The page on ONIX metadata now includes descriptions for the new values 25 through 29 and 93.

May 4, 2022 — Updated EPUB 3 specification links

In anticipation of EPUB 3.3 moving to a W3C Candidate Recommendation in the next couple of weeks, all links to older versions of EPUB 3 have been updated. The changes in the EPUB 3.3 specification do not affect the guidance in this site, but the new specification is easier to read and includes many clarifications.

April 30, 2022 — Redesigned pages

The topic pages have been redesigned to make them easier to read. The table of contents for each page is now available in a sidebar rather than compressed on a single line beneath the page title. The breadcrumb has been replaced by a category heading above each title. Clicking on the category will take you to a list of all topics for that category. Finally, a "Topics" link is now available in the main menu bar to return to the home page. Previously, you had to click the site title to return.

The accessibilityFeature page now includes the newly added "ARIA" value for indicating that a publication makes use of ARIA document structure and landmark roles to improve its structure and navigation.
