The releasse includes support for interop export names, a bug requiring investigation, and a bug related to different libraries shipped with TypeScript. The release also addresses issues related to parameters not working in JS files unless a @param has been explicitly defined. Additionally, the release addresses issues related to expanding quick info/hover verbosity and type display.
