What’s new in 2507 LTSR

Support for Debian 12.11, RHEL, and Rocky Linux 9.6

The Linux VDA now supports the following Linux distributions:

  • Debian 12.11
  • RHEL 9.6
  • Rocky Linux 9.6

For more information about supported Linux distributions, see System requirements.

Updated Smartcard and FAS deployment capabilities

The Smartcard and FAS deployment capabilities have been updated, with additional notes specific to Rocky8/9, Ubuntu 24.04, Debian 12/11, and SLES 15.6 Linux platforms included. For more information, see Supported distributions for Smartcard and Supported distribution for FAS.

Update SSSD + FAS + MCS deployment capabilities

SSSD + FAS + MCS deployment capabilities have been updated, with additional notes specific to RHEL and Rocky Linux platforms included. For more information, see Create Linux VDAs with FAS enabled using MCS.

Allow different logon types during session reconnection

Previously, session reconnection required the same logon type as the original session. With this enhancement, users can reconnect using a different logon type. This capability only applies to Username/Password and FAS authentication methods. Set the local registry key to enable this feature:

HKLM\System\CurrentControlSet\Control\Citrix\AccessControl\Login -t REG_DWORD -v allowReconnectCredChange -d 0x00000001
<!--NeedCopy-->

Configurable Logon Banner display timeout

The logon banner display timeout period is now configurable. Previously, the logon banner would automatically proceed after 60 seconds of inactivity. With this feature, you can now customize the logon banner timeout period. See Custom backgrounds and banner messages on session logon screens.

Support for selecting keyboard layout in login UI

Add a keyboard layout selector to the login interface, allowing you to switch between different input languages. This feature ensures that you can enter your username and password correctly, by setting a proper keyboard layout.

Optimized Client Drive Mapping

The following CDM capabilities are optimized:

  • Enhanced file transfer efficiency and large file uploading support (>4GB).
  • Minimized impact of crashed ctxcdm progress. The CDM linked folder is changed to $Home/ctxmnt/drives. See Client drive mapping.

Support CNAME record in LDAPS query

Previously, Linux VDA didn’t support CNAME record in the LDAPS query workflow. Starting with 2507, CNAME record in LDAPS query is supported by default.

Multi-Domain Configuration Support

A new environment variable, CTX_EASYINSTALL_TRUSTED_DOMAINS, is now available for Easyinstall, and TRUSTED_DOMAINS for MCS. You can specify a list of trusted domains. The scripts will automatically update krb5.conf and auto-discover LDAP servers in those trusted domains if the LDAP server list is not specified.

Easy Install GUI Enhancements

The Easy Install GUI now features a restructured component design, including a new installation type selection button that lets you choose from multiple options. You can configure database settings easily with a dedicated page for database configuration. The new “non-domain joined” installation type and quick Proof of Concept (POC) installation type offer more flexibility for various environments. You can save and load configurations, customize optional settings, and streamline the process of setting up both full and POC installations with minimal configuration. For more information, see Create domain-joined VDAs using easy install.

Support displaying more session metrics in Director

Support displaying more session metrics in Director for Diagnose Session Performance issues.

Audio Diagnostic Command Line Tool

The audio diagnostic command line tool has been enhanced in version 2507 to provide additional diagnostic information. For more information, see Audio diagnostic command line tool.

Audio Quality Enhancer for Adaptive Audio

Starting with version 2507, the Audio Quality Enhancer is enabled by default for adaptive audio. This feature maintains clear audio during brief network disruptions by adapting to changing network conditions, ensuring consistent audio performance during both playback and recording. For more information, see Audio Quality Enhancer.

What’s new in earlier releases

For new features included in the releases that shipped after the 1912 LTSR through the 2411 CR, see What’s new history.
