  update readme on release of next version
  suggest replacing
  
  ```**Supports:** python 2.7, 3.5, 3.6```
  
  with:
  
  ```[![PyPI pyversions](https://img.shields.io/pypi/pyversions/pandera.svg)](https://pypi.python.org/pypi/pandera/)```
  
  when the new metadata is available on pypi.
  
  It will be 'missing' before pypi is updated:
  [![PyPI pyversions](https://img.shields.io/pypi/pyversions/pandera.svg)](https://pypi.python.org/pypi/pandera/)
