- Request parameter at a given date with the `parameters.benefits('2015-07-01')` notation.
- Be more flexible about parameters definitions
The two following expressions are for instance strictly equivalent:
Parameter("taxes.rate", {"2015-01-01": 2000})
Parameter("taxes.rate", {"values": {"2015-01-01":{"value": 2000}}})
- Make sure `parameters.benefits('2015-07-01')` and `parameters.benefits('2015-07')` return the same value.
- Raise an error when calling `parameters.benefits('invalid_key')`.
- Improve errors when `parameter.update` is used with wrong arguments
Deprecations
- Deprecate `ValuesHistory` class. Use `Parameter` instead.
- Deprecate `parameter.values_history`. Just use `parameter` instead.
