What shifted

How the specification changed

Shows that a healthy language spec is not only about marquee features but also about continuous refinement and precision.

It helped keep the language coherent as multiple preview and finalized features accumulated.

Reading note

Why this edition matters

Smaller-looking editions still matter because they shape the exact behavior developers rely on.

Useful as a reminder that specification quality depends on incremental maintenance too.
