Citrix is committed to complying with the Security Advisories published by Microsoft. Effective January 1, 2016, Microsoft deprecated the SHA-1 code signing certificate. Citrix has since moved to using the requisite code signing certificate. However, the following Citrix software updates were under development while the transition was underway. Those updates were initially produced and released using the SHA-1 certificate after January 1, 2016. As a result, when you downloaded the affected updates using the Microsoft Internet Explorer or Edge browsers, a SmartScreen Filter warning appeared.

Citrix has since released new versions of these updates that are resigned with the requisite replacement certificate.
