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.


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>.


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.

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.

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.

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.

Python 3.6 or later required

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.

Miscellaneous samba-tool changes

The 'samba-tool' subcommands 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

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).


* 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
