Release Announcements
=====================
-This is the first release candidate of Samba 4.1. This is *not*
+This is the first preview release of Samba 4.8. 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.
+Samba 4.8 will be the next version of the Samba suite.
UPGRADING
=========
+NEW FEATURES/CHANGES
+====================
-NEW FEATURES
-============
+KDC GPO application
+-------------------
-Directory database replication (AD DC mode)
-===========================================
+Adds Group Policy support for the samba kdc. Applies password policies
+(minimum/maximum password age, minimum password length, and password
+complexity) and kerberos policies (user/service ticket lifetime and
+renew lifetime).
-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.
+Adds the samba_gpoupdate script for applying and unapplying
+policy. Can be applied automatically by setting
+ 'server services = +gpoupdate'.
-Server-Side Copy Support
-========================
+Time Machine Support with vfs_fruit
+===================================
+Samba can be configured as a Time Machine target for Apple Mac devices
+through the vfs_fruit module. When enabling a share for Time Machine
+support the relevant Avahi records to support discovery will be published
+for installations that have been built against the Avahi client library.
-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.
+Shares can be designated as a Time Machine share with the following setting:
+ 'fruit:time machine = yes'
-Btrfs Filesystem Integration
-============================
+Support for lower casing the MDNS Name
+======================================
+Allows the server name that is advertised through MDNS to be set to the
+hostname rather than the Samba NETBIOS name. This allows an administrator
+to make Samba registered MDNS records match the case of the hostname
+rather than being in all capitals.
-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 can be set with the following settings:
-This feature can be explicitly enabled on smbd shares backed by a Btrfs
-filesystem with the smb.conf parameter:
-vfs objects = btrfs
+ 'mdns name = mdns'
-REMOVED COMPONENTS
-==================
+smb.conf changes
+================
-The Samba Web Administration Tool (SWAT) has been removed.
+ Parameter Name Description Default
+ -------------- ----------- -------
+ binddns dir New
+ gpo update command New
+ oplock contention limit Removed
+ prefork children New 1
+ mdns name Added netbios
+ fruit:time machine Added false
+NT4-style replication based net commands removed
+================================================
-######################################################################
-Changes
-#######
+The following commands and sub-commands have been removed from the
+"net" utility:
-smb.conf changes
-----------------
+net rpc samdump
+net rpc vampire ldif
- Parameter Name Description Default
- -------------- ----------- -------
+Also, replicating from a real NT4 domain with "net rpc vampire" and
+"net rpc vampire keytab" has been removed.
- password level Removed
- set directory Removed
- use ntdb New No
+The NT4-based commands were accidentially broken in 2013, and nobody
+noticed the breakage. So instead of fixing them including tests (which
+would have meant writing a server for the protocols, which we don't
+have) we decided to remove them.
+For the same reason, the "samsync", "samdeltas" and "database_redo"
+commands have been removed from rpcclient.
-CHANGES SINCE 4.0.7
-===================
+"net rpc vampire keytab" from Active Directory domains continues to be
+supported.
-o Michael Adam <obnox@samba.org>
+vfs_aio_linux module removed
+============================
+The current Linux kernel aio does not match what Samba would
+do. Shipping code that uses it leads people to false
+assumptions. Samba implements async I/O based on threads by default,
+there is no special module required to see benefits of read and write
+request being sent do the disk in parallel.
-KNOWN ISSUES
-============
+smbclient reparse point symlink parameters reversed
+===================================================
+
+A bug in smbclient caused the 'symlink' command to reverse the
+meaning of the new name and link target parameters when creating a
+reparse point symlink against a Windows server. As this is a
+little used feature the ordering of these parameters has been
+reversed to match the parameter ordering of the UNIX extensions
+'symlink' command. The usage message for this command has also
+been improved to remove confusion.
+
+REMOVED FEATURES
+================
+
+The two commands "net serverid list" and "net serverid wipe" have been
+removed, because the file serverid.tdb is not used anymore.
+"net serverid list" can be replaced by listing all files in the
+subdirectory "msg.lock" of Samba's "lock directory". The unique id
+listed by "net serverid list" is stored in every process' lockfile in
+"msg.lock".
-RUNNING Samba 4.1 as an AD DC
-=============================
+"net serverid wipe" is not necessary anymore. It was meant primarily
+for clustered environments, where the serverid.tdb file was not
+properly cleaned up after single node crashes. Nowadays smbd and
+winbind take care of cleaning up the msg.lock and msg.sock directories
+automatically.
