Release Announcements
=====================
This is the first preview release of Samba 4.12. 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 4.12 will be the next version of the Samba suite.
UPGRADING
=========
NEW FEATURES/CHANGES
====================
Python 3.5 Required
-------------------
Samba's minimum runtime requirement for python was raised to Python
3.4 with samba 4.11. Samba 4.12 raises this minimum version to Python
3.5 both to access new features and because this is the oldest version
we test with in our CI infrastructure.
(Build time support for the file server with Python 2.6 has not
changed)
GnuTLS 3.4.7 required
---------------------
Samba is making efforts to remove in-tree cryptographic functionality,
and to instead rely on externally maintained libraries. To this end,
Samba has chosen GnuTLS as our standard cryptographic provider.
Samba now requires GnuTLS 3.4.7 to be installed (including development
headers at build time) for all configurations, not just the Samba AD
DC.
NOTE WELL: The use of GnuTLS means that Samba will honour the
system-wide 'FIPS mode' (a reference to the US FIPS-140 cryptographic
standard) and so will not operate in many still common situations if
this system-wide parameter is in effect, as many of our protocols rely
on outdated cryptography.
A future Samba version will mitigate this to some extent where good
cryptography effectively wraps bad cryptography, but for now that above
applies.
REMOVED FEATURES
================
BIND9_FLATFILE deprecated
-------------------------
The BIND9_FLATFILE DNS backend is deprecated in this release and will
be removed in the future. This was only practically useful on a single
domain controller or under expert care and supervision.
This release removes the "rndc command" smb.conf parameter, which
supported this configuration by writing out a list of DCs permitted to
make changes to the DNS Zone and nudging the 'named' server if a new
DC was added to the domain. Administrators using BIND9_FLATFILE will
need to maintain this manually from now on.
smb.conf changes
================
Parameter Name Description Default
-------------- ----------- -------
nfs4:acedup Changed default merge
rndc command Removed

Reporting bugs & Development Discussion
#######################################
Please discuss this release on the samba-technical mailing list or by
joining the #samba-technical IRC channel on irc.freenode.net.
If you do report problems then please try to send high quality
feedback. If you don't provide vital information to help us track down
the problem then you will probably be ignored. All bug reports should
be filed under the Samba 4.1 and newer product in the project's Bugzilla
database (https://bugzilla.samba.org/).
