🚀 Major Release

New Function Names and API Structure:
- Introduced source-specific deflator functions (e.g., imf_gdp_deflate, wb_gdp_deflate, oecd_dac_deflate).
- Added source-specific exchange functions for currency conversion (e.g., imf_exchange, oecd_dac_exchange).
Deprecated deflate function; users are encouraged to transition to new deflator functions.
Improved Setup and Data Requirements:
- Streamlined DataFrame requirements: id_column, year_column, and value_column now required explicitly.
- Added use_source_codes parameter to allow for DAC, IMF, and other source-specific country codes.
And much more. Please see the release documentation or the readme for more details.

1.3.0 (2023-02-19)

This release includes a major refactoring/rewriting of the underlying logic, tools to get and manage the data, and tests.

No breaking changes were introduced, but the API for the deflate and exchange() functions has changed. The new API has more consistent naming and provides additional options. The old API is still available, but will be deprecated in a future release. Using the old parameters will raise a warning.

New features:

Added new exchange rates for the IMF. As a side effect, deflators can now be calculated for future years for which the IMF has GDP projections.
A data folder can now be specified by calling pydeflate.set_pydeflate_path(). This allows users to specify where the data should be stored.
Users can now specify (and therefore combine) the source of deflators and exchange rates.

1.2.10 (2023-01-12)

Updated requirements.

1.2.9 (2022-12-21)

Greatly improved how DAC deflators are handled for the "DAC Total" grouping. It now tracks the data as used in the database even if the published "deflator" figures differ.

Update requirements.

- Reduced the precision level of deflators and exchange rates on DAC data. This update aligns with the precision level in DAC data, as published by the OECD.

1.2.2 (2022-11-03)

Fix issues with pd.NA when too many values are replaced. It now uses np.nan.

This version is a complete rewrite of the package. Please refer to the documentation for information on how pydeflate works
The basic functionality of pydeflate can now be considered to be settled. Further releases to pydeflate will extend what is possible, without altering the basic way in which pydeflate works.

0.1.4 (2021-04-21)
