(The administrator needs to correct the values of XML entities between
the backup and restore to account for the change in domain).
+kdc prefork
+-----------
+
+The KDC now supports the pre-fork process model and worker processes will be
+forked for the KDC when the pre-fork process model is selected for samba.
+
+prefork 'prefork children'
+--------------------------
+
+The default value for this smdb.conf parameter has been increased from 1 to
+4.
+
+netlogon prefork
+----------------
+
+DCERPC now supports pre-forked NETLOGON processes. The netlogon processes are
+pre-forked when the prefork process model is selected for samba.
+
+Offline domain backups
+----------------------
+
+The 'samba-tool domain backup' command has been extended with a new 'offline'
+option. This safely creates a backup of the local DC's database directly from
+disk. The main benefits of an offline backup are it's quicker, it stores more
+database details (for forensic purposes), and the samba process does not have
+to be running when the backup is made. Refer to the samba-tool help for more
+details on using this command.
+
+Group membership statistics
+---------------------------
+
+A new 'samba-tool group stats' command has been added. This provides summary
+information about how the users are spread across groups in your domain.
+The 'samba-tool group list --verbose' command has also been updated to include
+the number of users in each group.
+
+prefork process restart
+-----------------------
+
+The pre-fork process model now restarts failed processes. The delay between
+restart attempts is controlled by the "prefork backoff increment" (default = 10)
+and "prefork maximum backoff" (default = 120) smbd.conf parameters. A linear
+back off strategy is used with "prefork backoff increment" added to the
+delay between restart attempts up until it reaches "prefork maximum backoff".
+
+Using the default sequence the restart delays (in seconds) are:
+ 0, 10, 20, ..., 120, 120, ...
+
+standard process model
+----------------------
+
+When using the standard process model samba forks a new process to handle ldap
+and netlogon connections. Samba now honours the 'max smbd processes' smb.conf
+parameter. The default value of 0, indicates there is no limit. The limit
+is applied individually to netlogon and ldap. When the process limit is
+exceeded Samba drops new connections immediately.
+
+python3 support
+---------------
+
+The version of python which is now the default for samba is python3.
+'configure' & 'make' will execute using python3. It is possible to still
+specify an additional python version with '--extra-python'
+e.g. '--extra-python=/usr/bin/python2'. It should be noted that support for
+this option will be deprecated in a future release.
+
+What if I need to build with python2? To build with python2 you *must* set
+the 'PYTHON' environent variable to override the python3 default for both
+'configure' and 'make' steps.
+
+ 'PYTHON=python2 ./configure.developer'
+&
+ 'PYTHON=python2 make'
+
+Note: Support for python2 (with the exception of a build configured with
+ 'PYTHON=python2 ./configure --disable-python' and built with
+ 'PYTHON=python2 make' will be deprecated in the next release.
+
+JSON logging
+------------
+
+Authentication messages now contain the Windows Event Id "eventId" and logon
+type "logonType". The supported event codes and logon types are:
+ Event codes:
+ 4624 Successful logon
+ 4625 Unsuccessful logon
+
+ Logon Types:
+ 2 Interactive
+ 3 Network
+ 8 NetworkCleartext
+
+The version number for Authentication messages is now 1.1, changed from 1.0
+
+Password change messages now contain the Windows Event Id "eventId", the
+supported event Id's are:
+ 4723 Password changed
+ 4724 Password reset
+
+The version number for PasswordChange messages is now 1.1, changed from 1.0
+
+Group membership change messages now contain the Windows Event Id "eventId",
+the supported event Id's are:
+ 4728 A member was added to a security enabled global group
+ 4729 A member was removed from a security enabled global group
+ 4732 A member was added to a security enabled local group
+ 4733 A member was removed from a security enabled local group
+ 4746 A member was added to a security disabled local group
+ 4747 A member was removed from a security disabled local group
+ 4751 A member was added to a security disabled global group
+ 4752 A member was removed from a security disabled global group
+ 4756 A member was added to a security enabled universal group
+ 4757 A member was removed from a security enabled universal group
+ 4761 A member was added to a security disabled universal group
+ 4762 A member was removed from a security disabled universal group
+
+
+The version number for GroupChange messages is now 1.1, changed from 1.0. Also
+A GroupChange message is generated when a new user is created to log that the
+user has been added to their primary group.
+
+The leading "JSON <message type>:" and source file prefix of the JSON formatted
+log entries has been removed to make the parsing of the JSON log messages
+easier. JSON log entries now start with 2 spaces followed by an opening brace
+i.e. " {"
+
+

REMOVED FEATURES
================
+MIT Kerberos build of the AD DC
+-------------------------------
+
+While not removed, the MIT Kerberos build of the Samba AD DC is still
+considered experimental. Because Samba will not issue security
+patches for this configuration, such builds now require the explicit
+configure option: --with-experimental-mit-ad-dc
+
+For further details see
+https://wiki.samba.org/index.php/Running_a_Samba_AD_DC_with_MIT_Kerberos_KDC
+
+samba_backup
+------------
+
+The samba_backup script has been removed. This has now been replaced by the
+'samba-tool domain backup offline' command.
