Scala 3.0.0-M3: developer's preview before RC1

It is intended to contain all the features meant for RC1, which is tentatively planned for January 2021. The purpose of M3 is to give the larger community, beyond early adopters, a chance to try out all the features and give us feedback before sealing them in RC1.

This library aims to provide easy integration with OAuth2 providers based on OAuth2 RFC using sttp client. It uses circe for JSON serialization/deserialization.

cats-effect v3.0.0-M5

We are expecting to follow this milestone with subsequent ones as necessary to further refine functionality and features, prior to some number of release candidates leading to a final release. The designation "M5" is meant to indicate our relative confidence in the functionality and API of the library, but it by no means indicates completeness or final compatibility. Neither binary compatibility nor source compatibility with anything are assured prior to 3.0.0, though major breakage is unlikely at this point.
