UPGRADING
NEW FEATURES/CHANGES
====================
-Authentication and Authorization audit support
-----------------------------------------------
-
-Detailed authentication and authorization audit information is now
-logged to Samba's debug logs under the "auth_audit" debug class,
-including in particular the client IP address triggering the audit
-line. Additionally, if Samba is compiled against the jansson JSON
-library, a JSON representation is logged under the "auth_json_audit"
-debug class.
-
-Audit support is comprehensive for all authentication and
-authorisation of user accounts in the Samba Active Directory Domain
-Controller, as well as the implicit authentication in password
-changes. In the file server and classic/NT4 domain controller, NTLM
-authentication, SMB and RPC authorization is covered, however password
-changes are not at this stage, and this support is not currently
-backed by a testsuite.
-
-Parameter changes
------------------
-
-The "strict sync" global parameter has been changed from
-a default of "no" to "yes". This means smbd will by default
-obey client requests to synchronize unwritten data in operating
-system buffers safely onto disk. This is a safer default setting
-for modern SMB1/2/3 clients.
-
-smb.conf changes
+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
================
- Parameter Name Description Default
- -------------- ----------- -------
- auth event notification New parameter no
- auth methods Deprecated
- map untrusted to domain Deprecated
- strict sync Default changed yes
-
-Removal of lpcfg_register_defaults_hook()
------------------------------------------
-
-The undocumented and unsupported function lpcfg_register_defaults_hook()
-that was used by external projects to call into Samba and modify
-smb.conf default parameter settings has been removed. If your project
-was using this call please raise the issue on
-samba-technical@lists.samba.org in order to design a supported
-way of obtaining the same functionality.
-
-Change of loadable module interface
------------------------------------
-The _init function of all loadable modules in Samba has changed
-from:
-
-NTSTATUS _init(void);
-
-to:
+smb.conf changes
+================
-NTSTATUS _init(TALLOC_CTX *);
+ Parameter Name Description Default
+ -------------- ----------- -------
-This allows a program loading a module to pass in a long-lived
-talloc context (which must be guaranteed to be alive for the
-lifetime of the module). This allows modules to avoid use of
-the talloc_autofree_context() (which is inherently thread-unsafe)
-and still be valgrind-clean on exit. Modules that don't need to
-free long-lived data on exist should use the NULL talloc context.
