NoMachine makes available new version 9 packages to provide updates to third party libraries shipped with NoMachine software and to fix a number of issues affecting previous versions. The nxhtd and libexpat libraries, now based on httpd 2.4.66 and expat v2.7.3, incorporate fixes for CVE-2025-65082 and CVE-2025-59375, respectively. Whilst NoMachine may not be directly impacted by these vulnerabilities, keeping library versions up to date is essential for overall security and compatibility. This release additionally implements improvements to NoMachine's load-balancing custom algorithm by allowing NoMachine virtual desktops to be load-balanced among the nodes of an Enterprise Terminal Server according to the RAM usage on the nodes.

These are the trouble reports solved by this 9.3.7 release:

TR12W11654 - After a quick disconnection and reconnection, sometimes the sessions cannot be resumed
TR11W11633 - Cannot enter filename when copying a file to Ubuntu 24 in web sessions started from Chrome

TR10W11617 - Unexpected exit of server daemon process after adding a license
TR11W11619 - Some applications don't work correctly in KDE Plasma when NoMachine 9.2 is installed
TR11W11627 - Connection notification should not be clickable when the server status is not accessible
TR12W11644 - Load-balancing of Linux virtual desktops may not work properly when 'Load average' or 'system load' algorithms are used
TR10W11586 - Black screen connecting to Rocky Linux 9 server
TR11W11618 - NoMachine RPM packages cannot be verified on recent RPM-based systems
