I'm glad I can make the announcement that Autoweight 0.055 is available now.

There are a couple of new features like
* a weighting-falloff curve
* a mirror function
* an automatic region setup function according to your bones (still needs some work for complex characters for sure)
* speed up region selection
* multiple region selections
* additional bugfixes ;)
If you liked Autoweight 0.030 you might like the new version even more cause it makes the skin-weighting life a easier.
