z/VM Continuous Delivery News

z/VM Development maintains a z/VM Continuous Delivery News web page that describes the various enhancements for z/VM, both the ones in progress and the ones they have shipped. This essentially replaced most of what was done via announce letters in the past. You will find some items that they are just starting to consider as candidates as well as those in various phases of engagement with Sponsor Users. It changes multiple times per quarter so if it interests you, consider being on the notification list by clicking the "Notify me" link on the left hand navigation bar.
