GC and Exceptions in Wasmtime
Wasmtime 47 now enables garbage collection and exception handling by default, removing significant barriers for high-level programming languages to compile efficiently to WebAssembly by eliminating the need for embedded garbage collectors and custom exception handling code. This advancement expands WebAssembly's applicability across enterprise environments where Wasmtime is deployed, enabling organizations to run a broader range of applications with improved performance, reduced binary sizes, and maintained security guarantees through sandboxed memory management. IT leaders should recognize this as a maturation milestone that increases WebAssembly's viability for production workloads, but should plan for performance optimization iterations in coming releases.
