Python 3.14 Preview: Lazy Annotations

Recent Python releases have introduced several small improvements to the type hinting system, but Python 3.14 brings a single major change: lazy annotations. This change delays annotation evaluation until explicitly requested, improving performance and resolving issues with forward references. Library maintainers might need to adapt, but for regular Python users, this change promises a simpler and faster development experience.
