Release Announcements
=====================

This is the first pre release of Samba 4.25.  This is *not*
intended for production environments and is designed for testing
purposes only.  Please report any defects via the Samba bug reporting
system at https://bugzilla.samba.org/.

Samba 4.25 will be the next version of the Samba suite.


UPGRADING
=========


NEW FEATURES/CHANGES
====================

JSON Audit logging
------------------

The two leading spaces before the opening '{' on JSON audit log lines have been
removed. And any embedded new line characters '\n' are converted to spaces.

Domain encryption types changed to AES by default
-------------------------------------------------

The default value of the smb.conf option ‘kdc default domain supported enctypes’
now corresponds to ‘aes128-cts-hmac-sha1-96 aes256-cts-hmac-sha1-96’ (both AES
encryption types) if the domain functional level is 2008 or higher. This
addresses CVE-2026-20833.

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

* CTDB's locations for locks, PID files and sockets now use ctdb/
  subdirectories of the Samba locations configured at build time.
  This means that the relevant top-level Samba configure options
  (--with-lockdir, --with-piddir, --with-sockets-dir) are now also
  used by CTDB.

  The standalone CTDB build does not support these options.  However,
  it is generally only used for developer/standalone testing.

* The CTDB initscript (ctdb.init) has been moved to ctdb/doc/examples.
  This recognises that it isn't installed by default so it is
  basically unmaintained and untested.

* Monitoring of (infrastructure) hosts is now supported.  A good use
  of this is to monitor DNS servers.  See the NETWORK MONITORING
  section in ctdb-script.options(5) for more details.

* The detect_init_style() script function and associated
  CTDB_INIT_STYLE variable are deprecated, so will be removed in a
  future release.  Use the new, more general CTDB_PLATFORM_STYLE
  variable instead.  This may affect site-local CTDB (event) scripts.
  See ctdb.sysconfig(5) for more details.
