If you are going to write your own allocators, I think it doesn't matter too much which Zig version you are on. Most drastic changes since 0.15 are done to the standard lib and the language itself stayed pretty much the same. That said, they did clear a lot of bugs which I would never run into, because I make relatively simple programs. But with writing things like allocators, you might reach those edgecases a bit sooner.
