This version includes changes for the proposals for:

  #CompileTimeDependences (`requires static`)
  #ReflectiveAccessToNonExportedTypes (`exports dynamic`)
  #ModuleAnnotations
  #ClassFileAccPublic

It also defines class-file attributes for concealed packages, version
strings, main classes, and target platform information.
