Code for most recent stable release

Please link me to the code version for the most recent stable release, I had issues trying to run my fork in Python. ... Also, where is the serverside code for the referring URLs?

No file, test, or entry point is named. First identify the most recent stable release code and locate the server-side implementation for referring URLs; done when both locations are clearly documented for users running a fork.
