The last Where is Io release was a few weeks ago. That's because I've been working through a new chunk of math that I'll need for a few new features. One of the things I needed was rise and set times for Jupiter and the Sun, which quickly turned into all the planets (because it's basically no additional work to fill it in for everything else). The application is evolving in it's own direction into a more general solar system almanac, which makes me wonder if a new name is going to be in order on the next release (probably called 2.0 because of so many changes). Name suggestions are welcomed.
