NoMachine

What's new in this version:

NoMachine 7.6.2
- OMachine makes available updated packages to fix some minor issues affecting earlier versions such as changing default limits for configuration keys regarding virtual desktop and connection numbers, and resizing the client on Windows which doesn't keep aspect ratio.
- Additionally, this release prevents a vulnerability affecting SSH connections.

This occurs on all platforms when connecting by SSH and affects all server types which support the SSH protocol.

NoMachine 7.0.209
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.
