 Language changes
 ----------------
 
+* Newly created Task objects (`@spawn`, `@async`, etc.) now adopt the world-age for methods from their parent
+  Task upon creation, instead of using the global latest world at start. This is done to enable inference to
+  eventually optimize these calls. Places that wish for the old behavior may use `Base.invokelatest`. ([#41449])
 
 Compiler/Runtime improvements
