I just stumbled over the upgrading instructions to 2.x for MySQL users (https://www.roundup-tracker.org/docs/upgrading.html#python-2-mysql-users-must-read), to which i would like to propose an improvement.

I would not advise to set the MySQL database encoding to utf, but to utf8mb4 instead. Utf8 in MySQL is limited to use only up to 3 bytes per character, and thus cannot store all characters that you would expect maybe. Especially Emojis will not work, which is a pity, as these have a high probability of arriving through the Email interface :-)
