Midnight has been updated to version 1.1.0.

This version of Midnight has been completely rewritten, from the ground up, to support Mac OS X Leopard (10.5).

New in this version:

1. You can name individual instances of Midnight.
2. The addition of an option to turn airport off before sleeping (it is turned back on a little while after waking).

To retain your current preferences when installing a new version of Midnight, reload the old version by clicking on it (the edge, not the image of Mac) and pressing Command+R, the widget should swirl as it reloads and hopefully all your preferences should be retained.
