           @b{4.0.0 is a major breaking change in uPickle, including in the serialization
           format for many common data types (@hl.scala{Option}s, @hl.scala{sealed trait}s,
           etc.), as well as breaking binary compatibility. Please be

-          uPickle 4.0.0-RC1 is a release candidate. It breaks backwards compatibility with
-          uPickle 3.x (binary and serialization), but makes no promises for compatibility
-          with uPickle 4.0.0 final. Hopefully nothing will need to change between 4.0.0-RC1
-          and 4.0.0 final, but it cannot be guaranteed.
