Version 8.3.0 (2008-11-29)

   Additions and changes
     * [1]AsciiDoc new tables is a complete redesign of the tables syntax
       and generation. The new syntax and features are a huge improvement
       over the old tables. The old tables syntax has been deprecated but
       is currently still processed.
     * [2]Lists can now be styled like other block elements. This allows a
       single list syntax for glossary, qanda (Question and Answer) and
       bibliography lists instead of having to remember a different syntax
       for each type.
     * Inline passthroughs macros have been improved and block passthrough
       macros added. Attribute substitution can be optionally specified
       when the macro is called.
     * The passthrough block has a fully transparent passthrough delimited
       block block style called pass.
     * The asciimath and latexmath [3]passthrough macros along with
       asciimath and latexmath [4]passthrough blocks provide a (backend
       dependent) mechanism for rendering mathematical formulas. There are
       [5]LaTeX Math, [6]AsciiMathML and [7]LaTeXMathML examples on the
       AsciiDoc website.
     * Reimplemented and cleaned up filter processing based on a patch
       submitted by Kelly Anderson. Uses the newer subprocess module
       instead of the deprecated popen2 module. Now works in Win32 command
       shell.
     * Addition FAQs, more documentation updates.
     * Arbitrary HTML/XML entities can be entered in AsciiDoc source.
     * Did away with the need for the shaded-literallayout.patch (thanks
       to Henrik Maier for this patch).
     * Implemented page break block macro.
     * Added line breaks and ruler processing instructions to DocBook
       outputs (thanks to Henrik Maier for this patch).
     * Added deg (degree) and wj (word joiner) entity attributes (thanks
       to Henrik Maier).
     * Tweaked DocBook indexterm2 macro to avoid white space preceding the
       term when used in table cells (thanks to Henrik Maier for this
       patch).
     * Title elements now process the options attribute like other block
       elements.
     * Added `single quoted' element.
     * Spaces on both sides of a -- em-dash are translated to thin space
       characters.
     * Improved detection and reporting of malformed attribute lists.
     * The list compact style is now a list option.
     * Added strong labeled list option which makes the labels bold (HTML
       outputs only).
     * Dropped unsupported linuxdoc backend.
     * Dropped deprecated xhtml-deprecated (version 6) backend.
     * Added breakable and unbreakable attribute options to tables to
       control table breaking across page boundaries (DocBook XSL/FO
       outputs). By and in collaboration with Henrik Maier.
     * Added pgwide attribute option to tables to table, block image,
       horizontal labeled lists. Specifies that the element should be
       rendered across the full text width of the page irrespective of the
       current indentation (DocBook XSL/FO outputs). Thanks to Henrik
       Maier for this patch.
     * Vim syntax highlighter: spaces before/after bullets no longer
       highlighted (which is ugly if using a theme that highlights with
       underlines). Thanks to Donald Chai for this patch.
     * Added a2x(1) --fop option.
     * Added a2x(1) --no-xmllint option.
     * Highlighted labelled list terms with the navy color in XHTML
       outputs.
     * Use w3m(1) as default a2x(1) text format generator (fallback to
       lynx(1)).
     * Changed callout formats in html4 and xhtml11 outputs to angle
       brackets to match source highlighter rendering.
     * Macros now inject user defined <optionname>-option attributes into
       markup.
     * Added IRC URLs to AsciiDoc inline macros.
     * Added depth attribute to include::[] system macro.
     * Added footnoteref inline macro.
     * Added stylesheet XHTML attribute to specify additional custom CSS
       stylesheet.
     * If a paragraph style is specified it will be added to the XHTML
       class attribute and DocBook role attribute.
     * Replacements can be set in a document using the reserved
       AttributeEntry name replacement.
     * The prefix for auto-generated section name IDs can be set with the
       idprefix attribute.

   Bug fixes
     * Escaped quote skipped over leading and trailing quote instead of
       just the leading quote.
     * Fixed bug that was causing false negative safe mode warnings (patch
       submitted by Julien Palmas).
     * Placed priority of AttributeEntry, AttributeList and BlockTitle
       above Title. This ensures an AttributeEntry, AttributeList or
       BlockTitle followed by a same length leading ListingBlock delimiter
       is not mistaken for a two-line title.
     * Vim syntax highlighter: fixed multi-line quoted text.
     * Contstrained quote termination after non-space character enforced.
     * Vim syntax highlighter: unterminated quoted text is no longer
       highlighted.
     * Vim syntax highlighter: passthroughs now exactly match AsciiDoc
       semantics.
     * Vim syntax highlighter: escaped quoted text, attribute references
       and inline macros are not highlighted.
     * Vim syntax highlighter: TODO's highlighted in CommentBlocks (thanks
       to Scott Wall); non-greedy $$...$$.
     * Vim syntax highlighter: Comment lines mistaken for vertical list
       labels (thanks to Scott Wall).
     * Vim syntax highlighter: Single unmatched $$ mistakenly highlighted
       remaining text (patch contributed by Scott Wall).
     * Callouts now work in source highlighted listing generated by
       dblatex.
     * Fixed exception that occured if undefined attribute was present in
       filter command.
     * AttributeList block can now follow a paragraph without intervening
       blank line.
     * The include macro tabsize attribute is no longer propagated to
       nested includes.

   Omissions
   The following features were implemented but then but removed from this
   release:
     * pi, cdata and comment passthrough macros and passthrough block
       styles (creeping featurism, use pass macros instead).
     * Generic tag inline macro (creeping featurism, use pass macros
       instead).

  1.1. Compatibility issues

   Version 8.3.0 has a number of backward incompatibilities with respect
   to the previous 8.2.7 release:
     * The old table syntax is still processed but a DEPRECATED warning is
       issued.
     * Entity references have to be escaped with a backslash.
     * You have to explicitly precede horizontal style labeled lists with
       the [horizontal] style attribute -- by default all labeled lists
       are rendered vertically.
     * The list compact style has been dropped and is now a list option
       (use options="compact" in attribute lists).
     * AsciiDoc version 6 sytnax no longer supported.
     * Linuxdoc been removed from the distribution.
     * The unsupported experimental latex backend has not been tested on
       this release.
     * The introduction of single-quote quoting requires that double-quote
       quoting is escaped with two backslashes.
