v0.17.0-M9

Auto/semi auto derivation: Validator and Schema derivations are now configurable. In order make your code compile as it was before, you need to add an explicit import:

import sttp.tapir.generic.auto._

or separately:

import sttp.tapir.generic.schema._
import sttp.tapir.generic.validator._

You can also use ValidatorDerivation and SchemaDerivation mixins. See https://tapir.softwaremill.com/en/latest/endpoint/customtypes.html#schema-derivation for more details.

There's also a ScalaFix migration available: https://github.com/xela85/TapirGenericAutoMigration.
