One of the most versatile codes around, PLUTO, has reached version 3.0.

It considerably improves over PLUTO 2 in several aspects such as AMR, improved I/O and several new algorithms. Download the source code plus examples and documentation from http://plutocode.to.astro.it/ and check the file CHANGES in the PLUTO/ root directory to learn about the improvements in detail. For a rough overview (in case you don't know PLUTO yet) look at the codes section in the menu at the left side of this page.
