Beyond ICU4X 2.0
summary
ICU4X 2.0 ships this week as a Rust-native i18n stack that is faster than ICU4C, cuts binary size dramatically (about half the binary size since 1.5), and avoids heap allocations for most formatting paths. It already runs in Firefox, Pixel Watch ambient mode, Android and WASM, and targets devices from microcontrollers to data centers. Key pieces are zero-copy deserialization (zerovec, yoke), databake (compile-time data as Rust), and Diplomat for multi-language bindings.
