v3.2.1

Added:

• Added support for rendering feedstock recipes for Azure pipelines.
  Presently this is enabled globally for all feedstocks going forward by default.
  Azure builds are configured to not publish artifacts to anaconda.org
• PR template asking for news entries
  (aka, I heard you like news, so I put a news item about adding news items into
  your news item, so you can add news while you add news)
• Feedstock maintainers are now listed in the README file.

Removed:

• Python 2.7 support has been dropped. Conda-smithy now requires python >= 3.5.

Fixed:

• Fixes issue with Circle job definition where "filters are incompatible with
  workflows" when Linux is skipped. This was causing Linux jobs to be created
  and then fail on feedstocks where Linux and Circle were not needed.
