Release Notes: The main issue was with HTML comments, which were very badly broken: any > character would terminate one, so commenting out elements did not work properly. Everything should now be correct. Everyone should update who possibly can. Additionally, &#Xnnnn (with capital X) now works, some debugging code was removed from PYXWriter, a Unicode BOM at the beginning of a document is skipped, and the new version of Saxon is supported as an XSLT processor. Documentation has been added on SAX features and properties specific to TagSoup.
Release Notes: A DOCTYPE declaration will be output if there is one in the input. The --ignorable switch was added to preserve whitespace in element content. The --output-encoding switch was added to specify output encoding. The default values for html/@version were removed. Various minor bugs were fixed.
Release Notes: All known bugs are fixed and all features considered appropriate have been added. This release is ready for full production use.
