Readium (JS) release Notes

(Chrome extension / cloud reader)

0.17

Improvements and Enhancements in this Release

This release, 0.17, is a new release that is primarily bug fixes for the Android SDK and the Chrome Extension with a number of minor fixes elsewhere.

Note: The previous release, 0.16, was released as “1.0”. This label of "1.0" was in many ways simply window-dressing, representing Readium’s declaration that the SDK and associated Launchers were now EPUB 3.0 compliant and ready for prime-time. However, it was clear that the Android code in the SDK wasn’t quite complete, so it became the focus of this release. Further, with this release, we have returned to labeling the release by the “sprint” or phase of the work, in this case the 17th sprint of Readium. Similarly, the Readium Chrome Extension (expected to reach the Chrome Store in early April 2015 to coincide with the release of Chrome 42.0) will be labeled 2.17.x.

Note: Numbers below refer to issues and/or pull request. Links will take you to the issue or PR.

Chrome Extension

• Fix for a bug where very large resources (e.g. >100 MB) WITHIN an EPUB would cause the load into the library to fail (280)
• Fix for the case where a failed load into the library would throw an exception and this would cause the user’s entire library to be erased (!) (280)
• Minor fixes to some error messages (294)

Shared

• Switched to using a new jQuery library (1.11.2), which uses a version-free naming convention (156) Fix a number of minor bugs (287, 269, 284, 271, 40)
