VIRTUALIZATION, IN COMPUTING, REFERS TO THE ACT OF CREATING A VIRTUAL VERSION OF SOMETHING, INCLUDING BUT NOT LIMITED TO A VIRTUAL COMPUTER HARDWARE PLATFORM, OPERATING SYSTEM (OS), STORAGE DEVICE, OR COMPUTER NETWORK RESOURCES.
Back in July of 2016, VMware issued a Field Advisory, announcing bugs for the release of NSX for vSphere 6.2.3. VMware urged its user community, not to upgrade to this version and if you had they came out with a 6.2.3.a release to resolve the issues. The issues that VMware found were that both primary and secondary HA nodes would be placed into Active State, causing network disruption and issues related to the DFW rules causing traffic disruptions.
VMware has now released, back in August, the new version 6.2.4 for GA. This release includes some critical bug fixes previously identified which includes a critical input validation vulnerability for sites that use NSX SSL VPN. You can see the full list what's new in the release notes.
Most of the new features were already discussed by me in a previous post you can find here. In this new version the only thing listed as new is a new feature around "Firewall Status API".
VMware also has announced the End of Availability (EOA) and End of General Support (EOGS) for Cloud Networking and Security 5.5.x. The date is September 19, 2016 for both.
