I'm running mosh 1.2.4 on my Ubuntu server, and it's always annoyed me that it doesn't print the message of the day (MOTD) on startup. ssh prints helpful information when you log in, like if you need to reboot or update packages, that I miss when logging in via mosh.
So you can imagine my surprise when I found out that this issue was fixed in version 1.2 of mosh, 4 versions ago!
