This page is continuously updated to reflect significant changes to the DAISY Accessible Publishing Knowledge Base. For a complete list of changes, refer to the project's GitHub commit history.

Changes are listed from most recent to oldest.

June 2, 2023 — New layout for categories

To make it easier to find information, the list of categories is no longer buried in a drop-down menu. The list of categories now occupies the right-hand column of the site (this position may change depending on zoom level and device screen size).

The link to the glossary is now at the bottom of the page in the Site menu, as is the link to the page that lists all topics.

May 31, 2023 — New search box

It is no longer necessary to click through to a separate search page to query the knowledge base for information. A site search box is now available in the header of every page and is reachable from the page landmarks.

April 19, 2023 — WCAG parsing requirement

The forthcoming WCAG 2.2 revision will see success criterion 4.1.1 pass for all HTML and XML-based content as it no longer captures accessibility issues that aren't already covered by other success criteria. This change will also apply retroactively to WCAG 2.0 and 2.1.

The knowledge base now reflects this new guidance, advising that parsing errors that affect accessibility be reported under their more applicable success criteria. Refer to the WCAG explain for 4.1.1 for more information.

April 17, 2023 — Evaluation metadata

Now that the EPUB Accessibility 1.1 standard has reached Proposed Recommendation status in W3C, the guidance on reporting conformance now reflects the new identifiers used in that document.

Where the EPUB Accessibility 1.0 specification used idpf.org URLs to indicate conformance, the new standard uses easier to write and understand strings. The strings also adapt to new versions of WCAG as soon as they are released.

Publishers are encouraged to begin looking at migrating to the new standard as it should become a final recommendation in the next month.

March 24, 2023 — pageBreakMarkers and pageNavigation accessibility features

The page describing the schema.org accessibilityFeature property now includes information on the pageBreakMarkers and pageNavigation values.

The pageBreakMarkers value replaces printPageNumbers as more and more publications are being created with static page locations that are not tied to a print source. The pageNavigation value enables publishers to now identify when a publication includes a page list that allows users to access the page break locations.

March 24, 2023 — pageBreakSource property

Information about the new pageBreakSource property is now available on the page navigation page. This property is currently being incubated as a replacement for using the dc:source and page-source properties.

November 8, 2022 — WCAG 2.2 Explainers

The WCAG explainers now reflect changes made as WCAG 2.2 transitioned from a working draft to a candidate recommendation. These include adding pages for Focus Not Obscured (Minimum) and Focus Not Obscured (Enhanced) success criteria and consolidating Focus Appearance to a single success criterion.

The pages for Visual Indicators and Page Break Navigation now include warnings that they will be removed from the KB as they were dropped from WCAG 2.2.

September 7, 2022 — Poetry

A new page is now available discussing techniques for marking up lines of verse using the capabilities that HTML offers.
