 Starting from version 1.4.0, we'll pick one species from [_the endemic species of Taiwan_](https://en.wikipedia.org/wiki/List_of_endemic_species_of_Taiwan) as version name. Is there anyone still remember we've once used type of coffee as our version name? It's time to revive that good convention, but this time we don't need coffee to stay up all night. 💤
