Deprecation notice for Python 3.5

As we start building out more of the python 3.7 stack, we will no longer be building python 3.5 packages.

No new python 3.5 packages will be built after 2018-10-01.


The compiler migration is in full swing. The bot will be making the rounds and modernizing more than 4000 packages. This is going to take a few months to get done so bear with us.



The rebuild is moving along nicely with almost a third of packages completed.

Recently completed are numpy and openblas which should open up much of the python numeric stack. We’re only about 5 feedstocks away from opening up all of R as well.


A minimal python 3.7 build is now available across all platforms and both compilers!


Conda forge now has a magical status bar for tracking the progress of migrations.
