What’s New

All releases are cumulative and contain the features introduced in earlier releases. For previous versions, see HACloud Documentation.

Features and fixes include

  • Users can now double-click to select a word in the Web Client terminal. (2.7.1)

  • Log4j library has been upgraded to version 2.17.1 to mitigate multiple CVEs. (2.7.1)

  • Information on how to run HACloud as a dedicated, non-administrative, user (2.7.1)

  • 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)

  • 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

  • Due to Microsoft continuing to retire Internet Explorer 11, our ability to resolve IE 11 browser specific issues will be limited after June 2022. We will continue to support IE 11 on versions of HACloud that currently support it, based on the Product Support Lifecycle, but will be removing support for IE 11 in HACloud 3 and greater. (2.7.1)

  • To help prevent cross-site request forgery attacks, the default SameSite attribute on the session server cookie has been updated from None to Lax. This change may affect the JavaScript SDK and SAML authentication behind a load balancer. You can edit this attribute if needed. See Setting the SameSite Attribute.

  • 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)

  • 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)
