LibraUSD, LibraEUR, LibraGBP, LibraSGD

Hi guys, I’ve integrated Libra into my platform and I’m currently looking into integrating LibraUSD, LibraEUR, LibraSGD, LibraGBP. Does anyone know if LibraUSD, LibraEUR, LibraSGD, LibraGBP are out or when will they be out?

If they are out, can you direct me to the integration resrouces please?
