Starting this week, we’ll be deploying a new default image for our documentation build environments. This image will change the default Python versions that are supported.
We aren’t expecting any issues to arise from this change, but be sure to raise
any issues on our issue tracker if you notice any strange behavior. The new
build image supports Python
2.7 and Python
3.5, dropping support for
3.4. If you require access to Python
3.4, we suggest you sign up
for access to our next beta image.
