Existential Crisis: Implementing MapK in Scala 3

This a record of my attempts to migrate one of my favourite types, MapK, from Scala 2 to Scala 3. You'll learn why this is not a trivial task and how to work around the new limitations. Hopefully this will help you solve similar problems with other types as well.

RELEASES

validated

Companion to the Scala std lib, providing useful subtypes like `PositiveInt` or `MatchesRegex` as well as the ability to define custom validations.
Tamer Abdulradi (@tabdulradi)
caliban 1.0.0

Caliban has been reliable and stable for a long while now, and the few bugs that have been discovered in the recent past were about minor edge cases and immediately fixed. Most of the changes are now about improving usability and adding support for libraries or GraphQL plug-ins. The documentation is pretty rich and there are a lot of examples available. I think we're in a good shape for a release!
