Release Notes - Summary

Here is a list of notable changes since the previous release:

  • Upgraded to DAISY Ace v1.3.0 release which is based on the DAISY fork of Deque Axe version 4.7.2 (see daisy/axe-core#11 ). This brings many fixes and alignments with the latest ARIA specifications.
  • Support for the EPUB Accessibility 1.1 specification "Conformance and Discoverability Requirements for EPUB publications" (W3C Recommendation dated 25 May 2023).
  • Updated DAISY Knowledge Base (local documentation browser)
  • Fixed accessibility metadata conformsTo which can be a string label in spec 1.1, but was only URL (IDPF WCAG) in spec 1.0 => link vs. meta handling is now updated
  • Fixed ordering rule/check in page list.
  • accessibilitySummary metadata is now recommended (SHOULD), not required (MUST). The impact/severity is downgraded from serious to moderate.
  • conformsTo metadata is a link in the a11y spec. 1.0 (IDPF WCAG URLs), but can be string label in 1.1
  • metadata "refines" is not filtered out for a11y properties that are globally hoisted to the level of the publication (unlike say, media overlays duration for individual spine items, or dc:title subtitle title-type refine)
  • Updated Electron to latest version which includes a recent Chromium web browser engine revision (same as Ace "core" / command line, which now runs by default on Electron in order to ensure consistent reports with the GUI app).
