This manual contains the 0.7.1 API standard. 0.7.x versions are development versions, which will be used until a stable, usable and complete version is reached. By that time, version number will be upgraded to 0.9. The 0.9.x versions will be for debugging and testing, because minor corrections are to be expected. Once it's good enough to be widely, publicly used, it will be 1.0.
So, in other words, while it's not 1.0, you can't blame us that it sucks and doesn't work. After that, it's OK. :-)
