It looks like the intent is to allow distributing modified versions as long as you follow all of the conditions of section 3 *or* all of the conditions of section 4. The license might not actually say that, though. I wonder why an ugly mandatory-changelog clause was added. One reason I like the BSD license is that it doesn't put a lot of requirements on code reuse--no mandatory source release and no mandatory changelogs. (Besides, good programming practices shouldn't be mandated by licenses.) This license really has little to do with the BSD license, though. I think claiming association with it is bordering on deceptive ... -- Glenn Maynard
