This section describes the changes for the SGD 5.3 release.

1.2.1 New Version of the SGD Client for Mac OS X Platforms

This release includes an improved version of the SGD Client for Mac OS X client devices. The new version integrates well with the latest releases of Mac OS X.

1.2.2 Retirement of Windows Audio Sound Quality Attribute

The Windows Audio Sound Quality Attribute (--array-audio-quality) attribute has been retired in this release.

1.2.4 Changes to Configuration for VMS Applications

The required configuration to use SGD to access applications running on a VMS server has changed.

See Configuring VMS Applications in the Oracle Secure Global Desktop Administration Guide for details of the changes.

1.2.5 Changes to Attribute Names for Application Objects

The following attribute names have changed for application objects.

  • Keep Launch Connection Open (--keepopen) is now called Maintain Connection (--keepopen). This attribute specifies whether to maintain the connection to the application server.

  • Allow SSH Downgrade (--allowsshdowngrade) is now called Allow Unsecure X Connection (--allowunsecuressh). This attribute specifies whether to use an unsecured X11 connection to display the application, if X11 forwarding is not available.

In the Administration Console, these attributes are on the Launch tab for the application object. See Attributes Reference in the Oracle Secure Global Desktop Administration Guide for more details.

1.2.6 Disabling Automatic Installation Using Java Plug-in Software for Specific Browsers

A new context parameter, disallowjavauseragentmatch, enables Administrators to specify which browsers should not use Java Plug-in software to download and install the SGD Client automatically.

See Disabling Automatic Installation Using Java Plug-in Software for Specific Browsers in the Oracle Secure Global Desktop Administration Guide for more details of how to configure this parameter.

From this release, the SGD Client can be installed automatically using Java Web Start software. See Section 1.1.1, “Automatic Installation of the SGD Client Using Java Web Start”.
