This is a maintenance release of Ace, the Accessibility Checker for EPUB developed by the DAISY Consortium. Installation instructions and other documentation is available on Ace’s development web site.
Here is a copy of the changelog:
- Fix: aligned with the metadata properties defined in the W3C Community Report, notably missing schema accessibility features pageNavigation, printPageNumbers synonym pageBreakMarkers.
- Feature: added timeout configuration via environment variables, to override the Electron Axe runner processing logic:
ACE_TIMEOUT_INITIAL(default10000, which provides a 10s time allowance for the web window to load its document and contents) andACE_TIMEOUT_EXTENSION(default480000which provides a 480s / 8mn time allowance for the Axe checkers to execute inside the loaded document).
