v0.8.11

Some major updates:

1. The API was simplified:

• Instead of the ugly context.obj["configurations"], there is context.configs. And so on.
• Tuning comes for free, no need to worry anymore about context.obj["extra_parameters"]
• For convenience there is now context.params
• The docs were updated and changes are backward compatible.

2. Users can now save artifacts and outputs at different locations, and it's all a bit simpler to specify. Go to the docs to read more.
