This post reads the three things that actually changed in the release notes — v0 symbol mangling promoted to stable, Cargo being able to deny warnings, and linker output no longer hidden by default — and overlays them with the measured experience of building a Kubernetes GPU operator with that very cargo 1.97 a few days earlier. One honest conclusion: what really mattered for writing the operator was not the toolchain version but the ecosystem, kube-rs 0.96. And I lay out, plainly, who should actually upgrade now.
