-Samba4 alpha4 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.
+Samba4 alpha17 is not a final Samba release, however we are now making
+good progress towards a Samba 4.0 release, of which this is a preview.
+Be aware the this release contains both the technology of Samba 3.6
+(that you can reasonably expect to upgrade existing Samba 3.x releases
+to) and the AD domain controller work previously known as 'samba4'.
+
+While binaries for the stable file server are provided in this
+release, for a stable, supported file server, Samba3 domain or AD
+domain member installation, please run a Samba 3.x release, as we are
+still bedding down the new single build system.
