Current Plan for the Next Release

Readium-1 (the original development projects for Readium, started in 2012) as now in maintenance mode. As a result, there are no plans at this time for a 0.32 release. However, if serious bugs (e.g. crash or data loss) are found then we may consider a new release.

Development efforts are now focused on “Readium-2”, which is now the mainstram development area for Readium. For more information, please see further documentation here and/or contact Ric Wright

Recent Releases

Readium 0.31

This release of Readium SDK and ReadiumJS (Chrome Application and Cloud Reader) comprises the final release of the Chrome Application and a number of changes to the ReadiumJS stack as part of the work transitioning to “Readium Web”.

Of significant importance are the following points:

  • This will be the final release of the Readium Chrome application. Google has warned that the Chrome framework (on which the app is based) is deprecated and will be disabled sometime in 2018. In addition, Google’s changes to their security rules (e.g. no inline scripts) has already partially crippled the application. Therefore we have made the decision to cease supporting and releasing the app. The final change to the app is that it puts up a modal dialog every time the library view is refreshed. The dialog states that the app is being deprecated and will be taken down before the end of 2018.
  • The Readium CloudReader will continue to be supported and bad bugs (i.e. crash and/or data loss) fixed, but no new features are planned.
  • The Readium SDK and the CloudReader (i.e. the ReadiumJS stack) will officially be put into maintenance mode. We will of course fix bad bugs (i.e. crash and/or data loss) but there is no plan to develop new features.

Improvements and Enhancements in this Release

Readium SDK

There are no significant changes to the SDK in this release.

Cloud Reader/Chrome App

The only real change to the Chrome Application in this release is the addition of the modal dialog which pops up every time the user refreshes the library view. The dialog states: “As Google has deprecated Chrome apps, this app is longer actively supported, and will no longer be updated after the 0.31, October 01, 2018 release. A list of other apps that are powered by Readium can be found at Readium.org” There are no significant external changes to the CloudReader per se in this release, but there are a fair number of restructuring and refactoring changes as part of the migration to the new architecture.

Readium 0.30

The Readium development community is pleased to announce the release of 0.30. This release was pushed to master and the Chrome store on 8 March 2018.

This release is primarily some minor updates:

  • A regression bug was fixed that caused the reader’s place in the book to be not restored properly when the book was re-opened.
  • The licenses in the SDK have been changed from GNU-Affero to BSD-3-Clause
  • Additional fixes and improvements to the Hypothes.is support in the Readium CloudReader
  • Updating the Android support in the SDK to the latest releases for Android tooling and the NDK
  • A number of minor bug fixes across the various modules (please see detailed release notes here

The tag for this release is 0.30 on GitHub.

Improvements and Enhancements in this Release

Readium SDK

There are only real change to the SDK is the change in the licensing from GNU Affero to BSD 3-clause. The Android tools have also been upgraded to the latest release.

Cloud Reader/Chrome App

The primary fix in this release is the correct restoring of the user’s place in the book between sessions. This was a regression introduced in release 0.29. There were several minor updates and fixes to the Hypothes.is support. In addition, MathJax now has AssistiveMML enabled and this has been integrated into the Readium codebases (both ReadiumJS and SDK). See a MathJax note about Assistive MML here and legacy accessibility support here.

Readium 0.29

The Readium development community is pleased to announce the release of 0.29. This release was pushed to master and the Chrome store on 22 December 2017.

This release is primarily some minor updates:

  • Additional fixes and improvements to the Hypothes.is support in the Readium CloudReader
  • Updating the Android support in the SDK to the latest releases for Android tooling and the NDK
  • A number of minor bug fixes across the various modules (please see detailed release notes here) The tag for this release is 0.29 on GitHub.

Improvements and Enhancements in this Release

SDK

Android tools and libraries (NDK) have been upgraded to the latest.

Shared Libraries (readium-shared-js and readium-cfi-js)

A number of improvements to navigation and layout.

Chrome App

This release, 2.29.0, includes no new user-visible features, but does include a large number of bug fixes related to navigation and page layout. These result in improved navigation and performance.

Readium Cloud Reader

The Readium CloudReader has now been enhanced to provide support for the Hypothes.is annotation and bookmarking client/server infrastructure. This release provides a number of minor bug fixes and enhancements to that support.

Note that the Hypothes.is support is ONLY available in the CloudReader version of ReadiumJS. It is NOT available in the Readium Chrome app. We regret this, but it is simply not feasible to implement that functionality within the Google Chrome app framework

The complete release notes are here.

Readium 0.28

This release is targeted for early fall 2017.

Candidate features include:

  • Merge many of the pending Pull Requests
  • More bug fixes (exact ones TBD)
  • Other features still TBD

Readium 0.27

Readium.org is pleased to announce that 0.27 version of Readium has been released. This release was pushed 12 June 2017.

This release of Readium SDK and ReadiumJS (Chrome Extension and Cloud Reader) is primarily a bug fix release..

The tag for this release is 0.27 on GitHub.

Improvements and Enhancements in this Release

Readium SDK

The only real change to the SDK in this release are some minor updates to the gradle build configuration.

Cloud Reader/Chrome App

There are two bug fixes in this release. The first, and most important, is to fix a regression bug in the handling of CFIs, particularly with respect to using CFIs with the table-of-contents in the CloudReader and the Chrome app. This bug resulted in inconsistent behaviour where clicking on a TOC entry would not go to the same (correct) location in the document. Instead, the destination would vary erratically. This is now fixed. The second bug occurred when some SVG was embedded in a reflowable document. In this case, the page-load spinner would be started on page load but would never stop. This is now fixed. The version of the MathJax library was bumped up to 2.7.1, which was primarily a build configuration upgrade. There were also a number of minor changes to build infrastructure (support for Yarn and Chai, etc.)

Readium 0.26

Readium.org is pleased to announce that 0.26 version of Readium has been released. This release was pushed 3 May 2017.

This release of Readium SDK and ReadiumJS (Chrome Extension and Cloud Reader) is a relatively significant release for the SDK as it comprises all the changes and improvements needed to integrate multiple DRM schemes, including Readium LCP.

The tag for this release is 0.26 on GitHub.

Improvements and Enhancements in this Release

Readium SDK

The primary change in the SDK is addition of support for Readium LCP and other DRM schemes. For more information about LCP, please see the FAQ here. To be clear, this release does not include the release of LCP itself but comprises the changes made to the SDK to enable app developers to integrate one or more DRMs, such as LCP or Sony’s URMS with applications based on Readium. These changes are primarily in the ContentModule and ContentFilter architecture. For developers not using those facilities the impact of these changes should be small or non-existent. However, as part of these changes there were also non-trivial changes to the Gradle-based build processes for Android. This includes a requirement to be using Android Studio (as Eclipse is officially deprecated by Google). Developers should be using the latest build of Android Studio, which is 2.3.1 at the time of this release. This release is also compatible with the “experimental Gradle plugin” which enables debugging into C++ in addition to Java.

Cloud Reader/Chrome App

There are no new features in the Chrome App or the Cloud Reader. However, the release of Google Chrome v. 57 on March 9 “fixed” a previous security hole in its browser extensions framework. The result is that nline-script (JavaScript embedded in an EPUB page) will no longer function in the Readium Chrome app, due to tighter Content Security Policy checks. Instead, an exception is thrown when an inline script attempts to execute. It is still possible to write scripts that will work in the EPUBs, but they have to be written in a specific way compatible with Chrome extensions’ CSP. For more information about the security protocol and how to write compliant JavaScript interactivity, see this article. An extensive discussion of the issue in the readium-js-viewer repository can be found here. The issue includes links to both invalid and valid EPUBs. For more information, please contact Ric Wright directly. Note! This security protocol does NOT affect the CloudReader, only the Chrome app. The CloudReader execution of inline JavaScript is not affected.

Readium 0.25

Readium.org is pleased to announce that 0.25 version of Readium has been released. This release was pushed 2 February 2017.

This release, 0.25, has one significant feature in the Chrome Extensions and number of minor improvements in both the Chrome App and the Cloud Reader - as well as a large number of bug fixes.

In the SDK, thep primary change in the SDK is addition of support for XCode 8. We also exposed more metadata via the JNI layer in the Java. Finally, we eliminated a potential security hole related to XML Entity declarations.

The new feature in the Chrome Extension is the capability and UI to allow users to change the font-face for a given document. In particular the OpenDyslexic font is now an option as well as a sans-serif font and a serif font. There is no capability for users to add new fonts. The CloudReader has the same feature to allow users to change fonts, plus a few more available (web) fonts.

In addition, there were a fair number of bug fixes.

The complete release notes can be found here.

Readium 0.24

Readium.org is pleased to announce that 0.24 version of Readium has been released. This release was pushed 16 August 2016.

This release, 0.24, is a new release that has one significant feature in the Chrome Extensions and number of minor improvements in both the Chrome Extension and Cloud Reader - as well as a large number of bug fixes.

In the SDK, there were a number of minor bug fixes, plus the removal of some obsolete libraries (OpenSSL for Android and Boos).

The new feature in the Chrome Extension (which is NOT in the Cloud Reader) is the support for importing more than one file at a time. Multiple files can be added via drag and drop onto the library pane or via the normal “Add File” dialog. Once the import has started, the user CAN cancel the import process but the file being imported when the cancel button is pressed will still be imported but subsequent queued files will not be imported.

In addition, there were two regressions in the previous releases:

  • An experimental highlighting plugin was inadvertently included in the previous 2.23 build. While this is a nice feature, it is not yet complete - there’s no way to save the highlights. We are working on this but have no ETA when it will be available (volunteers are welcome).
  • Navigation using the TOC was not working correctly for TOC items that were not top level (i.e. sub-headers). This is now fixed in this release.

Readium - 0.23

Readium.org is pleased to announce that 0.23 version of Readium has been released. This release was pushed 10 June 2016.

This release, 0.23, is a new release that is has one major change and a number of minor improvements - as well as a large number of bug fixes, primarily affecting CFI/navigation. The major change is that we have switched Android build support from Eclipse (now deprecated) to Android Studio (currently 2.1). We also enabled (experimental) support for debugging from Java into C++ (see release notes for more info). Also, HTTP header caching has been enabled which can provide significant performance improvements for some resource-heavy EPUBs.

There are also some minor UX improvements to the Chrome Extensions. Finally, a subset of OPDS support was added to the CloudReader (it was experimental before). You can see a demonstration of it here.
