Comments on conflicts:
- llvm: d6f401e1 vs. 469ecc70 - docs for 6 and 7 say the default is
to build all targets, so we should be fine
- some pypi hashes: they were equivalent, just base16 vs. base32
Changelog:
https://cryptography.io/en/latest/changelog/#v2-4-2
Important changes:
- BACKWARDS INCOMPATIBLE: Dropped support for LibreSSL 2.4.x.
- Deprecated OpenSSL 1.0.1 support. OpenSSL 1.0.1 is no longer supported
by the OpenSSL project. At this time there is no time table for
dropping support, however we strongly encourage all users to upgrade
or install cryptography from a wheel.
