Breaking Changes

@typespec/compiler

  • #4539 Config parameters and emitters options cannot contains .. This conflict with newly added support for nested options.
  • #4500 API: Update default of decoratorArgMarshalling from legacy to new

To revert to the old behavior export the following. Highly discouraged, this will be removed in a few versions.

export const $flags = definePackageFlags({
  decoratorArgMarshalling: "legacy",
});
  • TypeSpec compiler expect the entrypoint to be an absolute path. This used to work with some alternative CompilerHost that handled relative path but this is no longer supported due to the new exports field support.
