## Issue Addressed
NA
## Proposed Changes
Since we use the `rc` (release candidate) tag in our version strings, it seems consistent if we also use "release candidate" in the book rather than "pre-release".
Notably, Github adds a "pre-release" tag to release when we request. I think it's OK that Github uses that term whilst we consistently use "release candidate". Our docs indicate that the terms are interchangeable.
## Additional Info
I hope to use the new docs link in the `v2.1.0` release, so it would be nice if we can merge this soon 🙏
