# Version Log **Version 1.0.37 - 22nd April 2026** * Introduced `functional_unit` on get\_products API to convert the data into a pre-specifed unit. **Version 1.0.36 - 11th April 2026** * Renamed the `"material_types"` response key to `"material_type"` (singular) in the `get_product_filters` endpoint, consistent with the `material_type` parameter used by `get_products`. The request parameter `?filters=material_types` continues to work as a backward-compatible alias. * Updated the `"filter_type"` values for certification filters in `get_product_filters` from `"certification_types"` / `"certification_types_family"` to `"certificate_type"` / `"certificate_type_family"`, aligning with the query parameters accepted by `get_products`. The old request parameters `?certification_types=` and `?certification_types_family=` continue to work as backward-compatible aliases. **Version 1.0.35 - 30th March 2026** * Updated the Boverkets generic materials database to V02.07.000 **Version 1.0.34 - 27th March 2026** * Added `__min` / `__max` range filtering support to `get_products` and `get_generic_materials` endpoints, enabling numerical field filtering across LCA, physical, technical, circularity, HVAC, carbon, environmental, and grey energy fields **Version 1.0.33 - 18th March 2026** * Expanded the generic materials database by including an MEP Machinery database calculated by the 2050 Materials Research team. * Expanded the fields of the `get_products` API to include `standardised_name` , a better way to search for products by technical parameters. * Expanded the data points under the generic data source `2050 Materials Research (Structural Materials)` to include Structural Steel with (20%, 40%, 60%, 80% Recycled Content) **Version 1.0.32 - 5th December 2025** * Expanded the generic materials database by including the newest [Boverkets](https://www.boverket.se/sv/PBL-kunskapsbanken/regler-om-byggande/boverkets-byggregler/) (Swedish Generic Database). **Version 1.0.31 - 1st December 2025** * Included a new API filter on /get\_products to exclude products without a specific field (e.g. `exclude_nulls=manufacturing` **Version 1.0.30 - 18th November 2025** * Expanded the generic materials database by including the newest [ICE Database (V4.1)](/data-documentation/data-sources.md) by Circular Ecology **Version 1.0.30 - 16th November 2025** * Updated the `unique_product_uuid_v2` filter behaviour on `get_products` to allow multiple uuids, comma-separated. **Version 1.0.29 - 12th November 2025** * Updated the `certificate_url` field behavior for product APIs and CSVs. For security reasons, links will now trigger an automatic PDF download instead of displaying the file in the browser. **Version 1.0.28 - 4th September 2025** * Added functionality to sort get\_products results by proximity to a lat/long or a location (see more [here](/readme/using-the-2050-materials-api/available-endpoints/product-data-full.md#filtering-the-data)) * Included "city" under `get_product_filters` and enabled filtering by the same field on `get_products` * Included a mapping dictionary to indicate cities under a country under `get_product_filters` `Example: 'country_city_map': {'Algeria': [{'id': 1541, 'value': 'Bethioua'},...` **Version 1.0.27 - 28th August 2025** * Expanded the Generic Data by including the [New Zealand Environment Ministry GHG Database (2025)](https://environment.govt.nz/publications/measuring-emissions-guide-2025/) **Version 1.0.26 - 14th August 2025** * Added our new sdk ([sdk.2050-materials.com](https://sdk.2050-materials.com)) to the documentation **Version 1.0.25 - 11th August 2025** * Updated the Data Sources table under [Generic Material Data](/readme/using-the-2050-materials-api/available-endpoints/generic-material-data.md) to reflect the upload of the 2022 UK GHG Factors database. **Version 1.0.24 - 3rd August 2025** * Updated the output fields under the [Generic Material Data](/readme/using-the-2050-materials-api/available-endpoints/generic-material-data.md) endpoint to reflect new fields: * `linear_density`, `mass_per_piece`, `cross_sectional_area`, `mass_per_declared_unit` **Version 1.0.23 - 8th July 2025** * Uploaded the new UK GHG Conversion Factors 2025 ([source](https://www.gov.uk/government/publications/greenhouse-gas-reporting-conversion-factors-2025)) under the [Generic Material Data](/readme/using-the-2050-materials-api/available-endpoints/generic-material-data.md) endpoint. **Version 1.0.22 - 26th June 2025** * Updated data sources for generic materials endpoint to reflect the new MEP database generated by the 2050 Materials research team. * Improvements to the speed of `get_product_filters` endpoint * Introduced a new field under `get_products` called `certificates` with information on all available certificates on products (e.g. FSC, Datasheets, etc.).
