Breaking Changes
mainexport is now ESM, rather than CJS.index.cjs, rather thanindex.cjs.js.experimentalDynamicComponentoption has been renamed todynamicImports, as it is no longer experimental.constto better infer generic types, so may report errors that were previously false negatives.Deprecations
@lwc/engine-serverhas been deprecated. Users should update their code to use the replacement package,@lwc/ssr-runtime.Other Changes
engines.nodeto warn on node 16 or earlier, as LWC uses syntax not supported by those versions of node.Planned, but not included
