v4.0.0

This is a new major version of cats-retry, providing new features and a fresh API design.

Major user-facing changes

The major changes in v4 are as follows:

• Scala 3. The library is now published for Scala 3 only.
• Cats Effect. The library is now more strongly coupled to Cats Effect.
• Adaptation. cats-retry now supports adaptation in the face of errors or failures.
• Dynamic retry policies. Retry policies are now more powerful.
• API redesign. The API has been completely rewritten to provide more power and flexibility with fewer combinators.

Migrating from cats-retry v3

cats-retry v4 is not binary-compatible or source-compatible with v3, so you will need to make some changes to your source code.

Please see the migration guide for detailed instructions.

Behind the scenes

• The codebase has been ported to Scala 3 syntax, getting rid of package objects, updating the syntactic sugar to use Scala 3 extension methods, switching to Scala 3 enums, etc
• The tests have been ported from ScalaTest to MUnit, and many test suites have been completely rewritten
• All the dependencies and sbt plugins have been upgraded

Breaking changes

• We now publish artifacts for Scala.js 1.x, not 0.6.x.
• The cats-mtl integration module now depends on cats-mtl 1.x, not 0.7.x. This introduces a bunch of breaking changes within that module, e.g. cats-mtl's ApplicativeHandle is now called Handle.
