NoMachine 8.0.168
Key enhancements in this new major version are:
- Cloud Server Family Products now extended
- Designed to satisfy needs of different business realities, the new range of products covers from small-sized to very large environments. The failover cluster capabilities for high available access are now moved into a specific product, the Enterprise Cloud Server Cluster. To mirror the new Cloud Server family, a cluster-specific product is made available also in the terminal server family (Enterprise Terminal Server Cluster) and some products have been renamed.
- The local and remote server administrator's UI
- A completely redesigned interface for easier access to server configuration also from remote provides a much more improved experience to users and administrators, especially for Cloud Server and nodes management, with the possibility to monitor connections and users in the whole system.
- Guest Desktop Sharing Users
- Connect as a guest to the remote physical desktops without the need to have a system account, always upon the approval of the desktop owner. Available also in the free version, it's ideal also for on-the-fly connections to help friends remotely and everywhere.
- Switching on/off the interactive mode at run-time
- The desktop owner can give interaction or view-only permissions to the connected user or guest at any moment during the life of the session by a simple click via the Monitor menu (!M) in the system tray.
- Nat-traversal inverse connection for Cloud Servers
- Perfect for a DMZ network which isolates public services reachable by the Internet from the corporate LAN, the 'inverse connection' reverses the direction of communication. In this way, connection is established from a node to the Cloud Server, getting rid of the need to open a port in the corporate firewall.
- Enhanced support for multiple GPUs
- Workload for hardware accelerated video encoding can be now distributed among all the available GPUs according to a load-balance algorithm or off-loaded to a specific GPU dedicated to NoMachine.
- H.264 hardware encoding on macOS
- H.264 hardware encoding is now available also for NoMachine servers running on macOS, extending support for 3D hardware acceleration also on that platform.
- Native packages for Windows 64bit and macOS M1/M2
- This version provides also client and server packages built for Windows 64-bit architecture and universal packages suitable for macOS equipped with Intel or Silicon processor. The native package for M1/M2 restores USB support on macOS, not available with Intel packages running under Rosetta 2 emulator.

Minor software update aimed at consolidating the update procedure from version 6 to version 7 for Cloud Server multi-host environments. This version 7.0.209 fixes the following:
- TR12R09965 - Cloud Server, after update, may not clearly state that the reason why it cannot connect to the child server is the different major version on such machine


NoMachine 7.0.208
Simplified UI navigation and connection management:
- NoMachine player and server configuration are now grouped together to facilitate navigation of the UI. Connections are started in a new window to make settings and connection configuration easily accessible to the user even when a remote desktop session is open.

Streamlined connection creation:
- Connection creation is faster thanks to one unique interface from which player and from this release also webplayer sessions can be started. Any associated session options are easily accessible and configurable from the simplified layout.

The Machines panel:
- The Machines panel, which replaces 'Recent Connections' provides an overview of stored connections and any desktops available on the LAN. The novelty with this release is that web-based sessions are also visualized as well as recordings available for play-back on the local host.

Simplified menu in system tray:
- The monitor menu available in the system tray has been updated to better integrate with the native OS theme and style, offering an eye-friendly view of the fast-track options available

Improved support for client-side multi-monitors:
- Virtual desktop sessions available in the Terminal Server for Linux products now adapt seamlessly to client-side multi-monitor workspaces. This means maximized applications can span to a single monitor or across all monitors.

Automatic assignment of remote Enterprise Desktop host:
- When there are hundreds of near-identical Enterprise Desktops associated to a Cloud Server, there is often a need for users to connect on a 'first come, first served' basis. A new algorithm checks what Enterprise Desktop hosts are free to use or whether a user is already logged in.

Profile rules propagation:
- Cloud Server can now broadcast rules to all its associated child servers. This ensures that administrators can efficiently manage corporate policies from one central location
- Authentication with separate accounts in multi-server environments
- Admins of Cloud Server environments adopting multiple authentication levels (e.g. AD user authentication and subdomains) can decide whether to allow pass-through authentication for each user, where authentication on the child server is the same as that on the Cloud Server, or ensure that the user logs in with a different username.

Enable automatic recording at session start-up:
- NoMachine’s screen recording feature can now be configured to automatically record remote sessions for all or specific users, making it a useful tool for monitoring or audit purposes

Users can choose their preferred Linux desktop:
- In virtual desktop sessions (Terminal Server products only), NoMachine can now automatically detect any additional Linux desktop installed by the administrator on the host and allow the user to choose from all those available if this is the server’s configured preference.

Wake-on-LAN:
- NoMachine clients can now wake up NoMachine servers residing on the same local network. This is made possible by sending 'magic packets' from the client to the remote PC or Mac. The requirements for operating Wake-on-LAN are that the remote computer is connected via ethernet, and the hardware must support Wake-on-LAN with a compatible BIOS and network card.

Fixes and implementations:
- Enhancements to the NoMachine User Interface
- Making it possible to treat multi-monitors on the client as separate monitors in virtual desktop sessions
