Readium / Description

EPUB Reader for Chrome
Readium for Chrome is the Chrome browser extension configuration of ReadiumJS, an open source
reading system and JavaScript library for displaying EPUB® publications in web browsers. ReadiumJS is a
project of the Readium Foundation. EPUB is a widely adopted portable document format based on Web
standards such as HTML5, CSS, JavaScript, and SVG. EPUB is a registered trademark of the International
Digital Publishing Forum (IDPF).

Improvements and Enhancements in this Release
This release, 2.26.0, includes some minor fixes to page-refresh handling and improvements to low-level (CFI) navigation. However, the major change is not in this release, but in the Google Chrome browser itself (over which we have no control). With the release of Google Chrome 57 on March 9, Google “fixed” a security hole for iFrames (which are used in the Readium Chrome app. The result is that any inline-script in EPUB content causes the browser to throw an exception and not execute the script. The result to the user is that almost all JavaScript-based interactivity has ceased to work.
It is possible to write one’s JavaScript so that it does not trigger this exception but virtually all the interactivity in existing EPUBs and EPUBs generated by tools such as InDesign will fail due to this change in the browser. Again, this is NOT in the Readium Chrome app, but in the browser. As a result, there is nothing we, Readium, can do to fix this for existing EPUBs.
We are continuing to look for other options, but at this time it would appear that the only viable solution is a significant rewrite of the app to not use the Chrome application framework at all.
