Known issues

gotchaarnio's load function returns a pandas DataFrame by default, but certain options may return an arnio Dataset object. Always check the type.

fix

Use from arnio import load and inspect type(df).

affects: >=1.0.0

breakingIn version 1.15.0, the 'parallel' parameter was removed from load(). Code using it will break.

fix

Remove 'parallel' argument; parallelization is now automatic.

affects: >=1.15.0
