UPGRADING
NEW FEATURES/CHANGES
====================
-GPO Improvements
-----------------
+Python 3.5 Required
+-------------------
-A new 'samba-tool gpo export' command has been added that can export a
-set of Group Policy Objects from a domain in a generalised XML format.
+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.
-A corresponding 'samba-tool gpo restore' command has been added to
-rebuild the Group Policy Objects from the XML after generalization.
-(The administrator needs to correct the values of XML entities between
-the backup and restore to account for the change in domain).
+(Build time support for the file server with Python 2.6 has not
+changed)
-kdc prefork
------------
+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+on outdated cryptography.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.
-The KDC now supports the pre-fork process model and worker processes will be
-forked for the KDC when the pre-fork process model is selected for samba.
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.
