 ## Building on modern systems
 
-ns-2.29 (2005) doesn't compile with modern compilers. The included Docker-based build uses **Ubuntu 18.04 + GCC 7** (the last GCC that compiles ns-2 out of the box). Verified on macOS Apple Silicon and Linux in 2026.

 ### The problem
 
-ns-2.29 was written in 2005 using pre-C++11 idioms that modern compilers reject:
+ns-2 (and DiffServ4NS) use pre-C++11 idioms that modern compilers reject:
 
 - Implicit `int` return types and K&R-style declarations
