New update version for Solaris 10:

Solaris 10 11/06 is out
Relases notes

Thanks Toots for this info.

Update: Big feature, this release includes LDOM for T1000/T2000 cpu (Niagara T1)
Ldom is a kind of Xen for Solaris, the big problem with zones was that it needed to share the same routing instance (cause only one kernel runned), now with LDOM you can have seperate routing configuration on the same server.
