VMware has released a new version of NSX-v, the NSX edition for vSphere environment. Note that NSX 6.4 is a new minor release, but has so many important enhancements, new features, and improvements that can be considered a new major release. The most interesting news are the support to the HTML5 vSphere Client (another little step to a complete adoption) and some new interesting features and capabilità in the distributed firewall. For more technical details on the new features, see this post.
