Adobe® Digital Editions 1.7.1 Release Notes

Adobe Systems 7 April 2009

This document accompanies the release of Digital Editions 1.7.1. This release consists essentially of the removal of one now-obsolete feature and some bug fixes.

The feature that has been removed is that Digital Editions no longer supports fulfillment from Adobe Content Server 3-powered sites. Adobe Content Server 3 is now obsolete, having been replaced by Adobe Content Server 4.

As of March 30, 2009 Adobe de-activated the support in the Adobe Content Server 3 activation server such that no new instances of Acrobat or Reader could be activated. Existing instances of Acrobat and Reader that had already been activated will continue to work and can still fulfill content from any website still providing Adobe Content Server 3 content.

With this release, Digital Editions will no longer fulfill content from sites powered by Adobe Content Server 3 (though few are left at this time). Digital Editions is still able to migrate existing Adobe Content Server 3-licensed eBooks to the new Adobe Content Server 4 license format. Such migration will be supported until mid-December 2009. After that no more migrations will be possible.

1. Users with lowered privileges (non-administrators) on Windows Vista machines may encounter problems when fulfilling content with Digital Editions. This is due to the enhanced security features found in Vista. The workaround is

Note: UAC is a Windows security feature. You should only disable this if you are sure your system is otherwise secure.

2. On Windows, if and only if the user installed Digital Editions 1.7 (the previous release to this one) in a non-default location, the 1.7.1 installer will not remove the previous version (i.e. 1.7). If the user accepted the default location of Digital Editions, then the 1.7.1 installer will automatically remove the older version. But if the previous install wasn't to the default location, then the user will have to manually delete the older version.

3. Users cannot fulfill eBooks successfully using the Opera browser. Instead of passing the ACSM file to Digital Editions, Opera by default opens the file. This can be avoided by the following:

4. Portuguese support. Digital Editions 1.7 supports Brazilian Portuguese, not European Portuguese. The differences are not large, but Adobe is aware they are not the same. We will support both in a future release but in the current release we have mapped European Portuguese locales into Brazilian Portuguese so the correct language is displayed. However, there are some cases where the user may have to make minor settings at the OS level to get the right result.

If customers find other issues between the two variants of Portuguese, please let us know.

5. Safari has been designed to protect users from unsafe files and plugins. While files known by Safari to be safer are automatically opened, the acsm files that Digital Editions uses are not known by Safari, which will download the files but not launch them. To override this you must specifically tell Safari that acsm files are "safe" by creating/modifying your Mac's com.apple.DownloadAssessment.plist file. For a discussion of this well known Safari issue see the following blog posts:

Users may encounter similar issues with other browsers, depending on their security settings.

6. Installing Digital Editions 1.7.1 on a Mac does NOT uninstall the old version. In order to uninstall the old version, you must uninstall manually. This is described in "Installing Digital Editions 1.7 on Mac OS does not uninstall Digital Editions 1.6" (TechNote kb408375).

7. Digital Editions does not at this time, support JPEG2000. It does support JPEG, GIF and PNG images. Support for JPEG2000 will be added in a subsequent release.

8. Sometimes, on Macintosh Intel computers, when the "End User License Agreement" (EULA) is presented to the user, it does not have the focus. The EULA is even sometimes hidden behind the browser. This latter behavior has also been reported occasionally for Vista. The only workaround is to manually bring the dialog to the front (if hidden) and click on the window of the dialog.
