Release 11 SP2 Build 11.2.053 3
· Improved VoIP (UDP Audio) - This feature allows audio to be sent across UDP
instead of TCP. UDP Audio only supports medium-quality audio. Medium-quality
audio can be specified by adding AudioBandwidthLimit=1 in the [WFClient]
section of the wfclient.ini. If UDP is enabled but the quality is not medium, audio
transmission will revert to TCP. Audio data is not encrypted over a UDP
connection, so UDP Audio is not available with encrypted sessions (using SSL or
ICA Encryption) and audio transmission will revert to TCP. UDP Audio is disabled
by default in the Receiver. Requirements: XenDesktop 7.
· Graphics/Audio Multithreading - By default, Receiver for Linux 13.0 uses a
thread for Thinwire graphics and another for client audio input and output. This
reduces the load on the main thread, making other virtual channel data more
likely to be processed in a timely manner.
· Self-service GUI and SDK - Self-service GUI is not supported in this release.
Connection Manager is used instead of a self-service GUI.
The following are some identified constraints and limitations for the Citrix 13.0
feature:
• PAM implementation for storefront connection is not supported.
• Smart card authentication is not supported in Receiver for Linux deployments
using StoreFront.
• Smart card is supported only for the server option in the Connection Manager.
• Desktop Appliance mode works only for PNServer.
• Single sign-on with Smartcard is not supported.
• Only https is supported for storefront connections.
• It is recommended to use FQDN for all connections.
• SP1 to SP2 upgrade has following limitations:
1 - In SP2 while creating connections for HTTPS, the user must use a FQDN
instead of an IP address. However, a user could use IP for http. This limitations is
because of CITRIX 13 where it is mandatory to use fqdn for https connections.
2 - Cannot launch PN published apps after an upgrade from SP1 to SP2. Only
server connections can be launched as it uses wfica. PN published apps could
not be launched as some mandatory parameters required in SP2 are missing.
One of the mandatory parameters for Citrix 13 storebrowse to work is resource
id which is unique and is received after enumeration. For this, user credentials
are required.
NOTE: In SP1 it was not mandatory to provide user credentials for published
applications. If such connections are created in SP1 and then upgraded to SP2,
enumeration would fail. Therefore, only those Published application connections
created in SP1 with user credentials can be launched in SP2 as well.
