2.14.0

Because the behavior of Using has changed, Using users should adopt this release in tandem with upgrading to Scala 2.13.17.

If your crossbuild also includes Scala 3, then you may wish to also wait for a Scala 3 release that has itself taken the upgrade to the 2.13.17 standard library, so your entire CI matrix will get the same behavior.
