+NEW FEATURES/CHANGES
+====================
+
+Using x86_64 Accelerated AES Crypto Instructions
+================================================
+
+Samba on x86_64 can now be configured to use the Intel accelerated AES
+instruction set, which has the potential to make SMB3 signing and
+encryption much faster on client and server. To enable this, configure
+Samba using the new option --accel-aes=intelaesni.
-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.
+This is a temporary solution that is being included to allow users
+to enjoy the benefits of Intel accelerated AES on the x86_64 platform,
+but the longer-term solution will be to move Samba to a fully supported
+external crypto library.
+The third_party/aesni-intel code will be removed from Samba as soon as
+external crypto library performance reaches parity.

+The default is to build without setting --accel-aes, which uses the
+existing Samba software AES implementation.
smb.conf changes
-----------------
+================

+ Parameter Name Description Default
+ -------------- ----------- -------
+ oplock contention limit Removed
+
+NT4-style replication based net commands removed
+================================================
- Parameter Name Description Default
- -------------- ----------- -------
- logging New (empty)
+The following commands and sub-commands have been removed from the
+"net" utility:
+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.
