 ### Changed
 
 -   We changed the order of imports in generated widget prop types to match that of the eslint sort-imports rule.
--   We replaced `ts-jest` with `@swc/jest` as the Jest transform (3–5× faster for TSX-heavy test suites) and switched the test runner from `jest-jasmine2` to `jest-circus`. The default test timeout is now 10 000 ms (previously 5 000 ms).
