Uwe L. Korn commented on ARROW-2783:
------------------------------------
Should be fixed now again, will finish the migration with the
{{pyarrow-feedstock}} now but the chain hopefully works again. Their automated
bot changes sadly introduced some silent breakages due to the new way of
pinning package versions and specifying windows support. Sadly as always with
conda-forge, builds are stuck in a long queue in Travis.
