C is not frozen.

C11 added generics, multi-threading, unicode support, static assertions. It broken compatibility with earlier versions by removing `gets` function.

C23 added `nullptr`, very fundamental change. typeof operator. auto keyword for type inference. Lots of breaking changes by introducing new keywords. Another breaking change is empty brackets `()` now mean as function taking no arguments.

So lots of new features and breaking changes with every new iteration. Thankfully, compilers support sane standards, so you can just use `-ansi` and live happy life, I guess...
