UPGRADING
NEW FEATURES/CHANGES
====================
-Using x86_64 Accelerated AES Crypto Instructions
-================================================
+Default samba process model
+---------------------------
-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 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).
-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.
+Authentication Logging.
+-----------------------
-The third_party/aesni-intel code will be removed from Samba as soon as
-external crypto library performance reaches parity.
+Winbind now logs PAM_AUTH and NTLM_AUTH events, a new attribute "logonId" has
+been added to the Authentication JSON log messages. This contains a random
+logon id that is generated for each PAM_AUTH and NTLM_AUTH request and is passed
+to SamLogon, linking the windbind and SamLogon requests.
+
+The serviceDescription of the messages is set to "winbind", the authDescription
+is set to one of:
+ "PASSDB, <command>, <pid>"
+ "PAM_AUTH, <command>, <pid>"
+ "NTLM_AUTH, <command>, <pid>"
+where:
+ <command> is the name of the command makinmg the winbind request i.e. wbinfo
+ <pid> is the process id of the requesting process.
+
+The version of the JSON Authentication messages has been changed to 1.2 from 1.1

+REMOVED FEATURES
+================
+
+Web server
+----------
+
+As a leftover from work related to the Samba Web Administration Tool (SWAT),
+Samba still supported a Python WSGI web server (which could still be turned on
+from the 'server services' smb.conf parameter). This service was unused and has
+now been removed from Samba.
-The default is to build without setting --accel-aes, which uses the
-existing Samba software AES implementation.
