To me it is not much different from Lua, which despite being on 5.x for decades, makes breaking changes on minor releases (because it predates SemVer).
I also don’t see it being much different from any other language or language runtime that has a major release every year.
It’s fine to update at your own pace.
I did, and I immediately found this in the latest release: https://ziglang.org/download/0.16.0/release-notes.html#IO-as...
That seems like it would require changing a lot of code. Calling it "production ready" is dishonest at best
If by production-ready you mean you can forever avoid changing code you wrote 8 months ago, sure, pick something else.
To me production-ready means it can be trusted to power production workloads, has all tooling I need, and has a consistent long-term vision. Zig ticks all the boxes.
That sounds like it's not ready for production to me.
