The bibliography styles"author-date" and "author-title" were renamed to "chicago-author-date" and "chicago-author-title"
Figure improvements
Figures now automatically detect their content and adapt their behavior. Figures containing tables, for instance, are automatically prefixed with "Table X" and have a separate counter
The figure's supplement (e.g. "Figure" or "Table") can now be customized
In addition, figures can now be completely customized because the show rule gives access to the automatically resolved kind, supplement, and counter
Bibliography improvements
The bibliography now also accepts multiple bibliography paths (as an array)
Parsing of BibLaTeX files is now more permissive (accepts non-numeric edition, pages, volumes, dates, and Jabref-style comments; fixed abbreviation parsing)
Labels and references can now include : and . except at the end
