 # Changelog
+## 0.9.1 (2025-10-21)
+- Added missing CFs for Nitrogen emissions to groundwater
+
+## 0.9.1 (2025-10-06)
+- Adapt the PB-LCIA method for ecoinvent 3.9.1
+- Add the PB **Atmospheric Aerosol Loading**. CFs from [Ryberg et al.](https://doi.org/10.1016/j.ecolind.2017.12.065)
+
 ## 0.9.0 (2022-07-25)
 - Files containing CFs information are now stored in .yaml format (instead of .xlsx)
   - `add_aesa_pbs()` still reads .xlsx files, which are generated in the background on execution with the help of the functionality added by the `DataConverter` class
