NEW FEATURES/CHANGES
====================
-REMOVED FEATURES
-================
+KDC GPO application
+-------------------
+
+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).
-only user and username parameters
----------------------------------
-These two parameters have long been deprecated and superseded by
-"valid users" and "invalid users".
+Adds the samba_gpoupdate script for applying and unapplying
+policy. Can be applied automatically by setting
+
+ 'server services = +gpoupdate'.
smb.conf changes
-----------------
+================
+
+ Parameter Name Description Default
+ -------------- ----------- -------
+ binddns dir New
+ gpo update command New
+ oplock contention limit Removed
+ prefork children New 1
+
+
+NT4-style replication based net commands removed
+================================================
+
+The following commands and sub-commands have been removed from the
+"net" utility:
- Parameter Name Description Default
- -------------- ----------- -------
- only user Removed
- username Removed
+net rpc samdump
+net rpc vampire ldif
+
+Also, replicating from a real NT4 domain with "net rpc vampire" and
+"net rpc vampire keytab" has been removed.
+
+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.
+
+"net rpc vampire keytab" from Active Directory domains continues to be
+supported.
+
+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.
+
+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.
