Release Announcements ===================== This is the first release candidate of Samba 4.1. This is *not* intended for production environments and is designed for testing purposes only. Please report any defects via the Samba bug reporting system at https://bugzilla.samba.org/. Samba 4.1 will be the next version of the Samba suite and includes all the technology found in both the Samba4 series and the stable 3.x series. The primary additional features over Samba 3.6 are support for the Active Directory logon protocols used by Windows 2000 and above. If you are upgrading, or looking to develop, test or deploy Samba 4.1 releases candidates, you should backup all configuration and data. UPGRADING ========= NEW FEATURES ============ Directory database replication (AD DC mode) =========================================== Directory replication has been reworked in order to improve the correctness and efficiency. As a net effect of it, replication with other domain controllers with a heavily modified schema is now possible (ie. Windows 2012 DCs or other Windows DC with exchange installed) and replication didn't fail anymore in such environments. Server-Side Copy Support ======================== Samba 4.1.0 adds support for server-side copy operations via the SMB2 FSCTL_SRV_COPYCHUNK request. Clients making use of server-side copy support, such as Windows Server 2012, should experience considerable performance improvements for file copy operations, as file data need not traverse the network. This feature is enabled by default on the smbd file server. Btrfs Filesystem Integration ============================ The Btrfs VFS module provided with Samba 4.1.0 further improves the performance of server-side copy operations on shares backed by a Btrfs filesystem. It does so by allowing multiple files to share the same on-disk extents, avoiding the unnecessary duplication of source and destination file data during a server-side copy operation. This feature can be explicitly enabled on smbd shares backed by a Btrfs filesystem with the smb.conf parameter: vfs objects = btrfs REMOVED COMPONENTS ================== The Samba Web Administration Tool (SWAT) has been removed. ###################################################################### Changes ####### smb.conf changes ---------------- Parameter Name Description Default -------------- ----------- ------- password level Removed set directory Removed use ntdb New No CHANGES SINCE 4.0.7 =================== o Michael Adam KNOWN ISSUES ============ RUNNING Samba 4.1 as an AD DC ============================= A short guide to setting up Samba 4 as an AD DC can be found on the wiki: http://wiki.samba.org/index.php/Samba4/HOWTO ####################################### Reporting bugs & Development Discussion ####################################### Please discuss this release on the samba-technical mailing list or by joining the #samba-technical IRC channel on irc.freenode.net.
