+Samba4 alpha11 is not a final Samba release. That is more a reference
to Samba4's lack of the features we expect you will need than a
statement of code quality, but clearly it hasn't seen a broad
deployment yet. If you were to upgrade Samba3 (or indeed Windows) to
Samba4, you would find many things work, but that other key features
you may have relied on simply are not there yet.

Directory domain, Samba4 is happier as a domain controller, and it is
in this role where it has seen deployment into production.
We are aiming for Samba 4 to be powerful frontend to large
directories.
-CHANGES SINCE Alpha5
+CHANGES SINCE alpha10
=====================
-In the time since Samba4 Alpha5 was released in June 2008, Samba has
-continued to evolve, but you may particularly notice these areas:
+Since the alpha10 release, we have fixed a number of serious bugs in
+the implementation of AD-compatible 'Directory Replication Services'.
+We can now join an AD domain as a read-write DC
- The source code for various libraries that are used by both Samba 3 and
- Samba 4 are now shared between the two rather than duplicated
- (and being slightly diverged).
+Importantly, since alpha10, the following serious issues were
+addressed:
+ - We now allocate RID values safely (previous implementations would
+ add users and groups without regard to allocated RID pools, possibly
+ creating duplicates)
+ - In previous Samba4 versions, a failure to 'prepare' a transaction
+ would silently commit the transaction.
-These are just some of the highlights of the work done in the past few
-months. More details can be found in our GIT history.
+Any deployments of Samba4 before this alpha are very strongly
+encouraged to upgrade. Assistance may be found in the
+upgradeprovision script, and the advice of the Samba Team should be
+sought to determine the impact of these issues in your particular
+deployment.
+Our progress on DRS is being tracked in the Samba wiki:

CHANGES
=======
- Clock Synchronisation is critical. Many 'wrong password' errors are
actually due to Kerberos objecting to a clock skew between client

with this problem).
-- Samba4 alpha6 is currently only portable to recent Linux
- distributions. Work to return support for other Unix varients is
- expected during the next alpha cycle
+- The DRS replication code often fails, and is very new
-- Samba4 alpha6 is incompatible with GnuTLS 2.0, found in Fedora 9 and
- recent Ubuntu releases. GnuTLS use may be disabled using the
- --disable-gnutls argument to ./configure. (otherwise 'make test' and
- LDAPS operations will hang).
+- Users upgrading existing databases to Samba4 should carefully
+ consult upgrading-samba4.txt. We have made a number of changes in
+ this release that should make it easier to upgrade in future.
+ Btw: there exists also a script under the "setup" directory of the
+ source distribution called "upgrade_from_s3" which should allow a step-up
+ from Samba3 to Samba4. It's not included yet in the binary distributions
+ since it's completely experimental!
+
+- ACL are not set by default on shares created by the provision.
+ Work is underway on this subject and it should be fixed in Alpha12.
