+## 21.5.1
+
+### Major Changes
+
+- From this version, Airframe DI for Scala 3.0.0 is available. For Scala 3, Airframe DI only supports constructor injection. We will deprecate in-trait injection support in upcoming versions. For more details, see also [airframe-di migraiton plan](https://github.com/wvlet/airframe/issues/1649).
+- AirSpec deprecates function-style test specs and only uses `test("...") { ... }` syntax. This version shows warning messages if you are still using public functions as test cases. This test support will be removed from the next version of AirSpec. This is [a necessary step toward supporting Scala 3](https://github.com/wvlet/airframe/issues/1659).
