What is the current behavior?

Issue Number: N/A
We moved to automated release scripts and no longer have a need for the old release scripts. Since we have done multiple successful releases with the new process, it seems safe to remove the old release process.

What is the new behavior?

• Remove old release scripts and associated dependencies

Does this introduce a breaking change?

• Yes
• No
