Release 3.3.0 (code name: Johnny Rotten) of the TEI Guidelines introduces new features and resolves a number of issues raised by the TEI community. As always, the majority of these changes and corrections are a consequence of feature requests or bugs reported by the TEI community using the GitHub tracking system. A full list of the issues resolved in the course of this release cycle may be found under the 3.3.0 milestone.

Highlights of this release include: A new attribute class att.linguistic has been introduced.
