What shifted

How the specification changed

Focused on reducing verbosity while keeping the core language model familiar to existing Java developers.

It made everyday Java coding lighter and safer, especially for resource handling and type inference in common cases.

Reading note

Why this edition matters

This is a pragmatic milestone rather than a complete reinvention of the language.

A good edition to review when studying Java's transition from classic verbosity to incremental language polish.
