UPGRADING
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.
-
-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.
-
-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).
-
-Adds the samba_gpoupdate script for applying and unapplying
-policy. Can be applied automatically by setting
+Default samba process model
+---------------------------
+
+The default for the --model argument passed to the samba executable has changed
+from 'standard' to 'prefork'. This means a difference in the number of samba
+child processes that are created to handle client connections. The previous
+default would create a separate process for every LDAP or NETLOGON client
+connection. For a network with a lot of persistent client connections, this
+could result in significant memory overhead. Now, with the new default of
+'prefork', the LDAP, NETLOGON, and KDC services will create a fixed number of
+worker processes at startup and share the client connections amongst these
+workers. The number of worker processes can be configured by the 'prefork
+children' setting in the smb.conf (the default is 4).

+REMOVED FEATURES
+================
- 'server services = +gpoupdate'.
smb.conf changes
================
- Parameter Name Description Default
- -------------- ----------- -------
- oplock contention limit Removed
-
-NT4-style replication based net commands removed
-================================================
-
-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.
-
-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
-===================================================
+ Parameter Name Description Default
+ -------------- ----------- -------
-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.
