Changes and new features introduced in Version 3.05 Bug fixes ANSI C (getting very very close...)

Ability to set simple document options in the command line Horizontal galleys (for expert users) Drop capitals (large capitals in top left corner of paragraph) Optimal body text breaking (makes large in-line displays more practical) More flexible control of the format of chapter, section etc. headings Option for starting chapters etc. on any, odd, or even pages Command line option -S for safe execution (prohibits calls to system()) Symbols for up to three independent indexes at the end of each document References work now when the citation point is after the reference list Placement of objects at arbitrary points on the page Reference lists may be before or after appendices Choice of nine locations for figures and tables (page top, foot, etc.) Numbering of footnotes works properly in all unusual cases now Database index files created afresh automatically if system has stat() Choice of rules for spaces between words (like Lout, troff, or TeX) Spacing in equations (both eq and teq) further improved Kerning of accented characters deduced from corresponding unaccented ones @NotRevealed symbol (for expert users) Another, hopefully better attempt made at Latin-2 formatting Changes and new features introduced in Version 3.08 Bug fixes Changes and new features introduced in Version 3.09 Bug fixes French hyphenation foll_or_prec works in all cases now, not just galleys (for expert users) @Enclose symbol (for expert users) Multi-page figures and tables can be boxed (revised @Format option) Optimal paragraph breaker has been tuned to discourage widow words, and to hyphenate more paragraphs but use fewer hyphens when it does More consistent set of setup files since all now derived from one master Setup files "doc" and "report" now work with plain text output Unpaginated (continuous) plain text output @FirstChapterNumber, @FirstSectionNumber etc. options in setup file Alternative error message format (filename:linenum:colnum: ...)

See User's Guide for details. (2) Setup file arrangements have changed. You now need to have one @SysInclude line for each package you use. For example, Previous versions Version 3.13 --------------------------------------------- @SysInclude { eq } @SysInclude { eq } @SysInclude { ddoc } @SysInclude { diag } @SysInclude { doc } Import clauses in mydefs files also have to change: Previous versions Version 3.13 --------------------------------------------- import @DocumentLayout import @BasicSetup import @CPrint import @CPSetup import @DiagramPrint import @DiagSetup Sorry for the inconvenience, but the old system was inconsistent and was tending towards an unsustainable combinatorial explosion of setup files. No changes *within* documents are needed, and these new arrangements do not affect the content of the packages. The user's guide documents it all. Changes and new features introduced in Version 3.14 [released March 1999] Bug fixes "lout -PDF" now available as alternative to "lout -Z" Cross referencing list items yields just the raw item number now Changes and new features introduced in Version 3.15 [May 1999] Bug fixes @FootNoteFormat option for controlling format of footnotes @TheoremFormat option for controlling format of theorems (etc.) @ListOuterGap setup file option for space before and after lists Standardized and improved "slides" package, incl. new setup file options (NB please send me @Word&&lecture and @Word&&overhead in your language) Faster database reading (uses more memory though); prevent with -M @DoubleLine symbol in diagrams for drawing a double line -l and -L flags for selecting collation order (see lout -u) Changes and new features introduced in Version 3.16 [28 May 1999] Bug fixes Optimal paragraph breaking weights adjusted yet again (sigh) Changes and new features introduced in Version 3.17 [13 September 1999] Bug fixes @AtEnd option for @Book and @Report (unnumbered back cover page) @Abbreviations symbol in books (like @Introduction but for abbreviations) @Euro symbol added for getting a European Currency symbol Document OBJECT struct declaration in externs.h (for gurus only) Changes and new features introduced in Version 3.18 [26 February 2000] Bug fixes (more than usual, somehow) New @CurrYUnit and @CurrZUnit symbols (expert users) @Diag enhancement: node types, similar to row types in @Tbl @Diag enhancement: new features for drawing syntax diagrams Portuguese (thanks to Jose Roberto B. de A. Monteiro) Slight change to @Tbl spec (affects aligned columns) Replaced c2lout with prg2lout (computer program formatting) @Outline symbol for printing words in outline rather than filled A few extra @Eq symbols: filledcircle, small, trieq Changes and new features introduced in Version 3.19 [9 March 2000] Bug fixes Four @HeaderComponent symbols for running headers (expert users) Running headers in multi-page tables Running headers in indexes Two extra @Eq symbols: triangleup, triangledown Changes and new features introduced in Version 3.20 [8 April 2000] Bug fixes (including the internal error that was dumping core recently) Multi-line style changes (@I, @Colour etc.) now work in lines @Break mode @Perl symbol for Perl programming language formatting (includes Pod) Changes and new features introduced in Version 3.21 [10 May 2000] Bug fixes (including an old problem of bits lost from programs in tables) Refinements to @Perl symbol for Perl programming language formatting Program texts can now be formatted with line numbers added -V now tells about PDF compression and whether debug output is available "Page body margins" for indenting of page body wrt headers and footers Margin notes code updated to work as desired with the new page body margins @PageEnclose symbol generalizes @PageBox (enclose each page in anything) Robustness wrt Linux strcoll() improved (tab characters no longer compared) "Abstract" word in tech reports now centred again by default Lout now builds composite characters - see Expert's Guide, under @Font *** IMPORTANT: ONE CHANGE THAT IS NOT UPWARDLY COMPATIBLE *** If you are using your own setup file, then it is likely to contain the line "@SysInclude { fontdefs }". There is no longer a fontdefs file, there is now a fontdefs database, so you need to replace this line with "@SysDatabase @FontDef { fontdefs }". Changes and new features introduced in Version 3.22 [3 June 2000] Bug fixes More setup file options for controlling the appearance of reports Makefile now explicitly explains how to compile with debugging on/off Added quotesinglebase, quotedblbase, ellipsis to LtLatin2.LCM file Object-oriented back end (of interest to implementors only) Chapters without page breaks option (see @ChapterStartPages, User's Guide) Font includes all in page setups now (of interest to implementors only) Changes and new features introduced in Version 3.23 [24 June 2000] Bug fixes, including Uwe's fix of the nasty bug reported by Matej Cepl, and my fix of a table running headers bug reported by Matthew Neumann. Cross links (see User's Guide, Cross References and Links section) New symbols for expert users: @LinkSource and @LinkDest @Python symbol for typesetting Python programs using prg2lout. Changes and new features introduced in Version 3.24 [8 October 2000] Bug fixes, including a new and better fix for table running headers bugs Things that ought to be done but haven't been done yet Various improvements/bug fixes for PDF output Review Uwe's proposal for moving word row marks to the baseline Jeff Kingston 8 October 2000
