samba-tool domain backup --no-secrets avoids confidential attributes
--------------------------------------------------------------------

The --no-secrets option creates a back-up without secret attributes
(e.g. passwords), suitable for use in a lab domain. Until now it could
still contain confidential attributes, including BitLocker recovery
data and KDS root keys. Objects in the classes msKds-ProvRootKey,
msFVE-RecoveryInformation, and msTPM-InformationObject will now be
entirely removed from the backup, as these objects are required by
schema to have confidential attributes and are no use without them.

CTDB changes
------------

* CTDB now supports loading tunables from
 ? /etc/ctdb/tunables.d/*.tunables, in addition to the standard
 ? /etc/ctdb/tunables.conf.? See the ctdb-tunables(7) manual page for
 ? more details.? Note that the above locations are examples - the
 ? actual location of these files will depend on compile time
 ? configuration.

 ? It isn't expected that many users will require a directory of tunables
 ? files, since most users do not need to change tunables from their
 ? default values.? However, this allows vendors to ship their required
 ? tunables settings (for example, in one or more files marked "do not
 ? edit") while still allowing local administrators to add their own
 ? tunables settings (in one or more separate files).

Per-share profiling stats
-------------------------
Starting with Samba 4.23, users can collect profile counters at a
per-share level. This feature requires building Samba with profiling
data enabled and adding an appropriate `smb.conf` parameter for
specific shares. It's particularly useful for deployments with a large
number of active shares, allowing administrators to monitor individual
share activity and identify potential bottlenecks or hot-spots. When
enabled, users can inspect current per-share profile information
("Extended Profile") using the standard `smbstatus` utility.

Currently, this functionality is supported only by the default and
`ceph_new` VFS modules.
