730:
731: * Introduce locale-encoding of output with the -Tlocale output option and
732: Unicode escaped-character input. See mandoc(1) and mandoc_char(7),
733: respectively, for details. This allows for non-ASCII characters (e.g.,
734: \[u5000]) to be rendered in the locale's encoding, if said environment
735: supports wide-character encoding (if it does not, -Tascii is used
736: instead). Locale support can be turned off at compile time by removing
737: -DUSE_WCHAR in the Makefile, in which case -Tlocale is always a synonym
738: for -Tascii.
739: * Furthermore, multibyte-encoded documents, such as those in UTF-8, may
740: be on-the-fly recoded into mandoc(1) input by using the newly-added
741: preconv(1) utility. Note: in the future, this feature may be
742: integrated into mandoc(1).
743:
744: Changes in version 1.11.2, released on May 12, 2011
745:
746: * Corrected some installation issues in version 1.11.1.
747: * Further migration to libmandoc.
748: * Initial public release (this utility is very much under development)
749: of mandocdb(8). This utility produces keyword databases of manual
750: content, which features semantic querying of manual content.
751:
752: Changes in version 1.11.1, released on April 4, 2011
753:
754: * The earlier libroff, libmdoc, and libman soup have been merged into
755: a single library, libmandoc, which manages all aspects of parsing
756: real manuals, from line-handling to tbl(7) parsing.
757: * As usual, many general fixes and improvements have also occurred.
758: In particular, a great deal of redundancy and superfluous code has
759: been removed with the merging of the backend libraries.
1.3 schwarze 760: * see also the changes in 1.10.10
761:
762: Changes in version 1.10.10, March 20, 2011, NOT released
763:
764: * Initial eqn(7) functionality is in place. For the time being,
765: this is limited to the recognition of equation blocks;
766: future version of mdocml will expand upon this framework.

770: * Many back-end fixes have been implemented: argument handling (quoting),
771: man(7) improvements, error/warning classes, and many more.
772: * Initial tbl(7) functionality (see the "TS", "TE", and "T&" macros in
773: the roff(7) manual) has been merged from tbl.bsd.lv. Output is still
774: minimal, especially for -Thtml and -Txhtml, but manages to at least
775: display data. This means that mandoc(1) now has built-in support
776: for two troff preprocessors via libroff: soelim(1) and tbl(1).
777:
778: Changes in version 1.10.8, released on December 24, 2010
779:
1.3 schwarze 780: * Overhauled the -Thtml and -Txhtml output modes. They now display
1.1 schwarze 781: readable output in arbitrary browsers, including text-based ones like
782: lynx(1). See HTML and XHTML manuals in the DOCUMENTATION section
783: for examples. Attention: available style-sheet classes have been
784: considerably changed! See the example.style.css file for details.
785: Lastly, libmdoc and libman have been cleaned up and reduced in size
786: and complexity.
1.3 schwarze 787: * see also the changes in 1.10.7
788:
789: Changes in version 1.10.7, December 6, 2010, NOT released
790:
791: Significant improvements merged from OpenBSD downstream, including:
792: * many new roff(7) components,
793: * in-line implementation of troff's soelim(1),
794: * broken-block handling,
795: * overhauled error classifications, and
796: * cleaned up handling of error conditions.
1.1 schwarze 797:
798: Changes in version 1.10.6, released on September 27, 2010
799:
800: * Calling conventions for mandoc(1) have changed: -W improved and -f
801: deprecated.
802: * Non-ASCII characters are also now uniformly discarded.
803: * Lots of documentation improvements.
804: * Many incremental fixes accomodating for groff's more interesting
805: productions.
806: * Lastly, pod2man(1) preambles are now fully accepted after some
807: considerable roff(7) and special character support.
808:
809: Changes in version 1.10.5, released on July 27, 2010
810:
811: * Primarily a bug-fix and polish release, but including -Tpdf support
812: in mandoc(1) by way of "Summer of Code". Highlights:
813: * fix "Sm" and "Bd" handling
814: * fix end-of-sentence handling for embedded sentences
815: * polish man(7) documentation
816: * document all mdoc(7) macros
817: * polish mandoc(1) -Tps output
818: * lots of internal clean-ups in character escapes
819: * un-break literal contexts in man(7) documents
820: * improve -Thtml output for -man
821: * add mandoc(1) -Tpdf support
822:
823: Changes in version 1.10.4, released on July 12, 2010
824:
825: * Lots of features developed during both "Summer of Code" and the
826: OpenBSD c2k10 hackathon:
827: * minimal "ds" roff(7) symbols are supported
828: * beautified SYNOPSIS section output
829: * acceptance of scope-block breakage in mdoc(7)
830: * clarify error message status
831: * many minor bug-fixes and formatting issues resolved
1.3 schwarze 832: * see also changes in 1.10.3
833:
834: Changes in version 1.10.3, June 29, 2010, NOT released
835:
836: * variable font-width and paper-size support in mandoc(1) -Tps output
837: * "Bk" mdoc(7) support
1.1 schwarze 838:
839: Changes in version 1.10.2, released on June 19, 2010
840:
841: * Small release featuring text-decoration in -Tps output,
842: a few minor relaxations of errors, and some optimisations.
843:
844: Changes in version 1.10.1, released on June 7, 2010
845:
846: * This primarily focusses on the "Bl" and "It" macros described in
847: mdoc(7). Multi-line column support is now fully compatible with groff,
848: as are implicit list entries for columns.
849: * Removed manuals(7) in favour of http://manpages.bsd.lv.
850: * The way we handle the SYNOPSIS section (see the SYNOPSIS documentation
851: in MANUAL STRUCTURE) has also been considerably simplified compared
852: to groff's method.
853: * Furthermore, the -Owidth=width output option has been added to -Tascii,
854: see mandoc(1).
855: * Lastly, initial PostScript output has been added with the -Tps option
856: to mandoc(1). It's brutally simple at the moment: fixed-font, with no
857: font decorations.
858:
859: Changes in version 1.10.0, released on May 29, 2010
860:
861: * Release consisting of the results from the m2k10 hackathon and up-merge
862: from OpenBSD. This requires a significant note of thanks to Ingo
863: Schwarze (OpenBSD) and Joerg Sonnenberger (NetBSD) for their hard work,
864: and again to Joerg for hosting m2k10. Highlights (mostly cribbed from
865: Ingo's m2k10 report) follow in no particular order:
866: * a libroff preprocessor in front of libmdoc and libman stripping out
867: roff(7) instructions;
868: * end-of-sentence (EOS) detection in free-form and macro lines;
869: * correct handling of tab-separated columnar lists in mdoc(7);
870: * improved main calling routines to optionally use mmap(3) for better
871: performance;
872: * cleaned up exiting when invoked as -Tlint or over multiple files
873: with -fign-errors;
874: * error and warning message handling re-written to be unified for
875: libroff, libmdoc, and libman;
876: * handling of badly-nested explicit-scoped macros;
877: * improved free-form text parsing in libman and libmdoc;
878: * significant GNU troff compatibility improvements in -Tascii,
879: largely in terms of spacing;
880: * a regression framework for making sure the many fragilities of GNU
881: troff aren't trampled in subsequent work;
882: * support for -Tascii breaking at hyphens encountered in free-form text;
883: * and many more minor fixes and improvements
884:
885: Changes in version 1.9.25, released on May 13, 2010
886:
887: * Fixed handling of "\*(Ba" escape.
888: * Backed out -fno-ign-chars (pointless complexity).
889: * Fixed erroneous breaking of literal lines.
890: * Fixed SYNOPSIS breaking lines before non-initial macros.
891: * Changed default section ordering.
892: * Most importantly, the framework for end-of-sentence double-spacing is
893: in place, now implemented for the "end-of-sentence, end-of-line" rule.
894: * This is a stable roll-back point before the mandoc hackathon in Rostock!
895:
896: Changes in version 1.9.24, released on May 9, 2010
897:
898: * Rolled back break-at-hyphen.
899: * -DUGLY is now the default (no feature splits!).
900: * Free-form text is not de-chunked any more: lines are passed
901: whole-sale into the front-end, including whitespace.
902: * Added mailing lists.
903:
904: Changes in version 1.9.23, released on April 7, 2010
905:
906: * mdocml has been linked to the OpenBSD build.
907: * This version incorporates many small changes, mostly from patches
908: by OpenBSD, allowing crufty manuals to slip by with warnings instead
909: of erroring-out.
910: * Some subtle semantic issues, such as punctuation scope, have also
911: been fixed.
912: * Lastly, some issues with -Thtml have been fixed, which prompted an
913: update to the online manual pages style layout.
914:
915: Changes in version 1.9.22, released on March 31, 2010
916:
917: * Adjusted merge of the significant work by Ingo Schwarze
918: in getting "Xo" blocks (block full implicit, e.g., "It"
919: for non-columnar lists) to work properly. This isn't
920: enabled by default: you must specify -DUGLY as a compiler
921: flag (see the Makefile for details).
922:
923: Changes in version 1.9.20, released on March 30, 2010
924:
925: * More efforts to get roff instructions in man(7) documents under
926: control. Note that roff instructions embedded in line-scoped,
927: next-line macros (e.g. "B") are not supported.
928: * Leading punctuation for mdoc(7) macros, such as "Fl ( ( a",
929: are now correctly handled.
930:
931: Changes in version 1.9.18, released on March 27, 2010
932:
933: * Many fixes (largely pertaining to scope)
934: and improvements (e.g., handling of apostrophe-control macros,
935: which fixes the strange "BR" seen in some macro output)
936: to handling roff instructions in man(7) documents.
937:
938: Changes in version 1.9.17, released on March 25, 2010
939:
940: * Accept perlpod(1) standard preamble.
941: * Also accept (and discard) "de", "dei", "am", "ami", and "ig"
942: roff macro blocks.
943:
944: Changes in version 1.9.16, released on March 22, 2010
945:
946: * Inspired by patches and bug reports by Ingo Schwarze,
947: allowed man(7) to accept non-printing elements to be nested
948: within next-line scopes, such as "br" within "B" or "TH",
949: which is valid roff.
950: * Longsoon architecture also noted and Makefile cleaned up.
951:
952: Changes in version 1.9.15, released on February 18, 2010
953:
954: * Moved to our new BSD.lv home.
955: * XHTML is now an acceptable output mode for mandoc(1);
956: * "Xr" made more compatible with groff;
957: * "Vt" fixed when invoked in SYNOPSIS;
958: * "\\" escape removed;
959: * end-of-line white-space detected for all lines;
960: * subtle bug fixed in list display for some modes;
961: * compatibility layer checked in for compilation in diverse
962: UNIX systems;
963: * and column lengths handled correctly.
