v20.0.24 (2020-06-22)

Features - 20.0.24

- Ensure that the seeded packages do not get too much out of date:

add a CLI flag that triggers upgrade of embedded wheels under :option:upgrade-embed-wheels
periodically (once every 14 days) upgrade the embedded wheels in a background process, and use them if they have been
released for more than 28 days (can be disabled via :option:no-periodic-update)

ship wheels for Python 3.9 and 3.10
