[13673.68, 27347.36]])

Convert standard_deduction values to a numpy array and back to a list of value objects:
In [3]: params.from_array(
...: "standard_deduction",
...: params.to_array("standard_deduction", year=[2014, 2015]),
...: year=[2014, 2015]
...: )
Out[3]:

13673.68

{'year': 2014, 'marital_status': 'joint', 'value': 27347.36},
{'year': 2015, 'marital_status': 'single', 'value': 13673.68},
{'year': 2015, 'marital_status': 'joint', 'value': 27347.36}]


- Bug fix for overriding the `ops` values like `array_first` or `label_to_extend` when initializing a `Parameters` instance (104):
python
params = Params(array_first=False, label_to_extend=None)


- Fixes bug in `sort_values` method that occurs when using it in conjunction with `set_state` (106):

python
In [1]: from taxcalc import Policy
...: pol = Policy(array_first=False)
...: pol.select_eq("STD", strict=False, year=[2021])
...: pol.set_year([2018, 2019, 2020, 2021])

In [2]: d = pol.sort_values()

In [3]: pol.STD

for year, rate in params.index_rates.items():
params.index_rates[year] = rate + offset

Select automatically created values:
automatically_added = params.select_eq(
"standard_deduction", strict=True, _auto=True
)

Delete automatically created values and replace using the new rules:
params.delete(
{
"standard_deduction": automatically_added
}
)


- Add a `clobber` argument to the `adjust` method that allows you to toggle whether user-defined values should be overridden while doing an adjustment in extend mode. (102)

- Bug fixes for corner cases in logic for extending parameter values. (103)

- API change in `extend` method to use more concise keyword arguments. The argument `label_to_extend` is now `label` and the `label_to_extend_values` is now `label_values`. (103)

- Ability to specify the state to be used when converting between lists of value objects and arrays (105):
python
Select standard_deduction values in years 2014 and 2015
In [2]: params.to_array("standard_deduction", year=[2014, 2015])
Out[2]:

0.18.1

- Fix bug when using a `when` validator with `defer_validation`. (127)

0.18.0

- Allow comments in JSON files. (124)

python
In [1]: import paramtools

In [2]: s = """// this is my json file
...: // more comments here
...: /*
...: multi line comments?
...: */
...: {
...: "hello": "world",
...: "allows_urls": "http://double-slash-is-ok.com"
...: }"""

In [3]: paramtools.read_json(s)
Out[3]:
OrderedDict([('hello', 'world'),
('allows_urls', 'http://double-slash-is-ok.com')])

0.17.0

- Add `transaction` method for multi-stage updates. (123)
