Earlier releases

This section provides information on the new features and fixed issues in the previous releases that we support as per the Lifecycle Milestones for Citrix Workspace app.

2409

What’s new

Feature flag management

Citrix is changing the way it manages feature flags, allowing access to preview features and enabling dynamic management of features in production. To ensure optimal functioning of the following features, which are under feature flags, ensure to enable traffic to the URL features.netscalergateway.netand to use Citrix Workspace app for HTML5 2409:

• Graphics
• App Switcher
• Support for copying image clips
• Generic client IME for East Asian languages

For more information, see Feature flag management.

Fixed issues

• When you upgrade Citrix Workspace app for HTML5 to the 2404.1 version, a session might not start. The issue occurs when the encryption is set to RC5-128. [RFHTMCRM-13828]

2408

What’s new

HDX adaptive throughput

Starting with the 2408 version, HDX adaptive throughput is supported. This feature intelligently fine-tunes the peak throughput of the ICA session by adjusting output buffers. The number of output buffers is initially set at a high value. This high value allows data to be transmitted to the client more quickly and efficiently, especially in high-latency networks.

This feature provides better interactivity, faster file transfers, smoother video playback, and a higher frame rate and resolution resulting in an enhanced user experience.

Session interactivity is constantly measured to determine whether any data streams within the ICA session adversely affect interactivity. If that occurs, the throughput is decreased to reduce the impact of the large data stream on the session and allow interactivity to recover.

Note:

This feature is enabled by default.

Technical Preview

• Secure HDX
• Improved in-session toolbar

For the complete list of Technical Preview features, see the Features in Technical Preview page.

2312

What’s new

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.

For example, consider that you have set a speaker as the Secondary ringer, and your endpoint is connected to the headphones. In this case, Microsoft Teams sends the incoming call ringer to both the headphones and the speaker. 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 isn’t available (for example, a Bluetooth headset)

Note:

By default, this feature is disabled.

For more information, see Support for secondary ringer.

Simulcast implementation for optimized Microsoft Teams video conference calls

Starting with the 2312 release, by default, simulcast support is enabled for optimized Microsoft Teams video conference calls. With this support, the quality and experience of video conference calls across different endpoints are improved. We’re adapting to the proper resolution for the best call experience for all callers.

With this improved experience, each user might deliver multiple video streams in different resolutions (for example, 720p, 360p, and so on). It depends on several factors including endpoint capability, network conditions, and so on. The receiving endpoint then requests the maximum quality resolution that it can handle by that giving all users the best video experience.

Fixed issues

• On iOS devices, when you start a session, the clipboard data from the previous HTML5 session is pasted without your consent. The issue might occur when you use key combinations like Ctrl+a and Ctrl+x with an external keyboard or keep typing when you switch between two applications. [RFHTMCRM-10834] [CVADHELP-23753]

• When you use LongCommandLine arguments to start a session, the session might fail to start. The issue occurs when you use the Apple Safari browser on macOS and iOS devices. [CVADHELP-23753]

Multi-monitor support [Technical Preview]

Previously, the multi-monitor display feature allowed you to create an extra browser tab of the desktop or app session that you were connected to. You could then drag the additional browser tab to the external monitor.

With this release, Citrix Workspace app supports multiple monitors with one click without manual intervention. If there are no external monitors attached to the device, the multi-monitor icon on the in-session toolbar isn’t visible. When you connect an external monitor with the required permissions, the multi-monitor icon is visible. After you click the icon, you can see the window span on all the connected monitors.

For more information see, Multi-monitor support [Technical Preview] in the configure section.

Fixed issues

• After you update the Citrix Workspace app version to 2112 or later, a desktop session on the Internet Explorer browser fails. The following error message appears: ‘Store’ is undefined.

  The issue occurs because of an internal code error. [CVADHELP-19883]

What’s new

This release addresses issues that help to improve overall performance and stability.

Fixed issues

Known issues

Known issue in 2404.1

• For Citrix Workspace app versions 2404.1 or later on StoreFront, when third-party access is blocked via URL rewrite on Citrix Gateway, the app and desktop sessions mightn’t launch successfully. The workaround is to disable the URL rewrite policy applied on the Gateway. [CVADHELP-26253]

Known issues in 2402

• If you attempt to download files or modify files inside the mapped drive from VDA using apps that rely on temporary file, data might get corrupted. For example, browsers, Microsoft office apps such as Excel. [RFHTMCRM-12156] [CVADHELP-24459]

• When you attempt to disconnect a virtual app or desktop session through the toolbar > … > Disconnect button, the session remains active in Citrix Studio. The issue occurs with the on-premises store that is configured with Citrix Gateway. [HDX-60157]

Known issues in 2310

• When you start a desktop session using Citrix Workspace app for HTML5 on the Google Chrome browser, green blocks are visible on the display screen that blocks the UI. The issue might occur when you move an application window inside the launched desktop. [CVADHELP-23377]

• When accessing an HTML5 session from Citrix Gateway using Chromium-based browsers with third-party access blocked through the URL rewrite on Citrix Gateway, the browser’s renderer process consumes excessive memory. This action causes the app to become unresponsive. In addition, the webpage displays the following error: “Not enough memory to open this page.”

  The issue affects Citrix Workspace app for HTML5 versions 2310 and later. As a workaround, disable analytics on the StoreFront server. [CVADHELP-25942]

Limitations

• Disconnecting from a session: When you disconnect from a session by closing a tab or closing the browser, the server might not get notified that the session was disconnected. As a result, the session on the server remains active for the default 180 seconds or the configured session reliability timeout.

  Recommendation: We recommend that you disconnect the session through the toolbar option.

• When Use Hardware Encoding for Video Codec is set to Enabled in Citrix Studio, your screen might appear green during a session through an Intel vGPU VDA. [RFHTMCRM-5521]

• The server falls back to YUV420 even when configured to Graphics-Thinwire YUV444 setting. The graphics-rich applications are limited to the YUV420 range. [RFHTMCRM-5520]

• In a session, when you try to send command + R key combination prompts to disconnect the session instead of remoting to the session. The issue occurs when you use the Safari browser application. [RFHTMCRM-6415]

• When you use Microsoft Teams optimization and share the screen, a red border that indicates the screen sharing is unavailable. [RFHTMCRM-6360]

• External mouse and keyboard aren’t supported with Citrix Workspace app for HTML5 in any browser on Android or iOS operating systems. [RFHTMCRM-6623]

• When you close the browser or the browser tab to disconnect the session, the session state might remain active on the server (Delivery Controller) for sometime. The issue occurs intermittently.

  As a workaround, use the Disconnect option from the secondary menu in the session toolbar. [RFHTMCRM-5457]

• Horizontal scroll from a touchpad isn’t supported.

• When you connect multiple audio devices in a session, you can hear audio from one device only. You might not be able to switch to the other audio device. [HDX-49312]

• In a session, you might not hear the audio from some applications when you disconnect and reconnect to your previous session though toolbar. [HDX-49313]

• Anonymous logins to Citrix Virtual Apps and Desktops from devices with different Device IDs across sessions can sometimes lead to an incorrect user or device license count.

• In a session, when you open Microsoft Excel and do a cut-and-paste operation using a keyboard, the text in the cell isn’t cleared after the cut action. [RFHTMCRM-10426]

• When you transfer files using Client Drive Mapping functionality from your local device to the VDA and conversely, data might get corrupted. [RFHTMCRM-11474]

• When you start a desktop session using Citrix Workspace app, green blocks are visible on the display screen that blocks the UI. The issue might occur when you move an application window inside the launched desktop. [CVADHELP-23377]

• When you use Citrix Workspace app for HTML5 to access published desktops, resizing the window might not work when you adjust the browser window size. The issue occurs when the multi-monitor feature configuration is disabled in Citrix Workspace app for HTML5. In addition, this issue occurs when you have Citrix Virtual Apps and Desktops versions 2308 through 2411.

  As a workaround, enable the multi-monitor feature. To enable:

  1. Locate the configuration.js file. The configuration.js file is in the C:\Program Files\Citrix\Receiver StoreFront\HTML5Client folder.
  2. Edit the configuration.js file and set the value of the trueMMSupportForHTML5 property to true. For example,

   var HTML5_CONFIG = 
   {
       'features': {
           'graphics': {
               'multiMonitor': true,
                   'trueMMSupportForHTML5': false
                       }
                   }
   };
