libpd has reached a 0.1 release, enabling developers to use Pd as a sound engine in their applications. Out of the gate, we have extensive code samples for Android 1.5 and later, plus the basic tools to work on iOS (recent armv7 recommended for now, with other devices soon). In the near future, embedding Pd patches inside tools like Processing/Java, OpenFrameworks/C++, and Python should be just as easy. The library is based on Pd vanilla, so this is not a fork of Pd; you can use patches in it just as you would in any other version.
