-------------------
- Just a little defensive programming so that we don't break status actions

-------------------
- Refactor expansion methods
- Renaming to differentiate expansion_config init v.s. expansions from request
- When make request, the `body` takes `[value]` instead of `value`, assuming we always call batch endpoints
- When expand, the initial `exp_service_requests` set to empty, because the upstream `service` has been called before this method.

-------------------
- Bump Conformity and remove duplicate msgpack-python dependency
- Add support for auto-reloading code changes in dev environments
- Use Invoke Release for releases going forward
- Fix bug causing response mix-ups with transport cache
- Add ability to fork multiple server processes with the standalone command
- Start request counter at a random value (50)
- Add .pytest_cache to .gitignore
- Remove mock of randint
- Improve status action to enable abbreviated responses when only the version is needed
- Tweak comment

-------------------
- Ensure double-import trap doesn't catch entrypoint execution

-------------------
- Remove duplicate serialization from the server now that clients are no longer requesting serialization
- Bump Attrs, Conformity, and PyTest
- Add standalone helpers to eliminate lots of boilerplace code across services
- Fix a documentation typo

-------------------
- Attempt two at removing duplicate serialization from the client now that ASGI (incompatible) is removed
