Release Notes

ACS Version 6.5 - October 2015

What is new in this release:

This release enables seamless fulfillment of books across devices. With this new feature, when a consumer fulfills a book on one device, the book will be automatically downloaded to all the other devices that belong to this consumer (activated using the same user ID).

ACS Version 6.0 - September 2014

What is new in this release:

This release includes new features that enable distributors to avail variable pricing based on Geo, MRP, and subscription. Now, ACS also supports bulk fulfillment and school models on multiple devices for distribution across organizations. For detailed information on new features, see ContentServer_Whats_new.pdf in the release folder.

ACS Version 5.0 - Jan. 2014

What is new in this release:

  • DRM Hardening - Digital Rights Management scheme to protect ePub and PDF files from unauthorized viewing is now made more secure. You can configure ACS to harden the DRM for additional security.
  • PDF search Performance Improvement - Performance improvements to PDF text search when the text is not present in the specified range.

ACS Version 4.2 - Dec. 2012

The important new features in this release are:

  • Special handling for the encryption during packaging of audio and video content within ePub3 documents. When viewing or playing back this content, a viewer can randomly access portions of the content for decryption; it is not necessary to decrypt the content sequentially from the start. This allows a viewer to support user scrolling through potentially very large content streams without having to process the entire stream, or buffering the unencrypted contents to temporary storage.
  • Tracking of the new ePub3-required dcterms:modified metadata element in the ACS 4.2 database schema. This element, together with dc:identifier, are specified in ePub3 to form a unique identifier for the document.

You can update previous versions of ACS to version 4.2.

XMLSigningSerializer.php Code Update - June 2012

Datalogics has an updated version of XMLSigningSerializer.php that can properly generates the HMAC code for ACS web API request. For licensed customer, the updated php file can be found on our ftp site, under the ACS release folder. For evaluation customers, please contact to obtain an updated version.

ACS Version 4.1.2 - Sept. 2012

ACS 4.1.2 is a patch release to ACS 4.1.1. This release fixed the issues listed here. To update from ACS 4.1.1 is a simple process that requires only replacing the war files for each server component.

  • Under previous versions, certain PDF files would result in the error "com.adobe.internal.pdftoolkit.core.exceptions.PDFIOException: Invalid slice of Bytestream". ACS 4.1.2 includes a fix to allow these certain PDF files to be correctly packaged.
  • A fix for an issue with generating URLLink.acsm files with very long expiration periods. Previously, attempting to generate the URLLink.acsm file with an expiration period of greater than approximately 29 days would result in an already expired URLLink.acsm file.

ACS Version 4.1.1 - March 2011

ACS 4.1.1 is a patch release to ACS 4.1.0. This release fixed the issues listed here. To update from ACS 4.1.0 is a simple process that requires only replacing the war files for each server component.

  • This release includes a fix for a defect with the way fulfillments are recorded for an expiring loan. In the defect, if a loaned resource was re-fulfilled by the same user after the original loan had expired, the new loan would expire within just a few milliseconds. End users would see this problem if they then re-used this second fulfillment request. Using Adobe Digital Editions (ADE), this would result in the error message “No record for this loan is found on this machine, it may have been returned.”

ACS Version 4.1.0 - November 2010

ACS 4.1.0 is a major new release of Adobe Content Server. To update from ACS 4.0.x versions to ACS 4.1.x versions requires database migration. Major changes in this release include:

  • Support for fulfillment of files using a password-based encryption of the document key known as PassHash. Support for reading these files was added in the Reader Mobile SDK in the 9.1. Support for fulfillment was added in RMSDK 9.2. PassHash just changes the way the license is created, and does NOT require repackaging of any content.
  • Support for the element. This allows publishers to specify whether a document may be spoken via text-to-speech. If no permissions are specified during packaging, then this permission (along with all others) will be granted. Please see the User Guide for more info.
  • Data Paging. The results sets of a query can now be paged, to present a smaller dataset, which reduces both database load and transmission time for queries that would not result in large datasets.
  • The Admin Console now uses data paging to display results, making it usable with very large datasets.
