NoMachine makes available version 9.10.3 to provide some fixes for issues affecting earlier releases, as well as security patches addressing potential vulnerabilities in server-side components and web sessions. This release also improves the handling of CA system certificates on Windows and delivers updated OpenSSL libraries with the latest security fixes and compatibility improvements.

Improvements to how CA system certificates are handled
NoMachine is now able to use CA system certificates on Windows without the need to specify their path in the "Certificate authority" key in user's player.cfg.

New OpenSSL libraries
OpenSSL libraries shipped by NoMachine client and server packages have been updated to v3.5.8. The full list of CVE patched by the new OpenSSL 3.5.8 is available on their Official web site at: https://openssl-library.org/news/openssl-3.5-notes/

Updates to the nxhtd component
The nxhtd component included in commercial server packages is now based on httpd 2.4.69, changes in the new version of Apache are listed here: https://downloads.apache.org/httpd/CHANGES_2.4.69

Important Notices

Customers of Enterprise Cloud Server Cluster v8 who wish to upgrade to v9 should refer to the instructions at: https://www.nomachine.com/AR11V01257. 'Online' subscriptions v9 for the enterprise products require a NoMachine server v9 and are not compatible with servers v8 or earlier. Please do not hesitate to contact us via any of the available channels for assistance.

All NoMachine Enterprise software for evaluation can now be activated using a license file which is generated from the User Area and activated online.  For further instructions, users can consult the following article https://kb.nomachine.com/AR10K00713.

The RPM packages are now built using a more recent version of RPM in order to support also SHA256 digest and to allow signature verification on recent RPM-based systems. On old OS versions like Open SUSE 11.2 and earlier, it will be necessary to install NoMachine tar.gz packages.

The current version doesn't provide full support for Wayland-native virtual desktops as required by adopting GNOME 49, a possible temporary solution is to downgrade GNOME or adopt a lightweight desktop. More details are available here: https://kb.nomachine.com/AR10W01330
