 @brief Future core API, mixing the full power of SimGrid to the power of C++. 
 

-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 <b>S4U is still evolving: v3.18 is a beta release</b>. 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
-first, to not get lost in the amount of classes provided here. Or you
-could jump to the @ref s4u_examples directly if you prefer.
+@b TLDR: The best documentation is the @ref s4u_examples
+
+Currently (v3.21), S4U is definitely the way to go for long-term
+projects. It is feature complete, but may still evolve slightly in the
+future releases. It can already be used to do everything that can be
+done in SimGrid, but you may have to adapt your code in future
+releases. When this happens, compiling your code will produce
+deprecation warnings for 4 releases (one year) before the removal of
+the old symbols. 
+If you want an API that will never ever evolve in the future, proceed
+to the deprecated @ref MSG_API instead.

+The S4U interface matches the concepts presented in @ref
+starting_components "the introduction". You should read this page
