That is the commit that removed calls to `withStrictFloats(true)`, which have been the default since 1.9.0, and cannot be changed since 1.19.0. [Cherry-picked bac43a7]
With minimal changes to preserve the status quo. These are forward ports of compiler, library and build changes from the following upstream commits: * scala-js/scala-js@b38201c Drop support for non-strict floats. * scala-js/scala-js@82910a0 Move well-known names to a new object `WellKnownNames`. * scala-js/scala-js@53dc4fe Introduce `NewLambda` to synthesize instances of SAM types. * scala-js/scala-js@9481522 Rewrite old IR with `AnonFunctionN` references to use `NewLambda`. From the `NewLambda` commit, we only adapt the way we compile Scala function lambdas. We do not use `NewLambda` for arbitrary SAM types yet. This is left for a future, independent commit, as it is not required for correctness.

LGTM!
If we need a next RC anyway we can also consider adding JDK 25 support from #23004 Although this one can also be postponed to 3.7.1
