-# Packages to install in the Python sandbox for secured execution of code provided by course authors.
-#
-# DON'T JUST ADD NEW DEPENDENCIES!!!
-#
-# If you open a pull request that adds a new dependency, you should:
-#   * verify that the dependency has a license compatible with AGPLv3
-#   * confirm that it has no system requirements beyond what we already install
-#   * run "make upgrade" to update the detailed requirements files
-
-
-# We pin things specifically in this file beacuse we want to be very explicit about
-# updating dependencies to the sandbox since they can impact how custom response code is run.
-# We can then use constraints.txt to constrain any sub-dependencies that may need to be held back.

-# This file has been frozen for the benefit of Python 2.7 sandboxes, and
-# "make upgrade" no longer updates it.  It can be removed once that
-# version of the sandbox is no longer run in production.  Before removal,
-# the configuration repository needs to be updated to use the new file:
-# https://github.com/edx/configuration/blob/master/playbooks/roles/edxapp/defaults/main.yml#L1628
-# Also, this change needs to be announced and communicated to partners
