repository - Why is python 3.6.1. not available in pyenv?

Question

According to python.org, Python 3.6.1 was released at the end of March. But:

? pyenv install -l | grep 3.6.
  3.6.0a1
  3.6.0a3
  3.6-dev

1. Why is Python 3.6.1 not yet available in pyenv?
2. Where can I find documentation about the releases that pyenv supports? (when it was added, what is in progress, ...). The pyenv documentation does not give this information.
3. Is there a repository for Python releases supported by pyenv? (similar to PyPi)
