Breaking Changes

• To continue using @rbxts/roact + JSX
  • roblox-ts 3.0.0+ will require @rbxts/roact 3.0.1+
  • Class components must be tagged with @Roact.ClassComponent
  • Top-level JSX expressions no longer support Key. To preserve previous behavior, you should wrap it in a fragment: tsx <><screengui Key="ScreenGui" />
  • In tsconfig.json you should set the following json "jsx": "react", "jsxFactory": "Roact.jsx", "jsxFragmentFactory": "Roact.Fragment",
• Upgraded bundled roblox-lua-promise from 3.2.1 to 4.0.0. See possible breaking changes here.
• The TypeScript update includes a few edge-case breaking changes: 5.4 and 5.5
• roblox-ts will emit compiled files as .luau by default. You can keep the old behaviour by running with --luau=false.
• Parameter decorators will now be called with the name of the method, instead of the name of the parameter. This matches TypeScript behaviour.
