Wasm 3.0 is officially released, introducing major enhancements like 64-bit memory addressing, native garbage collection, multiple memories per module, and exception handling. These updates significantly expand Wasm's capabilities beyond its original web-focused constraints, enabling more complex and larger applications.

Why it matters: Wasm 3.0 enables larger, more performant applications with advanced features like GC and exceptions, improving support for high-level languages.

The big picture: This release marks a major evolution of Wasm from a web-only runtime to a versatile platform for diverse software ecosystems.

The stakes: While powerful, new features like garbage collection and exception handling may complicate implementation and performance tuning.

Commenters say: Enthusiasts applaud the long-awaited features and 64-bit support but caution that GC is low-level and not a universal solution; some debate exception handling choices.
