 > The changes noted within this `vNEXT` section have not been released yet.  New PRs and commits which introduce changes should include an entry in this `vNEXT` section as part of their development.  When a release is being prepared, a new header will be (manually) created below and the the appropriate changes within that release will be moved into the new section.
 
-- _Nothing yet! Stay tuned!_
+* Remove `apollo-env` dependency to eliminate circular dependency between the two packages. This circular dependency makes the tooling repo unpublishable when `apollo-env` requires a version bump. [#3463](https://github.com/apollographql/apollo-server/pull/3463)
