Customers running the 1.3 code version should be aware that 1.3.0.10 is the last planned release for the 1.3 code stream and that it will no longer be supported from a security fix point of view going forward. These customers should consider upgrading to either 1.4.8.0 or 1.5.1.1 to pick up these security fixes in these newer code streams which will continue to be supported.
