+# that could start rejecting our code.
+# 2.4.4 is the version in Ubuntu 20.04. It supports Python >=3.5.
+pylint == 2.4.4
+
+# Use the earliest version of mypy that works with our code base.
+# See https://github.com/Mbed-TLS/mbedtls/pull/3953 .

+# At the time of writing, only needed for tests/scripts/audit-validity-dates.py.
+# It needs >=35.0.0 for correct operation, and that requires Python >=3.6,
+# but our CI has Python 3.5. So let pip install the newest version that's
+# compatible with the running Python: this way we get something good enough
+# for mypy and pylint under Python 3.5, and we also get something good enough
+# to run audit-validity-dates.py on Python >=3.6.
+cryptography # >= 35.0.0
