- Deep code cleanup.

- Better table support

  - `Multicolumn` support (use of the attributes `namest`, `nameend`, `spanname`).

  - Better `frame`, `rowsep`, `colsep` attributes inheritance.

- Better bibliography support

  - `Bibliography` can be nested under any section.

  - `Biblioset` support.

  - Basic `bibliomixed` support.

- `Indexterm` `sortas` and `class` attributes support added.

- `Imagedata` `width`, `depth`, `scale` attributes support improved. In previous releases, `scale` was used instead of `width`. Now, you should use `width` or `scale` properly.

- `Programlisting` `linenumbering` attribute support added.

- Basic `glossary` support added.

- Better `reference` support. `Refnamediv` title is no more hard-coded (use of $refnamediv.title if not empty, or name automatically generated according to the lang).

- `Qandaset` improved. `Qandadiv` can be nested under any section.

- Better `xref` support. Now `xreflabel` and `endterm` work.

- The latex hyperref package is now automatically included in the dbk_core package. A customized LaTeX style package shouldn't include hyperref anymore.

- `Link` now works.

- `Trademark` `class` attribute managed (except class='service').

- A `keyword` is not displayed but is inserted in the index entries.

- Some bug fixes.
