Thread:Extension talk:VisualEditor/Parity in versions with Parsoid (and node.js)

Could someone help clarify the dependency and versioning between VisualEditor and Parsoid? If a new build of VisualEditor is available (such as the release on June 6) does it require an updated build of Parsoid as well? Do these two inter-related projects require a lock-step update process? The requirements are a little fuzzy to me. (I could be looking in the wrong location as well).
