* Removed `get_trading_dates()`, use `daterange(include_end=True)` instead.
* Renamed `get_trading_date()` to `date()`.
* `date(missing = 'use_last')` is deprecated, use `date(missing = 'use_before')` now.
* `make_calendar()` can now receive an iterator of int, str or`Tradingtate` objects, and the parameter `date_list` is renamed to `dates`.
