Fans of Hydrogen drum machine software may be interested to know that version 0.9.5 was just released. There doesn't seem to be any binaries just yet, only source code, but I'm sure the binaries will be available soon.
One interesting new feature is a built-in sample editor. Here's a video about it. Unfortunately, the commentary is in German so most of us won't learn much from it. But at least you can see what the sample editor looks like.
