+### `v2.0` - 23.01.2026
+
+Since updating the `datasets` package to `v4.0`, HuggingFace does not support `trust_remote_code` anymore. As a consequence, we've had to rethink the whole structure of this repository. The Parquet files were always stored at `datasets/prs-eth/AGBD_raw`. For versions < `2.0`, the `AGBD.py` file in the present repository was loading the Parquet files and applying various processing steps, based on the arguments the user would pass the `load_dataset()` function. From version `2.0`, we stream the data directly from `datasets/prs-eth/AGBD_raw`, and provide the pre-processing functions in a `helper.py` file. We provide examples in the `README.MD` for how to use those functions.

 ## `v1.1.2` - 26.02.2025
 
 In `AGBD.py`, line 179, the indexing was changed from `[:, :, i]` to `[i, :, :]` (see the corresponding [commit](https://huggingface.co/datasets/prs-eth/AGBD/commit/8ac67eceb8edcb8e198016f4e4b79bb527bae715)). More explicitely, the normalization of the Sentinel-2 and ALOS bands was wrong, because the dimensions were mistakenly taken for (patch_dim_1, patch_dim_2, bands) instead of (bands, patch_dim_1, patch_dim_2).
