September 2025: Delivered IGV Browser URL support for Google Cloud Storage (GCS) and DRS-based tracks in terra-ui. Implemented URL translation utilities and a processUrl function to translate signed GCS URLs while preserving non-DRS GCS URLs. Updated tests to verify URL transformations and ensure reliable remote data loading. Restored IGV compatibility for both DRS URIs and non-DRS URIs, significantly improving track loading reliability from cloud storage.
