What's this all about?

jDFT 2.5 released!! (2007-08-02)
Finally, by request of several users, a feature that makes pink noise read flat has been implemented.

New zoom feature (v 2.3): The new feature is an intuitive way of zooming in to the frequency region you're interested in. Just hold the left mouse button down while moving the mouse over the frequency region you want to take a closer look at. Release the left mouse button for the zoom to take effect.
