Opening Keynote
summary
Roadmap announces concrete changes: a conventional pods-style file layout with codemods to migrate apps, making jQuery optional (≈30KB) and reducing default size by about one fifth, testing helpers move to promise-returning async functions, modules enable tree-shaking, and class features use decorators and tracked fields to eliminate dot get. Performance work shows a LinkedIn feed prototype with glimmer vs preact hitting first meaningful paint <3s and server rendering shaving ~1.5s; a Rust/WebAssembly VM branch runs the full test suite but iOS has a temporary compatibility issue.
