.NET Framework version upgrade

This release requires .NET Framework Version is 4.6.2 or later. If you are trying to install or upgrade to Citrix Workspace app 1904 or later and the requisite version of the .NET Framework is not available on your Windows system, the Citrix Workspace app installer will download and install the required version of the .NET Framework.

Note:

If you are trying to install or upgrade Citrix Workspace app with non-administrator privileges and.NET Framework 4.6.2 or greater is not present on the system, the installation fails.

For troubleshooting the issues with the .NET Framework installation, see the Knowledge Center article CTX250044.

Changes in the Citrix Workspace app installer package

In earlier releases, the Microsoft Visual C++ Redistributable binaries were packaged individually with the Citrix Workspace app installer. The binaries were copied locally inside the Citrix Workspace app installation folder during the Citrix Workspace app installation.

This release requires Microsoft Visual C++ Redistributable 14.16.27012.6 or later. Starting with Version 1904, Microsoft Visual C++ Redistributable individual binaries are no longer packaged with the Citrix Workspace app installer. Instead, the Citrix Workspace app installer includes the Microsoft Visual C++ Redistributable 14.16.27012.6 installer. When you install Citrix Workspace app, the Citrix Workspace app installer checks whether the Microsoft Visual C++ Redistributable package is present on the system and installs it if necessary.

Note:

If you are trying to install Citrix Workspace app with non-administrator privileges, and the Microsoft Visual C++ Redistributable package is not present on the system, the installation fails.

Only an administrator can install the Microsoft Visual C++ Redistributable package.

For troubleshooting issues with the .NET Framework or the Microsoft Visual C++ Redistributable installation, see Citrix Knowledge Center article CTX250044.

Cryptographic update

This feature is an important change to the secure communication protocol. Cipher suites with the prefix TLS_RSA_ do not offer forward secrecy and are considered weak. These cipher suites were deprecated in Citrix Receiver version 13.10 with an option for backward compatibility.

In this release, the TLS_RSA_ cipher suites have been removed entirely. Instead, this release supports the advanced TLS_ECDHE_RSA_ cipher suites. If your environment is not configured with the TLS_ECDHE_RSA_ cipher suites, client launches are not supported due to weak ciphers.

The following advanced cipher suites are supported:

• TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384 (0xc030)
• TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384 (0xc028)
• TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA (0xc013)

DTLS v1.0 supports the following cipher suites:

• TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA
• TLS_EMPTY_RENEGOTIATION_INFO_SCSV

DTLS v1.2 supports the following cipher suites:

• TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384
• TLS_ECDHE_RSA_WITH_AES_256_CBC_SHA384
• TLS_ECDHE_RSA_WITH_AES_128_CBC_SHA
• TLS_EMPTY_RENEGOTIATION_INFO_SCSV
