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.

The Ace command line "package" is deployed to the official NPM registry under the "latest" release tag (the "next" release tag is used for intermediary test builds): https://www.npmjs.com/package/@daisy/ace/v/latest?activeTab=versions

Here is a copy of the changelog:

• Fixed crash 'confTo.startsWith is not a function' (was related to EPUB2/3 metadata parsing, handling of "conformsTo")
