The key feature of this update is the introduction of emoji support. See the Emoji Cheat Sheet for a list of supported Emoji.
For example, sup add ":laughing: Told a funny joke" will output: 😆 Told a funny joke in the terminal.
This feature also introduces support for listing tasks for an arbitrary date. For example, sup list --date 2019-03-31 will list all tasks for that date.
