Released April 24, 2026

Updates

Client

  • Addressed an issue in which NAT traversal would not work in cases where the Gateway hostname was an IP address.

Windows

  • Removed the usage of the Powershell API as it would take a long time to complete when removing DNS rules.

  • Fixed an issue where setting a default level for attention mode with the installer made the client fail to start after an upgrade or installation.

  • Resolved an issue where the certificate integrity check severely impacted client startup performance under certain conditions and sometimes caused install/upgrade to fail.
