  • Windows Authentication via Kerberos is now available for end users launching sessions via the session server (2.7)

  • Management and Security Server (MSS) has been made more secure by moving to HTTPS only. (2.7)

  • You can now easily reset the password to the metering service if forgotten. (2.7)

  • Communication from the Security Proxy to MSS when exporting settings has been upgraded to HTTPS. (2.7)

  • You now have the ability to add Subject Alternative Names to certificates while installing HACloud and MSS. (2.7)

  • TLS 1.3 is now supported and enabled. Clients that do not yet support TLS 1.3 will fall back to TLS 1.2. (2.6.1)

  • The ability to Cut text, similar to Copy and Paste, has been added to the HACloud Web Client. (2.6.1)

  • Support is now available for Plus AutoTab and TabOrder. These features provide greater control over cursor tabbing behavior on Plus decorated screens. (2.6.1)

  • A wait.forHostSettle method has been added to the Web Client macro API, Windows Connector API and the JavaScript API. (2.6.1, 2.7.0)

Changes in Behavior

  • MSS has moved to use HTTPS exclusively to increase security. HTTP has been disabled on all endpoints. In upgrades, where session servers had been configured to access MSS, Metering or the Terminal ID Manager (TIDM) over HTTP they will need to be updated to use the HTTPS port in (2.7)

  • TLS 1.0, TLS 1.1 have been removed. Both TLS 1.3 and TLS 1.2 are now available. HACloud Sessions that were previous configured for "TLS 1.2 - TLS 1.0" (in Connection Settings) will be updated to "TLS 1.2" the next time they are updated by an administrator (2.7)

  • As a result of updated encryption libraries, customers who use headless server-based installations may experience system delays if system entropy is too low. Insufficient entropy may lead to the installation process hanging or degraded server performance. Some platforms already install and enable an entropy service by default, and the issue will not be noticed. If needed, a hardware or software solution can remedy the issue. See the Knowledge Base article, Ensuring Sufficient Entropy to Avoid System Delays. (2.6.2)

  • When launching an HACloud session from the Assigned Sessions List, a new session is now opened each time a session is selected, even if a session by that name is already open. (2.7)
