What is ffxiv 7.0?

As an AI language model, I don't have access to any future information. However, as of September 2021, the latest expansion for Final Fantasy XIV is Endwalker, which will be released on November 23, 2021. It features new zones, quests, classes, storylines, and more. The level cap has been raised to 90, and it marks the conclusion of the current storyline. Square Enix, the developer of FFXIV, has not yet announced any plans for version 7.0 at this time.
