uv 0.12.0 changes default project structure to src-layout with new build backend
“I've so far avoided using src layout in my own projects just out of inertia. I think it's time I switched.”
uv 0.12.0 changes the default project scaffold from a flat layout to a src/ layout and introduces uv_build as the default build backend. This is a developer tooling update with no direct AI industry signal. Relevant only as Python ecosystem infrastructure that AI developers use.
