For more information on F-Chat Rising, see the github for it.
This builds directly from source and depends on a system-wide install of electron instead of using a bundled version.
This version also includes a convenience patch for saving any unsent messages in channels to a file under the log directory as deadletter.log. Though intentionally closing F-Chat's last tab will not allow it to save, on unstable connections it is immensely helpful to avoid losing paragraphs of work while composing in a channel.
