+## [0.3.0] - 2025-11-04
+
+### Added
+- `eopf_geozarr.s2_optimization` module with streaming multiscale generation, CLI commands, and validation for Sentinel-2 L2A.
+- End-to-end sharding support spanning CLI flags, conversion helpers, Dask execution, and encoding metadata.
+- Geo Projection attribute extension documentation plus schema to lock GeoZarr metadata expectations.
+
+### Changed
+- Tightened spatial chunk and shard defaults to cut write overhead on large scenes.
+- Relocated the entire test suite under `src/eopf_geozarr/tests` and broadened type coverage for tooling.
+- Smoothed multiscale metadata handling during streaming writes to keep Sentinel datasets consistent.
+
+### Fixed
+- Preserved coordinate dtypes in overview levels and stopped auxiliary coordinate write failures.
+- Prevented streaming metadata consolidation from overwriting existing groups between runs.
+
+## [0.2.0] - 2025-09-22
+
+### Added
+- Sentinel-1 GRD integration tests and CLI wiring to enforce GeoZarr compliance end to end.
+- Reprojection utilities with GCP selection and grid-mapping output for Sentinel-1 converts.
+
+### Changed
+- Extended `create_geozarr_dataset` to understand VV/VH polarization groups and build GCP-backed overviews.
+- Tuned chunk-size calculation and encoding helpers so shard dimensions and auxiliaries align.
+
+### Fixed
+- Stopped auxiliary coordinate writes from failing in overviews when chunked.
+- Silenced noisy CLI warnings and aligned launch configs with the packaged tests.
+
