NEW FEATURES/CHANGES
====================
-Here is a copy of a clarification note added to the Samba code
-in the file: VFS-License-clarification.txt.
---------------------------------------------------------------
-
-A clarification of our GNU GPL License enforcement boundary within the Samba
-Virtual File System (VFS) layer.
-
-Samba is licensed under the GNU GPL. All code committed to the Samba
-project or that creates a "modified version" or software "based on" Samba must
-be either licensed under the GNU GPL or a compatible license.
-
-Samba has several plug-in interfaces where external code may be called
-from Samba GNU GPL licensed code. The most important of these is the
-Samba VFS layer.
-
-Samba VFS modules are intimately connected by header files and API
-definitions to the part of the Samba code that provides file services,
-and as such, code that implements a plug-in Samba VFS module must be
-licensed under the GNU GPL or a compatible license.
-
-However, Samba VFS modules may themselves call third-party external
-libraries that are not part of the Samba project and are externally
-developed and maintained.
-
-As long as these third-party external libraries do not use any of the
-Samba internal structure, APIs or interface definitions created by the
-Samba project (to the extent that they would be considered subject to the GNU
-GPL), then the Samba Team will not consider such third-party external
-libraries called from Samba VFS modules as "based on" and/or creating a
-"modified version" of the Samba code for the purposes of GNU GPL.
-Accordingly, we do not require such libraries be licensed under the GNU GPL
-or a GNU GPL compatible license.
-
-VFS
----
-
-The effort to modernize Samba's VFS interface has reached a major milestone with
-the next release Samba 4.14.
-
-For details please refer to the documentation at source3/modules/The_New_VFS.txt or
-visit the <https://wiki.samba.org/index.php/The_New_VFS>.
-
-Printing
---------
-
-Publishing printers in AD is more reliable and more printer features are
-added to the published information in AD. Samba now also supports Windows
-drivers for the ARM64 architecture.
-
-
-Client Group Policy
--------------------
-This release extends Samba to support Group Policy functionality for Winbind
-clients. Active Directory Administrators can set policies that apply Sudoers
-configuration, and cron jobs to run hourly, daily, weekly or monthly.
+LDB no longer a standalone tarball
+----------------------------------
-To enable the application of Group Policies on a client, set the global
-smb.conf option 'apply group policies' to 'yes'. Policies are applied on an
-interval of every 90 minutes, plus a random offset between 0 and 30 minutes.
+LDB, Samba's LDAP-like local database and the power behind the Samba
+AD DC, is no longer available to build as a distinct tarball, but is
+instead provided as an optional public library.
-Policies applied by Samba are 'non-tattooing', meaning that changes can be
-reverted by executing the `samba-gpupdate --unapply` command. Policies can be
-re-applied using the `samba-gpupdate --force` command.
-To view what policies have been or will be applied to a system, use the
-`samba-gpupdate --rsop` command.
+If you need ldb as a public library, say to build sssd, then use
+ ./configure --private-libraries='!ldb'
-Administration of Samba policy requires that a Samba ADMX template be uploaded
-to the SYSVOL share. The samba-tool command `samba-tool gpo admxload` is
-provided as a convenient method for adding this policy. Once uploaded, policies
-can be modified in the Group Policy Management Editor under Computer
-Configuration/Policies/Administrative Templates. Alternatively, Samba policy
-may be managed using the `samba-tool gpo manage` command. This tool does not
-require the admx templates to be installed.
+This re-integration allows LDB tests to use the Samba's full selftest
+system, including our knownfail infrastructure, and decreases the work
+required during security releases as a coordinated release of the ldb
+tarball is not also required.
+This approach has been demonstrated already in Debian, which is already
+building Samba and LDB is this way.
-Python 3.6 or later required
-----------------------------
+As part of this work, the pyldb-util public library, not known to be
+used by any other software, is made private to Samba.
-Samba's minimum runtime requirement for python was raised to Python
-3.6 with samba 4.13. Samba 4.14 raises this minimum version to Python
-3.6 also to build Samba. It is no longer possible to build Samba
-(even just the file server) with Python versions 2.6 and 2.7.
-
-As Python 2.7 has been End Of Life upstream since April 2020, Samba
-is dropping ALL Python 2.x support in this release.
-
-
-NT4-like 'classic' Samba domain controllers
--------------------------------------------
-
-Samba 4.13 deprecates Samba's original domain controller mode.
-
-Sites using Samba as a Domain Controller should upgrade from the
-NT4-like 'classic' Domain Controller to a Samba Active Directory DC
-to ensure full operation with modern windows clients.
-
-
-SMBv1 only protocol options deprecated
+LDB Module API Python bindings removed
--------------------------------------
-A number of smb.conf parameters for less-secure authentication methods
-which are only possible over SMBv1 are deprecated in this release.
-
-
-Miscellaneous samba-tool changes
---------------------------------
-
-The samba-tool commands to manage AD objects (e.g. users, computers and
-groups) now consistently use the "add" command when adding a new object to
-the AD. The previous deprecation warnings when using the "add" commands
-have been removed. For compatibility reasons, both the "add" and "create"
-commands can be used now.
-
-Users, groups and contacts can now be renamed with the respective rename
-commands.
-
-Locked users can be unlocked with the new "samba-tool user unlock" command.
-
-The "samba-tool user list" and "samba-tool group listmembers" commands
-provide additional options to hide expired and disabled user accounts
-(--hide-expired and --hide-disabled).
-
-
-CTDB CHANGES
-============
-
-* The NAT gateway and LVS features now uses the term "leader" to refer
- to the main node in a group through which traffic is routed and
- "follower" for other members of a group. The command for
- determining the leader has changed to "ctdb natgw leader" (from
- "ctdb natgw master"). The configuration keyword for indicating that
- a node can not be the leader of a group has changed to
- "follower-only" (from "slave-only"). Identical changes were made
- for LVS.
-
-* Remove "ctdb isnotrecmaster" command. It isn't used by CTDB's
- scripts and can be checked by users with "ctdb pnn" and "ctdb
- recmaster".
-
+The LDB Modules API, which we do not promise a stable ABI or API for,
+was wrapped in python in early LDB development. However that wrapping
+never took into account later changes, and so has not worked for a
+number of years. Samba 4.21 and LDB 2.10 removes this unused and
+broken feature.
