ParamTools 0.17.0

• Add transaction method for multi-stage updates. (#123)
  
• Use Github Actions for CI. (#123)

ParamTools 0.16.0

• New API for querying parameter values:
  

• Improvements for querying custom/nested values:
  

ParamTools 0.15.1

• Fix several ordering bugs affecting the order of schema vs parameter names in the output of Parameters.dump and the order of keys in value objects. (#115)
• Expose argument to use the labels set in the state of the Parameters instance when selecting which values to include when calling Parameters.dump. (#115)
• Use most up-to-date operator values when dumping a Parameter values to JSON. (#118)

ParamTools 0.15.0

• Use fsspec to support a rich variety of inputs sources from local JSON files to files stored on GitHub, S3, or Google Cloud Storage. (#111, #113)

ParamTools 0.14.2

• Fix deserialization bug. (#109)

ParamTools 0.14.1

• Perfomance improvements to extend functionality. (#107)
• Bug fix for sort_values that caused an error when calling dump on a Parameters instance that does not specify any labels. (#108)

ParamTools 0.14.0

• Add the _auto attribute to parameter values that were extended automatically. This make it possible to update the rules for how parameters should be extended, delete the extended values, and update with the new rules (#102):

# Update extension rules:
offset = 0.0025
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):

# Select standard_deduction values in years 2014 and 2015
In [2]: params.to_array("standard_deduction", year=[2014, 2015])

• Bug fix for overriding the ops values like array_first or label_to_extend when initializing a Parameters instance (#104):

params = Params(array_first=False, label_to_extend=None)
