This version 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. If you find something you think needs to change in the TEI Guidelines, schemas, tools, or website, please submit a feature request or bug issue at https://github.com/TEIC/TEI/issues for consideration. Lists of closed bugs and closed feature requests are available on the site.

Some of the more noticeable changes in this release include: Probably the most significant change in this release involves no real change to the Guidelines themselves, but a big shift in the way their development and publication proceeds. The TEI Guidlines are now hosted on Github. This has entailed significant changes to our testing and release processes and will, we hope, make it both easier for us to develop the Guidelines and easier for the TEI community to engage with their development. This change, and the associated work has unfortunately meant a delay in the release of two major new features: the Pure ODD content model revision and TEI Simple, which depends on Pure ODD. We plan to release these features before the end of 2015. A new element has been added, xenoData, which provides encoders with a place to put non-TEI data they wish to embed in TEI documents. See . The critical apparatus elements lem and rdg may now contain structural elements, such as l, p, and div, allowing the creators of critical editions to describe textual variation at the structural level. See and . A new element to mark text secluded by an editor, secl was added, per . The event element is now allowed in org, per . The element hi is now permitted inside m, per . The deprecated status attribute was removed from att.identified. Added a new selector attribute on rendition, per . The deprecated degree attribute on precision has been removed. See and . And, of course, many typos were corrected.

In addition, improvements have been made to the XSL stylesheets (which provide processing of TEI ODD files for Roma and OxGarage as well as other TEI conversions). The Stylesheets are maintained separately from the Guidelines and are at https://github.com/TEIC/Stylesheets.
