@brief Future core API, mixing the full power of SimGrid to the power of C++.
-The S4U API is currently under heavy work, but will eventually

-SimGrid will be possible in S4U.
+The S4U API is near from its final state. Everything that you can do in
+SimGrid should be possible in S4U and the missing pieces are seen as
+bugs.
-@warning S4U is not ready for public use yet. You should not go
- that path unless you know what you are doing. If unsure,
- proceed to @ref MSG_API instead.
+@warning S4U is still evolving: v3.18 is a beta release. You
+ are really welcome to test it, but this API may change
+ between releases. This is however the way to go if you want
+ to create a new long-term project. If you want to play safe,
+ proceed to deprecated @ref MSG_API instead.
Unsurprisingly, the S4U interface matches the concepts presented in
@ref starting_components "the introduction". You should read this page
