Better xml output (pretty layout). Check out the generated XML.
Regression testing facility: to make sure your document will always be compatible
(full backward compatibility) regardless of changes to QuickBook.
Code cleanup and refactoring.
Allow phrase markup in the doc-info.
Preformatted code blocks via ``code`` (double ticks) allows code in tables
and lists, for example.
Quickbook versioning; allows full backward compatibility. You have to add
[quickbook 1.3] to the doc-info header to enable the new features. Without
this, QuickBook will assume that the document is a pre-1.3 document.
Better (intuitive) paragraph termination. Some markups may terminate a paragraph.
Fully qualified section and headers. Subsection names are concatenated to
the ID to avoid clashing. Example: doc_name.sect_name.sub_sect_name.sub_sub_sect_name
Better and whitespace handling in code snippets.
[xinclude] fixes up the relative path to the target XML file when input_directory
is not the same as the output_directory.
Allow untitled tables.
Allow phrase markups in section titles.
Allow escaping back to QuickBook from code, code blocks and inline code.
Footnotes, with the [footnote This is the footnote] syntax.
Post-processor bug fix for escaped XML code that it does not recognize.
