2207

What’s new

Enhancement to improve audio quality

Previously, the maximum output buffering value to play the audio smoothly was 200 ms in Citrix Workspace app. Because of this value set, 200 ms latency was added in the playback scenario. This maximum output buffering value had an impact on interactive audio applications as well.

With this enhancement, the maximum output buffering value is decreased to 50 ms in Citrix Workspace app. As a result, the user experience on the interactive audio application is improved. Also, the Round trip time (RTT) is decreased by 150 ms.

Starting with this release, you can select the appropriate playback threshold and pulse audio prebuffer to improve the audio quality. For this enhancement, the following parameters are added in the [ClientAudio] section of the module.ini file:

PlaybackDelayThreshV4 – To specify the initial level of output buffering in milliseconds. Citrix Workspace app tries to maintain this level of buffering throughout a session’s duration. The default value of the PlaybackDelayThreshV4 is 50 ms. This parameter is valid only when AudioRedirectionV4 is set to True.
AudioTempLatencyBoostV4 – When the audio throughput undergoes a sudden spike or isn’t enough for an unstable network, this value increases the output buffering value. This increase in the output buffering value provides smooth audio. However, the audio might be slightly delayed. The default value of AudioTempLatencyBoostV4 is set to 100 ms. This parameter is only valid when AudioRedirectionV4 is set to True and AudioLatencyControlEnabled is set to True. By default, the value of AudioLatencyControlEnabled is set to True.

For more information on how to enable this enhancement, see the Enhancement to improve audio quality section in the Audio documentation.

Composite USB device redirection

Starting with this release, Citrix Workspace app allows splitting of composite USB devices. A composite USB device can perform more than one function. These functions are accomplished by exposing each of those functions using different interfaces. Examples of composite USB devices include HID devices that consist of audio and video input and output.

Currently composite USB device redirection is available in desktop session only. The split devices appear in the Desktop Viewer.

Earlier when a device was unplugged and plugged in during a session, the device was redirected automatically. As a result, the device was auto connected to the VDA. With this release, you are required to enable auto-redirection manually through configuration file settings. Auto-redirection of composite USB devices is disabled, by default.

For more information on configuring composite USB device redirection, see the Composite USB device redirection section in the USB documentation.

Improved audio echo cancellation support [Technical Preview]

By default, the echo cancellation feature is disabled. During real-time user cases, it’s recommended to turn on the echo cancellation if the speaker is used instead of the headset.

Limitation:

By design, the echo cancellation feature is disabled for high quality audio.

For more information, see the Improved audio echo cancellation support section in the Audio documentation.

Note:

Technical previews are available for customers to test in their non-production or limited production environments, and to give customers an opportunity to share feedback. Citrix does not accept support cases for feature previews but welcomes feedback for improving them. Citrix might or might not act on feedback based on its severity, criticality, and importance. It is advised that Beta builds aren’t deployed in production environments.

Support for secondary ringer

You can use the Secondary ringer feature to select a secondary device on which you want to get the incoming call notification when Microsoft Teams is optimized (Citrix HDX optimized in About/Version). For example, consider that you have set a speaker as the Secondary ringer and your endpoint is connected to the headphone. In this case, Microsoft Teams sends the incoming call signal to the speaker even though your headphones are the primary peripheral for the audio call itself. You can’t set a secondary ringer in the following cases:

When you aren’t connected to more than one audio device
When the peripheral is not available (for example, Bluetooth headset)

What’s new

Authentication enhancement for Storebrowse

Starting with this release, the authentication dialog is present inside Citrix Workspace app and the store details are displayed on the logon screen. This feature provides a better user experience. The authentication tokens are encrypted and stored so that you don’t need to reenter credentials when your system or session restarts.

You can also toggle the authentication enhancement for Storebrowse feature off or on using the StorebrowseIPC key in the AuthmanConfig.xml file. By default, the toggle functionality is disabled.

The authentication enhancement supports storebrowse for the following operations:

Storebrowse -E: Lists the available resources.
Storebrowse -L: Launches a connection to a published resource.
Storebrowse -S: Lists the subscribed resources.
Storebrowse -T: Terminates all sessions of the specified store.
Storebrowse -Wr: Reconnects the disconnected yet active sessions of the specified store. The [r] option reconnects all the disconnected sessions.
storebrowse -WR: Reconnects the disconnected yet active sessions of the specified store. The [R] option reconnects all the active and disconnected sessions.
Storebrowse -s: Subscribes the specified resource from a given store.
Storebrowse -u: Unsubscribes the specified resource from a given store.
Storebrowse -q: Launches an application using the direct URL. This command works only for StoreFront stores.

Note:

You can continue to use the remaining storebrowse commands as used earlier (using AuthMangerDaemon).

The authentication enhancement is applicable for cloud deployments only.

With this enhancement, the persistent login feature is supported.

For more information, see the Authentication enhancement.

With this functionality, the SSO to Citrix DaaS sessions is extended up to a period of 365 days. This extension is based on the lifetime of Long-Lived Tokens. Your credentials are cached by default for 4 days or Lifetime whichever is lower. And, then extended when you become active within these 4 days by connecting to the Citrix Workspace app.

Note:

Technical previews are available for customers to test in their non-production or limited production environments, and to give customers an opportunity to share feedback. Citrix does not accept support cases for feature previews but welcomes feedback for improving them. Citrix might or might not act on feedback based on its severity, criticality, and importance. It is advised that Beta builds aren’t deployed in production environments.

For more information, see Persistent login.

Email-based auto-discovery of store

You can now provide your email address in Citrix Workspace app to automatically discover the store associated with the email address. If there are multiple stores associated with a domain, by default the first store returned by the Global App Configuration Service is added as the store of choice. Users can always switch to another store if necessary.

For more information, see the Email-based auto-discovery of store section at Adding store URL to Citrix Workspace app documentation.

Fixed issues

The DNS server in a customer environment with limited internet access might not resolve the URL, clientstream.launchdarkly.com. As a result, Citrix Workspace app sends many DNS queries (>1000 within three seconds per day) to the URL. [CVADHELP-19559]
When the App Protection feature is enabled, the anti-keylogging functionality might not work for the Authentication Manager interface that uses the UIDialogLibWebKit3.so library. This issue is resolved in the GNOME and KDE desktop environment. [RFLNX-8027]
Attempting to print from a VDA session running on Raspberry Pi ARMHF client version 3 or 4 might make the session unresponsive. [CVADHELP-18506]
When you launch the self-service user interface with the default settings, the following error message might appear:

“Response for Secondary Token request is not 200/400/404 42”

This issue occurs on Fedora 35. [RFLNX-8603]

What’s new

Support for EDT IPv6

Starting with this release, Citrix Workspace app supports EDT IPv6.

Support for TLS protocol version 1.3

Starting with this release, Citrix Workspace app supports Transport Layer Security protocol (TLS) version 1.3. For more information, see TLS.

Custom web stores

Starting with 2203, you can access your organization’s custom web store from the Citrix Workspace app.

Note:

The Pinning multi-monitor screen layout feature is not supported in the custom web store.

For more information, see Custom web stores.

Authentication enhancement experimental feature

Starting with this release, authentication enhancement supports storebrowse for the following operations:

Storebrowse -E to list the available resources.
Storebrowse -L to launch a connection to a published resource.
Storebrowse -S to list the subscribed resources.

Note:

You can continue to use the remaining storebrowse commands in the AuthMangerDaemon and will be supported with authentication enhancement in the future release.

For more information, see Authentication enhancement for Storebrowse.

Keyboard layout synchronization enhancement

Keyboard layout synchronization enables you to switch among preferred keyboard layouts on the client device. This feature is disabled by default. When enabled, the client keyboard layout automatically synchronizes to the Citrix Virtual Apps and Desktops and Citrix DaaS (formerly Citrix Virtual Apps and Desktops service) session.

Starting with version 2203, Citrix Workspace app supports the following three different keyboard layout synchronization modes:

Sync only once - when session launches – Based on the KeyboardLayout value in the wfclient.ini file, the client keyboard layout is synchronized to the server when the session launches. If the KeyboardLayout value is set to 0, the system keyboard is synchronized to VDA. If the KeyboardLayout value is set to a specific language, the language-specific keyboard is synchronized to VDA. Any changes you make to the client keyboard layout during the session do not take effect immediately. To apply the changes, sign out and sign in to the app. The Sync only once - when session launches mode is the default keyboard layout selected for Citrix Workspace app.
Allow dynamic sync - This option synchronizes the client keyboard layout to the server when you change the client keyboard layout.
Don’t sync - Indicates that the client uses the keyboard layout present on the server.

For more information, see Keyboard layout synchronization.

Multi-window chat and meetings for Microsoft Teams

You can use multiple windows for chat and meetings in Microsoft Teams, when optimized by HDX in Citrix Virtual Apps and Desktops 2112 or higher. You can pop out the conversations or meetings in various ways. For details about the pop-out window feature, see Microsoft Teams Pop-Out Windows for Chats and Meetings.

If you’re running an older version of Citrix Workspace app or Virtual Delivery Agent (VDA), remember that Microsoft will deprecate the single-window code in the future. However, you can upgrade to a version of the VDA or Citrix Workspace app that supports multiple windows (2203 and greater). To upgrade to a higher version, you will have a minimum of nine months after this feature is generally available.

Note:

This feature is available only after the roll-out of a future update from Microsoft Teams. When the update is rolled-out by Microsoft, you can check CTX253754 for the documentation update and the announcement.

Enhancement to auto-redirection of USB devices

Earlier when a device was unplugged and plugged in during a session, the device was auto-redirected. As a result, the device was auto-connected to the VDA. With this release, you are required to enable auto-redirection manually through configuration file settings. Auto-redirection of USB devices is disabled, by default. For more information, see USB section.

Fixed issues
