Support for iPhone X

Citrix Receiver for iOS supports the iPhone X.

What’s new in 7.5

Enhancement to adaptive transport

In earlier releases, when HDXoverUDP in the ICA file is set to Preferred, data transport over EDT is used when possible, with fallback to TCP.

Starting with this release and with session reliability enabled, EDT and TCP are attempted in parallel during initial connection, and during session reliability reconnection. This enhancement reduces connection times when EDT is preferred but TCP needs to be used as is the case when the required underlying UDP transport is unavailable.

By default, after fallback to TCP, adaptive transport continues to seek EDT every five minutes.

New signing certificate

Citrix is changing the signing certificate for Citrix Receiver 7.5 for iOS. This change ensures all Citrix iOS apps are consolidated under one signing certificate and allows improved inter-application communication between all Citrix iOS apps. After upgrading to Citrix Receiver 7.5 for iOS, devices configured to use client certificates or an RSA software token to log on to Citrix Receiver will need to re-import client certificates and RSA software tokens before they can log on to Citrix Receiver for iOS. Devices configured for other authentication methods will not be affected by this change. New installations of Citrix Receiver 7.5 for iOS are also not affected by the signing certificate change. For more information, see Knowledge Center article CTX231419.

Joint Server Certificate Validation policy

Citrix Receiver 7.5 for iOS introduces a new, stricter validation policy for server certificates, which might affect session launches. A Strict Certificate Validation setting has also been added in Advanced Settings. For more information, see Knowledge Center article CTX224709.

TLS versions

A new setting to select TLS versions has been added in Advanced Settings. The option TLS 1.0, 1.1 (NetScaler Compatibility) is available in the TLS Versions setting to address the TLS handshake failure when connecting through earlier versions of NetScaler. For more information on the TLS handshake failure, see Knowledge Center article CTX221453. By default, the TLS versions is set to TLS 1.0, 1.1, 1.2.

What’s new in 7.4

Auto Tablet Mode

Citrix Receiver for iOS supports switching between Tablet Mode and Desktop Mode when using a Windows 10 VDA. On iOS devices, a Windows 10 VDA launches in Tablet Mode when there is no keyboard or mouse attached. When a keyboard or a mouse or both are connected to the session, the VDA starts in Desktop Mode. Detaching or attaching hardware toggles between Tablet Mode and Desktop Mode. XenApp/XenDesktop 7.14 and later and XenServer 7.2 and later are required for this feature.

This option is on by default. To turn it off, users can go to Settings > Advanced > Auto Tablet Mode.

Note:

There is a known limitation in how iOS detects keyboard switching when an app is running and a keyboard is attached to the device. Because of this OS limitation, tablet-to-desktop mode switching does not happen seamlessly when an external keyboard is attached to the device during a session. The mode shifts only after one of the following three user interactions:

  • Upon selecting a text area again.
  • Three finger touch on the session.
  • Toggling the keyboard from the toolbar.

However, switching from Desktop Mode to Tablet Mode happens seamlessly when the user detaches a keyboard during a session.

What’s new in 7.2

Adaptive transport

Adaptive transport for XenApp and XenDesktop optimizes data transport by applying a new Citrix protocol called Enlightened Data Transport (EDT) in preference to TCP whenever possible. Compared to TCP and UDP, EDT delivers a superior user experience on long-haul WAN and internet connections. EDT dynamically responds to changing network conditions while maintaining high server scalability and efficient use of network capacity. EDT is built on UDP and improves data throughput for all ICA virtual channels, including Thinwire display remoting, file transfer (Client Drive Mapping), printing, multimedia redirection. If UDP is not available, adaptive transport automatically reverts to TCP. For more information, see Adaptive Transport.

Mandatory apps

IT administrators can configure specific applications or desktops as mandatory using StoreFront keywords in the published resource properties. This results in the applications or desktops being automatically subscribed to the user. Users cannot remove these applications or desktops from the Citrix Receiver favorites menu.

What’s new in 7.1.3
