I am announcing that I have released a more stable version of LOS 15.1. Is Beta NOW

Compared to the last version of Telegram released here, this one uses all four CPU cores; it has switched back to the "interactive" governor instead of "ondemand," and I’ve improved the log spam. Just a reminder: the ROM isn't finished yet.
