# For full coverage, we'd have to test all supported Python, MongoDB, and
# PyMongo combinations. However, that would result in an overly long build
# with a very large number of jobs, hence we only test a subset of all the
# combinations:
# * MongoDB v3.4 & the latest PyMongo v3.x is currently the "main" setup,
#   tested against Python v2.7, v3.5, v3.6, and PyPy.
# * Besides that, we test the lowest actively supported Python/MongoDB/PyMongo
#   combination: MongoDB v3.4, PyMongo v3.4, Python v2.7.
# * MongoDB v3.6 is tested against Python v3.6, and PyMongo v3.6, v3.7, v3.8.
#
# We should periodically check MongoDB Server versions supported by MongoDB
# Inc., add newly released versions to the test matrix, and remove versions
# which have reached their End of Life. See:
# 1. https://www.mongodb.com/support-policy.
# 2. https://docs.mongodb.com/ecosystem/drivers/driver-compatibility-reference/#python-driver-compatibility
#
# Reminder: Update README.rst if you change MongoDB versions we test.
