NoMachine makes available an important software update of version 9, providing some key improvements designed to optimize user experience and performance, and fix issues affecting the previous 9 release. What's more, from now on, all users creating their account will get a free 7-day evaluation period so they can experience the power of NoMachine Network firsthand. The free evaluation has also been assigned to all those users who created their account since the release of NoMachine 9, so go enjoy the power of Network! Another important change is how the session window works upon a resize: it keeps the ratio of the remote desktop, after the operation, something that is the standard on the market for this kind of application and more in line with what users expect.

Features and enhancements:

Free NoMachine Network evaluation

Unlock a 7-day free trial of NoMachine Network and enjoy how powerful Network is. As soon as you create your NoMachine account, your one-week evaluation is activated. It's enough to login to the Network service in the NoMachine Player with your account and insert the Machine Id of the target computer already added to NoMachine Network. Both client and server sides must have a NoMachine 9 installed in order to connect using the Network service.

Behaviour of session window during resize

The session window now keeps the ratio of the remote desktop during resize operations when scale-to-window is enabled, that is the default. For more details, refer to: https://www.nomachine.com/AR07W01315.

Add Machine Id to Machines book shortcut

When creating a NoMachine Network connection using the Machine Id, a shortcut is now conveniently placed in the connection creation panel to allow the user to add a new entry to the Network Machines book.

New server.cfg keys

It's possible to specify a list of interfaces and a range of ports for NoMachine Network connections in the new server.cfg keys, NetworkInterfaces and NetworkPort.

NoMachine VPN and nftables subsystem

The NoMachine VPN now works also with nftables subsystem used by some Linux distributions like recent Debian.

Changes to AcceptedWebMethods key

The behaviour of the AcceptedWebMethods key is no longer positional. The web player by default will always try to use webrtc and fall back to mjpeg when webrtc is not possible, regardless of the order of the values.

Updates to third-party libraries

NoMachine packages now sport updated libraries OpenSSL-3.0.17 and other third party components.
