- 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 striclty 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.

Technical changes

- Increase spiral and cycle tests robustness.
- The current test is ambiguous, as it hides a failure at the first spiral
occurrence (from 2017 to 2016).

Technical changes

- Changes the Pypi's deployment authentication way to use token API following Pypi's 2FA enforcement starting 2024/01/01.

Technical changes

- Check that entities are fully specified when expanding over axes.

New features

- Add `entities.find_role()` to find roles by key and `max`.

Technical changes

- Document `projectors.get_projector_from_shortcut()`.

> As `TracingParameterNodeAtInstant` is a wrapper for `ParameterNodeAtInstant`
> which allows iteration and the use of `contains`, it was not possible
> to use those on a `TracingParameterNodeAtInstant`

New features

- Allows iterations on `TracingParameterNodeAtInstant`
- Allows keyword `contains` on `TracingParameterNodeAtInstant`
