 # Scala 3 support
 
-Pekko has experimental support for Scala 3.
-
-## Using 2.13 artifacts in Scala 3
-
-You can use [CrossVersion.for3Use2_13](https://scala-lang.org/blog/2021/04/08/scala-3-in-sbt.html#using-scala-213-libraries-in-scala-3)
-to use the regular 2.13 Pekko artifacts in a Scala 3 project. This has been
-shown to be successful for Streams, HTTP and gRPC-heavy applications.
-
-## Scala 3 artifacts
-
-We are publishing experimental Scala 3 artifacts that can be used 'directly' (without `CrossVersion`) with Scala 3.
-
-We do not promise @ref:[binary compatibility](../common/binary-compatibility-rules.md) for these artifacts yet.
+Pekko has support for Scala 3. Pekko is built with Scala 3.3 LTS version and we are confident that no binary incompatible changes should be necessary due to Scala 3 changes. See the @ref:[binary compatibility documentation](../common/binary-compatibility-rules.md).
