[willfarrell]

Update on the release of v7. Due to some major changes to lambda announced at re:invent, v7 will be delayed to allow time to understand what the new best practices are and how best they should be introduced into middy.

If you have thoughts on how middy should handle the new tenant isolation, managed instances, or the new context handling, please comment.
