The Samba 4.25 release introduces experimental support for SMB3 Persistent Handles, designed to improve fault tolerance. This feature allows clients to maintain file access after server restarts or interruptions by reusing existing handles, though developers warn of significant performance overhead due to increased storage operations.
A new Ceph RGW VFS module is included, enabling users to share Ceph Object Gateway buckets via the SMB protocol. This integration bridges object storage with traditional Windows and Linux file-sharing environments, expanding the utility of Ceph infrastructure for enterprise users.
Security and management updates in this version include improvements to JSON-formatted audit logs, facilitating easier integration with security and analysis platforms. Additionally, the default domain encryption setting has been updated to AES, moving away from older, less secure encryption standards.
Samba 4.25 is now available as the latest stable release, with source code and full documentation provided. While the update offers broad improvements for file service continuity and infrastructure compatibility, users are advised to evaluate the experimental features before deploying them in production environments.
