1.28 schwarze 6:
7: --- MAJOR NEW FEATURES ---
8: * In ASCII output, render mathematical symbols and greek letters
9: as transliterations conveying the characters' meanings rather
10: than trying to imitate their shape. Consequently, such characters
11: can now be used in portable manual pages. All the same, please
12: limit their use to contexts where they really matter, for example
13: when showing complicated mathematical formulae.
14: * First steps towards better support for small screens in HTML
15: output (responsive design): avoid most style= attributes, in
16: particular all hard-coded indentations and column widths, and
17: provide a better mandoc.css style sheet with a @media query,
18: using em units throughout, and avoiding redundancy in selectors.
19: * Better HTML output with some more fitting HTML elements, eliminating
20: needless class= attributes, and avoiding various HTML syntax errors
21: (element nesting, URL-fragment syntax, duplicate id= attributes).
22: --- MINOR NEW FEATURES ---
23: * When a man(1) argument contains a slash, imply -l like in man-db.
24: * Use TIOCGWINSZ to reduce the default -Owidth and -Oindent during
25: interactive use on terminals narrower than 79 columns.
26: * Generated PostScript files are now more than 50% smaller.
27: * Terminal rendering of eqn(7) is improved in several respects.
28: * Simplified and nicer output from the mdoc(7) .Lk macro, formatting
29: all links in-line, even long ones.
30: * roff(7) \n+ and \n- numerical register auto-increment and -decrement
31: * roff(7) .nr optional third argument (auto-increment step size)
1.29 schwarze 32: * Autodetect in ./configure whether the compiler can use -W and -static,
33: allowing to build on Solaris 10 and 11 without any configure.local.
1.28 schwarze 34: --- RELIABILITY BUGFIXES ---
35: * Only activate UTF-8 output when the user really selected UTF-8,
36: not some other multibyte character encoding.
37: * Prevent excessive .ll arguments from generating infinite output.
1.31 schwarze 38: * Fix out of bounds accesses to parse buffers that could happen when
39: using renamed or user defined macros after roff(7) conditionals.
1.28 schwarze 40: * Avoid an assertion failure in certain .Bl -column lists.
41: * Avoid a NULL pointer access on deroff() failure after '.SS ""'.
42: * Fix a segfault that could be triggered by two invalid .Dt macros.
43: * Fix two syntax errors in generated PDF files.
44: * Properly state the page size in generated PostScript files.
45: * Close a memory leak caused by missing gzclose(3).
46: * Fix misformatting of man(7) documents lacking .SH macros
47: in PostScript and PDF output.
48: * And many minor bugfixes.

242: block-end macro calling another block-end macro.
1.13 schwarze 243: * mdoc(7): Fix NULL dereference if the only child of the head
244: of the first .Sh was an empty in-line macro.

766: * Significant work on apropos(1) and mandocdb(8). These tools are now
767: much more robust. A whatis(1) implementation is now handled as an
768: apropos(1) mode. These tools are also able to minimally handle
769: pre-formatted pages, that is, those already formatted by another
770: utility such as GNU troff.
771: * The man.cgi(7) script is also now available for wider testing.
772: It interfaces with mandocdb(8) manuals cached by catman(8).
773: HTML output is generated on-the-fly by libmandoc or internal
774: methods to convert pre-formatted pages.
775: * The mailing list archive for the discuss and tech lists are being
776: hosted by Gmane at gmane.comp.tools.mdocml.user and
777: gmane.comp.tools.mdocml.devel, respectively.
778:
779: Changes in version 1.12.0, released on October 8, 2011
780:
781: * This version features a new, work-in-progress mandoc(1) output mode:
782: -Tman. This mode allows a system maintainer to distribute man(7)
783: media for older systems that may not natively support mdoc(7), such
784: as old Solaris systems.
785: * The -Ofragment option was added to mandoc(1)'s -Thtml and -Txhtml modes.
786: * While adding features, an apropos(1) utility has been merged from the
787: mandoc-tools sandbox. This interfaces with mandocdb(8) for semantic
788: search of manual content. apropos(1) is different from the traditional
789: apropos primarily in allowing keyword search (such as for functions,
790: utilities, etc.) and regular expressions. Note that the calling
791: syntax for apropos is likely to change as it settles down.
792: * In documentation news, the mdoc(7) and man(7) manuals have been
793: made considerably more readable by adding MACRO OVERVIEW sections, by
794: moving the gory details of the LANGUAGE SYNTAX to the roff(7) manual,
795: and by moving the very technical MACRO SYNTAX sections down to the
796: bottom of the page.
797: * Furthermore, for tbl(7), the -Tascii mode horizontal spacing of tables
798: was rewritten completely. It is now compatible with groff(1), both
799: with and without frames and rulers.
800: * Nesting of indented blocks is now supported in man(7), and several
801: bugs were fixed regarding indentation and alignment.
802: * The page headers in mdoc(7) are now nicer for very long titles.
803:
804: Changes in version 1.11.7, released on September 2, 2011
805:
806: * Added demandoc(1) utility for stripping away macros and escapes.
807: This replaces the historical deroff(1) utility.
808: * Also improved the mdoc(7) and man(7) manuals.
809:
810: Changes in version 1.11.6, released on August 16, 2011
811:
812: * Handling of tr macro in roff(7) implemented. This makes Perl
813: documentation much more readable. Hyphenation is also now enabled in
814: man(7) format documents. Many other general improvements have been
815: implemented.
816:
817: Changes in version 1.11.5, released on July 24, 2011
818:
819: * Significant eqn(7) improvements. mdocml can now parse arbitrary eqn
820: input (although few GNU extensions are accepted, nor is mixing
821: low-level roff with eqn). See the eqn(7) manual for details.
822: For the time being, equations are rendered as simple in-line text.
823: The equation parser satisfies the language specified in the
824: Second Edition User's Guide:
825: http://www.kohala.com/start/troff/v7man/eqn/eqn2e.ps
826:
827: Changes in version 1.11.4, released on July 12, 2011
828:
829: * Bug-fixes and clean-ups across all systems, especially in mandocdb(8)
830: and the man(7) parser. This release was significantly assisted by
831: participants in OpenBSD's c2k11. Thanks!
832:
833: Changes in version 1.11.3, released on May 26, 2011
834:
835: * Introduce locale-encoding of output with the -Tlocale output option and
836: Unicode escaped-character input. See mandoc(1) and mandoc_char(7),
837: respectively, for details. This allows for non-ASCII characters (e.g.,
838: \[u5000]) to be rendered in the locale's encoding, if said environment
839: supports wide-character encoding (if it does not, -Tascii is used
840: instead). Locale support can be turned off at compile time by removing
841: -DUSE_WCHAR in the Makefile, in which case -Tlocale is always a synonym
842: for -Tascii.
843: * Furthermore, multibyte-encoded documents, such as those in UTF-8, may
844: be on-the-fly recoded into mandoc(1) input by using the newly-added
845: preconv(1) utility. Note: in the future, this feature may be
846: integrated into mandoc(1).
847:
848: Changes in version 1.11.2, released on May 12, 2011
849:
850: * Corrected some installation issues in version 1.11.1.
851: * Further migration to libmandoc.
852: * Initial public release (this utility is very much under development)
853: of mandocdb(8). This utility produces keyword databases of manual
854: content, which features semantic querying of manual content.
855:
856: Changes in version 1.11.1, released on April 4, 2011
857:
858: * The earlier libroff, libmdoc, and libman soup have been merged into
859: a single library, libmandoc, which manages all aspects of parsing
860: real manuals, from line-handling to tbl(7) parsing.
861: * As usual, many general fixes and improvements have also occurred.
862: In particular, a great deal of redundancy and superfluous code has
863: been removed with the merging of the backend libraries.
1.3 schwarze 864: * see also the changes in 1.10.10
865:
866: Changes in version 1.10.10, March 20, 2011, NOT released
867:
868: * Initial eqn(7) functionality is in place. For the time being,
869: this is limited to the recognition of equation blocks;
870: future version of mdocml will expand upon this framework.
1.1 schwarze 871:
872: Changes in version 1.10.9, released on January 7, 2011
873:
874: * Many back-end fixes have been implemented: argument handling (quoting),
875: man(7) improvements, error/warning classes, and many more.
876: * Initial tbl(7) functionality (see the "TS", "TE", and "T&" macros in
877: the roff(7) manual) has been merged from tbl.bsd.lv. Output is still
878: minimal, especially for -Thtml and -Txhtml, but manages to at least
879: display data. This means that mandoc(1) now has built-in support
880: for two troff preprocessors via libroff: soelim(1) and tbl(1).
881:
882: Changes in version 1.10.8, released on December 24, 2010
883:
1.3 schwarze 884: * Overhauled the -Thtml and -Txhtml output modes. They now display
1.1 schwarze 885: readable output in arbitrary browsers, including text-based ones like
886: lynx(1). See HTML and XHTML manuals in the DOCUMENTATION section
887: for examples. Attention: available style-sheet classes have been
888: considerably changed! See the example.style.css file for details.
889: Lastly, libmdoc and libman have been cleaned up and reduced in size
890: and complexity.
1.3 schwarze 891: * see also the changes in 1.10.7
892:
893: Changes in version 1.10.7, December 6, 2010, NOT released
894:
895: Significant improvements merged from OpenBSD downstream, including:
896: * many new roff(7) components,
897: * in-line implementation of troff's soelim(1),
898: * broken-block handling,
899: * overhauled error classifications, and
900: * cleaned up handling of error conditions.
1.1 schwarze 901:
902: Changes in version 1.10.6, released on September 27, 2010
903:
904: * Calling conventions for mandoc(1) have changed: -W improved and -f
905: deprecated.
906: * Non-ASCII characters are also now uniformly discarded.
907: * Lots of documentation improvements.
908: * Many incremental fixes accomodating for groff's more interesting
909: productions.
910: * Lastly, pod2man(1) preambles are now fully accepted after some
911: considerable roff(7) and special character support.
912:
913: Changes in version 1.10.5, released on July 27, 2010
914:
915: * Primarily a bug-fix and polish release, but including -Tpdf support
916: in mandoc(1) by way of "Summer of Code". Highlights:
917: * fix "Sm" and "Bd" handling
918: * fix end-of-sentence handling for embedded sentences
919: * polish man(7) documentation
920: * document all mdoc(7) macros
921: * polish mandoc(1) -Tps output
922: * lots of internal clean-ups in character escapes
923: * un-break literal contexts in man(7) documents
924: * improve -Thtml output for -man
925: * add mandoc(1) -Tpdf support
926:
927: Changes in version 1.10.4, released on July 12, 2010
928:
929: * Lots of features developed during both "Summer of Code" and the
930: OpenBSD c2k10 hackathon:
931: * minimal "ds" roff(7) symbols are supported
932: * beautified SYNOPSIS section output
933: * acceptance of scope-block breakage in mdoc(7)
934: * clarify error message status
935: * many minor bug-fixes and formatting issues resolved
1.3 schwarze 936: * see also changes in 1.10.3
937:
938: Changes in version 1.10.3, June 29, 2010, NOT released
939:
940: * variable font-width and paper-size support in mandoc(1) -Tps output
941: * "Bk" mdoc(7) support
1.1 schwarze 942:
943: Changes in version 1.10.2, released on June 19, 2010
944:
945: * Small release featuring text-decoration in -Tps output,
946: a few minor relaxations of errors, and some optimisations.
947:
948: Changes in version 1.10.1, released on June 7, 2010
949:
950: * This primarily focusses on the "Bl" and "It" macros described in
951: mdoc(7). Multi-line column support is now fully compatible with groff,
952: as are implicit list entries for columns.
953: * Removed manuals(7) in favour of http://manpages.bsd.lv.
954: * The way we handle the SYNOPSIS section (see the SYNOPSIS documentation
955: in MANUAL STRUCTURE) has also been considerably simplified compared
956: to groff's method.
957: * Furthermore, the -Owidth=width output option has been added to -Tascii,
958: see mandoc(1).
959: * Lastly, initial PostScript output has been added with the -Tps option
960: to mandoc(1). It's brutally simple at the moment: fixed-font, with no
961: font decorations.
962:
963: Changes in version 1.10.0, released on May 29, 2010
964:
965: * Release consisting of the results from the m2k10 hackathon and up-merge
966: from OpenBSD. This requires a significant note of thanks to Ingo
967: Schwarze (OpenBSD) and Joerg Sonnenberger (NetBSD) for their hard work,
968: and again to Joerg for hosting m2k10. Highlights (mostly cribbed from
969: Ingo's m2k10 report) follow in no particular order:
970: * a libroff preprocessor in front of libmdoc and libman stripping out
971: roff(7) instructions;
972: * end-of-sentence (EOS) detection in free-form and macro lines;
973: * correct handling of tab-separated columnar lists in mdoc(7);
974: * improved main calling routines to optionally use mmap(3) for better
975: performance;
976: * cleaned up exiting when invoked as -Tlint or over multiple files
977: with -fign-errors;
978: * error and warning message handling re-written to be unified for
979: libroff, libmdoc, and libman;
980: * handling of badly-nested explicit-scoped macros;
981: * improved free-form text parsing in libman and libmdoc;
982: * significant GNU troff compatibility improvements in -Tascii,
983: largely in terms of spacing;
984: * a regression framework for making sure the many fragilities of GNU
985: troff aren't trampled in subsequent work;
986: * support for -Tascii breaking at hyphens encountered in free-form text;
987: * and many more minor fixes and improvements
988:
989: Changes in version 1.9.25, released on May 13, 2010
990:
991: * Fixed handling of "\*(Ba" escape.
992: * Backed out -fno-ign-chars (pointless complexity).
993: * Fixed erroneous breaking of literal lines.
994: * Fixed SYNOPSIS breaking lines before non-initial macros.
995: * Changed default section ordering.
996: * Most importantly, the framework for end-of-sentence double-spacing is
997: in place, now implemented for the "end-of-sentence, end-of-line" rule.
998: * This is a stable roll-back point before the mandoc hackathon in Rostock!
999:
1000: Changes in version 1.9.24, released on May 9, 2010
1001:
1002: * Rolled back break-at-hyphen.
1003: * -DUGLY is now the default (no feature splits!).
1004: * Free-form text is not de-chunked any more: lines are passed
1005: whole-sale into the front-end, including whitespace.
1006: * Added mailing lists.
1007:
1008: Changes in version 1.9.23, released on April 7, 2010
1009:
1010: * mdocml has been linked to the OpenBSD build.
1011: * This version incorporates many small changes, mostly from patches
1012: by OpenBSD, allowing crufty manuals to slip by with warnings instead
1013: of erroring-out.
1014: * Some subtle semantic issues, such as punctuation scope, have also
1015: been fixed.
1016: * Lastly, some issues with -Thtml have been fixed, which prompted an
1017: update to the online manual pages style layout.
1018:
1019: Changes in version 1.9.22, released on March 31, 2010
1020:
1021: * Adjusted merge of the significant work by Ingo Schwarze
1022: in getting "Xo" blocks (block full implicit, e.g., "It"
1023: for non-columnar lists) to work properly. This isn't
1024: enabled by default: you must specify -DUGLY as a compiler
1025: flag (see the Makefile for details).
1026:
1027: Changes in version 1.9.20, released on March 30, 2010
1028:
1029: * More efforts to get roff instructions in man(7) documents under
1030: control. Note that roff instructions embedded in line-scoped,
1031: next-line macros (e.g. "B") are not supported.
1032: * Leading punctuation for mdoc(7) macros, such as "Fl ( ( a",
1033: are now correctly handled.
1034:
1035: Changes in version 1.9.18, released on March 27, 2010
1036:
1037: * Many fixes (largely pertaining to scope)
1038: and improvements (e.g., handling of apostrophe-control macros,
1039: which fixes the strange "BR" seen in some macro output)
1040: to handling roff instructions in man(7) documents.
1041:
1042: Changes in version 1.9.17, released on March 25, 2010
1043:
1044: * Accept perlpod(1) standard preamble.
1045: * Also accept (and discard) "de", "dei", "am", "ami", and "ig"
1046: roff macro blocks.
1047:
1048: Changes in version 1.9.16, released on March 22, 2010
1049:
1050: * Inspired by patches and bug reports by Ingo Schwarze,
1051: allowed man(7) to accept non-printing elements to be nested
1052: within next-line scopes, such as "br" within "B" or "TH",
1053: which is valid roff.
1054: * Longsoon architecture also noted and Makefile cleaned up.
1055:
1056: Changes in version 1.9.15, released on February 18, 2010
1057:
1058: * Moved to our new BSD.lv home.
1059: * XHTML is now an acceptable output mode for mandoc(1);
1060: * "Xr" made more compatible with groff;
1061: * "Vt" fixed when invoked in SYNOPSIS;
1062: * "\\" escape removed;
1063: * end-of-line white-space detected for all lines;
1064: * subtle bug fixed in list display for some modes;
1065: * compatibility layer checked in for compilation in diverse
1066: UNIX systems;
1067: * and column lengths handled correctly.
