I'm excited to announce that the beta version of Liquid Threads 3 is now available. We've come a long way from a once-dead project by developing the extension in secret. It's full of new features: including the incredibly simple Morse Code input system. LQT3 will be deployed to all Wikimedia wikis whether you like it or not.
