As a C extension supporting many platforms, each release of
the grpcio PyPi project currently takes up over 1 GB. This has previously led to the project hitting its storage ceiling. To combat this issue, going forward,
grpcio will begin deleting its PyPi prereleases older than 1 year.
Please reach out within the next week if you have any concerns with this new policy.
Thanks,
