This is a new development branch. It is almost a total rewrite compared to 0.5.x, is much smaller, has a much simpler core, is easier to understand and learn, and has much cleaner code.
Class hrow was not compatiable with the HTML DTD, it was replaced with class hcell. Stylesheets in widgets can be now added and modified even after initilization, contary to the 0.5.0 implementation. Class html_tag now inherits a simpler class, xml_element. A new class, xml_comment, which, as it name suggests, renders comments ("<!-- -->" format) was added. HTML 3.2 fallback has been extended.
