SerNet announces the launch of SAMBA+ 4.20.0. This is the latest stable release series of Samba for Enterprise Linux. Available immediately for a variety of platforms including SUSE, Red Hat, Debian GNU/Linux, Ubuntu, and for AIX. This release introduces multiple enhancements for up-to-date enterprise environments.

Standing out is the new Service Witness Protocol [MS-SWN], developed by Stefan Metzmacher from SerNet. This enhances the stability and monitoring capabilities within clustered environments. This protocol is essential for enterprises using high-availability solutions, allowing clients to monitor their SMB connections more effectively across cluster nodes. This development ensures that SAMBA+ remains at the forefront of networked system resilience, providing scalable solutions for large-scale deployments.

Additionally, the release of SAMBA+ 4.20 transitions previous series into different support phases: Samba 4.19 enters maintenance mode, Samba 4.18 shifts to security fixes only, and updates for Samba 4.17 will be discontinued. Users are encouraged to upgrade to the latest version to take advantage of the new features and improved security protocols.

For existing SAMBA+ subscribers, the new release is included in your current subscription. New customers can obtain SAMBA+ through a software subscription available at our online shops (USD Pricing: US SAMBA+ Shop, EUR Pricing: World SAMBA+ Shop). All details about subscription options and pricing are listed there.

As enterprises increasingly rely on robust, secure, and scalable solutions, SAMBA+ 4.20.0 represents a step forward. We invite all users to read the detailed release notes to ensure a smooth transition and to leverage the full capabilities of this release.

Please make sure to test thoroughly before upgrading. For further assistance, upgrade paths, and deployment strategies, please consult our SAMBA+ HowTo collection or contact our support team directly through our website.

The recording of the talk "SMB for Linux with SMB3 POSIX extensions" by Volker Lendecke, longtime member of the Samba core team and co-founder of SerNet, is now available on our YouTube channel. Lendecke gave the talk at FOSDEM 2024 in Brussels, one of the most important conferences in the open source community.

In his presentation, Lendecke discussed the advances in the SMB3 protocol and its impact on network file sharing on Linux. The session offered insights into the SMB3 POSIX extensions that make SMB a real alternative to NFS with all the semantics Linux clients expect. Volker Lendecke not only gave an insight into the current functionalities, but also an outlook on future developments. The discussion also included how these extensions can improve the efficiency and compatibility of file sharing between different operating systems.

The recording of the talk is a valuable resource for anyone interested in the latest developments in the world of network file sharing or who would like to deepen their knowledge of SMB3 and its application to Linux systems.
