Files still referring to the old version number

The following files still refer to the old version number (2.13.8).
You might want to review and update them manually.

core/src/main/scala/cats/data/Chain.scala
tests/shared/src/test/scala-2.12/cats/tests/compat/SeqOps.scala

Adjust future updates

Add this to your .scala-steward.conf file to ignore future updates of this dependency:

updates.ignore = [ { groupId = "org.scala-lang" } ]

Or, add this to slow down future updates of this dependency:

dependencyOverrides = [{
  pullRequests = { frequency = "@monthly" },
  dependency = { groupId = "org.scala-lang" }
}]
