"Today Oracle released Solaris 11 Express 2010.11. It includes a large number of new features (PDF) not found in either Oracle Solaris 10 or previous OpenSolaris releases, including ZFS encryption and deduplication, network-based packaging and provisioning systems, network virtualization, optimized I/O for NUMA platforms and optimized platform support including support for Intel's latest Nehalem and SPARC T3. In addition, Oracle Solaris 10 support is available from within a container/zone so migration of existing systems is greatly simplified."
Reader gtirloni adds, "Oracle also announced that this is not a beta or preview, but a full, supported release aimed at everybody developing, testing, prototyping or demonstrating applications running on the latest Solaris release (
not allowed to be used in production)."
