UPGRADING
Nothing special.
-NEW FEATURES
-============
-
-Logging
--------
-
-The logging code now supports logging to multiple backends. In
-addition to the previously available syslog and file backends, the
-backends for logging to the systemd-journal, lttng and gpfs have been
-added. Please consult the section for the 'logging' parameter in the
-smb.conf manpage for details.
-
-Spotlight
----------
-
-Support for Apple's Spotlight has been added by integrating with Gnome
-Tracker.
-
-For detailed instructions how to build and setup Samba for Spotlight,
-please see the Samba wiki: <https://wiki.samba.org/index.php/Spotlight>
-
-New FileChangeNotify subsystem
-------------------------------
-
-Samba now contains a new subsystem to do FileChangeNotify. The
-previous system used a central database, notify_index.tdb, to store
-all notification requests. In particular in a cluster this turned out
-to be a major bottleneck, because some hot records need to be bounced
-back and forth between nodes on every change event like a new created
-file.
-
-The new FileChangeNotify subsystem works with a central daemon per
-node. Every FileChangeNotify request and every event are handled by an
-asynchronous message from smbd to the notify daemon. The notify daemon
-maintains a database of all FileChangeNotify requests in memory and
-will distribute the notify events accordingly. This database is
-asynchronously distributed in the cluster by the notify daemons.
-
-The notify daemon is supposed to scale a lot better than the previous
-implementation. The functional advantage is cross-node kernel change
-notify: Files created via NFS will be seen by SMB clients on other
-nodes per FileChangeNotify, despite the fact that popular cluster file
-systems do not offer cross-node inotify.
-
-Two changes to the configuration were required for this new subsystem:
-The parameters "change notify" and "kernel change notify" are not
-per-share anymore but must be set globally. So it is no longer
-possible to enable or disable notify per share, the notify daemon has
-no notion of a share, it only works on absolute paths.
-
-New SMB profiling code
-----------------------
-
-The code for SMB (SMB1, SMB2 and SMB3) profiling uses a tdb instead
-of sysv IPC shared memory. This avoids performance problems and NUMA
-effects. The profile stats are a bit more detailed than before.
-
-Improved DCERPC man in the middle detection for kerberos
---------------------------------------------------------
-
-The gssapi based kerberos backends for gensec have support for
-DCERPC header signing when using DCERPC_AUTH_LEVEL_PRIVACY.
-
-SMB signing required in winbindd by default
--------------------------------------------
-
-The effective value for "client signing" is required
-by default for winbindd, if the primary domain uses active directory.
-
-Experimental NTDB was removed
------------------------------
-
-The experimental NTDB library introduced in Samba 4.0 has been
-removed again.
-
-Improved support for trusted domains (as AD DC)
------------------------------------------------
-
-The support for trusted domains/forests has improved a lot.
-
-samba-tool got "domain trust" subcommands to manage trusts:
-
- create - Create a domain or forest trust.
- delete - Delete a domain trust.
- list - List domain trusts.
- namespaces - Manage forest trust namespaces.
- show - Show trusted domain details.
- validate - Validate a domain trust.
-
-External trusts between individual domains work in both ways
-(inbound and outbound). The same applies to root domains of
-a forest trust. The transitive routing into the other forest
-is fully functional for kerberos, but not yet supported for NTLMSSP.
-
-While a lot of things are working fine, there are currently a few limitations:
-
- - Both sides of the trust need to fully trust each other!
- - No SID filtering rules are applied at all!
- - This means DCs of domain A can grant domain admin rights
- in domain B.
- - It's not possible to add users/groups of a trusted domain
- into domain groups.
-
-SMB 3.1.1 supported
--------------------
-
-Both client and server have support for SMB 3.1.1 now.
-
-This is the dialect introduced with Windows 10, it improves the secure
-negotiation of SMB dialects and features.
-
-New smbclient subcommands
--------------------------
- - Query a directory for change notifications: notify <dir name>
- - Server side copy: scopy <source filename> <destination filename>
