This release is a planned update for the products listed in the table
below. The latest version is always available through the product’s update
mechanism, from the enterprise FTP site, and
for some languages, from the Reader Download Center.
Improvements
Updating and patching
Unlike versions prior to 10.0, update and patch installers are now cumulative as follows: Planned updates are always cumulative to the last MSI and out of cycle updates are cumulative to the last planned update.
Note
Only the base release of Acrobat is an MSI and very few Reader updates will ever be an MSI, so in most cases quarterlies will be able to be applied to the base release.
Security
For more details about these and other security features, see the Application Security Guide.
- General vulnerability mitigation.
- Reader’s Protected Mode:
- Support for Citrix and Windows Terminal Services.
- Support for OLE: opening of PDF embedded in office documents and ability to embed PDF in office documents.
- iFilter compatibility: iFilter is used for search and indexing on Windows and enables keyword searching in a PDF from a Windows OS-based search. Prior to 10.1, iFilter did not work with Protected Mode enabled for Reader. To use iFilter on XP, the user must install Windows Desktop Search 4 (WDS4) which exists by default on new systems.
- Support for DirectX 8 was removed. Users who have been using DX8 as the preferred renderer for 3D and multimedia should upgrade their directX plugin to directX 9.
- Enhanced Security (Refer to the Preference Reference for configuration details):
- The definition of Win OS trusted sites has been extended to include Local Intranet zones as well as the current Trusted Sites zones. When Automatically trust sites from my Win OS security zones is enabled, both zones are trusted as if they were specified as Privileged Locations and are therefore exempt from Enhanced Security’s restrictions. The customer benefit is that it easily extends trust to numerous servers and subnets in trusted PDF workflows.
- Privileged Locations: Assigning trust to a folder is automatically recursive and also assigns trust to its subfolders.
Extended browser support
- IE 9 is fully supported.
- Viewing PDFs in Firefox 4 on Windows (not Mac)
- WebCapture with Firefox 4 and IE 9 on Win and Mac
Digital signatures
The following improvements have been added to 10.1:
- Acrobat/Reader 9.4.5 and Acrobat/Reader 10.1 will accept Identrust certificates with a SHA256 hash. Prior to these releases, certificates with OIDs under the Identrust arc enforced the use of SHA1.
- The Signature Properties dialog provides a clearer presentation of signing time and validation times:
- The Date fields on Date/Time and Summary tabs have been renamed to Signing Time. The field values always contains both the date and the signing time from the signer’s computer.
- The Date/Time and Summary tabs contain more validation time details. In addition to the signing time from the signer’s computer, the validation time also appears in some workflows. For example, when a timestamp is present (including post-signing timestamps), the Date/Time tab displays timestamp details such as if it is embedded, the timestamp authority name, and other information. Some of this additional information also appear in the Certificate Viewer.
- Prior to 10.1, OCSP responses without nextUpdate were never embedded in a signature. For 10.1 and later, OCSP responses are always embedded irrespective of the presence of nextUpdate; however, whether they are used for signature validation depends on certain conditions. This behavior is designed to support Acrobat’s long term validation feature and allows validating a signature with embedded responses that were valid at signing time. (Refer to Preference Reference.
- Portfolio signature status indicators: 10.1 implements a portfolio status indicator called a Signature Badge. A signature badge button appears in a signed PDF portfolio window’s taskbar except when the portfolio’s cover sheet is visible. Clicking the button displays the cover sheet and the expands the left-hand signature panel.
- Improved user experience for silent and automatic updates: On Windows 7, Vista, and Server 2008, 10.1 installs ARMsvc.exe as part of the Updater. The new service enables silent and automatic updates on machines where a user has configured the application for automatic updates. The service eliminates information dialogs prior to updates. In enterprise settings, IT can use DISABLE_ARM_SERVICE_INSTALL=1 to disable the ARM service.
SharePoint integration
Now, like Microsoft Office, Acrobat and Reader X will ask users if they want to check out a PDF when opening that PDF from within Reader/Acrobat from Windows Explorer or from the SharePoint browser interface. The check in/out process has been streamlined and enhanced along with digital signature workflows. For more details, go HERE.
Collaboration Workflows
Additional registry/plist preferences have been created to control the following:
bShowConnectDialog (Win) and ShowConnectDialog (Mac): Specifies whether the connect dialog in Shared Reviews appears. The setting maps to a checkbox entry under ‘Shared Review options’ in the ‘Reviewing’ pane in Preferences Dialog. By default, it is shown.bShowWelcomeDialog (Win) and ShowWelcomeDialog (Mac): Specifies whether the welcome dialog in Shared Reviews appears. The setting maps to a checkbox entry under ‘Shared Review options’ in the ‘Reviewing’ pane in Preferences Dialog. By default, it is shown.
Live mail support
Acrobat and Reader both support Live Mail on Windows 7.
