If enabled, generated WebAssembly code will target "WebAssembly 2023", a Unity-coined name for a selection of newer WebAssembly language features. These features include: sign-extension opcodes, non-trapping fp-to-int instructions, bulk memory, JS BigInt integration, WebAssembly.Table, native WebAssembly exceptions and SIMD. Requires Chrome ≥ 91 (May 2021), Firefox ≥ 89 (June 2021) or Safari ≥ 16.4 (March 2023). If disabled, targets the original WebAssembly "MVP" feature set.
