+* Add streaming write support to enable writing larger-than-ram dask-backed arrays and datasets ([#108](https://github.com/open-meteo/python-omfiles/issues/108)) ([9077abb](https://github.com/open-meteo/python-omfiles/commit/9077abb128bd4af0a4695e175db43b26b402d3b5))
+* implement scale_factor and add_offset getters for both readers ([#127](https://github.com/open-meteo/python-omfiles/issues/127)) ([a3628dd](https://github.com/open-meteo/python-omfiles/commit/a3628ddd27cd18c14ba763580cfe8533bde36fbf))
+
+
+### Bug Fixes
+
+* add tests for non contiguous behavior ([#123](https://github.com/open-meteo/python-omfiles/issues/123)) ([10ac68b](https://github.com/open-meteo/python-omfiles/commit/10ac68bea33f9630772c20a45e6abbef7b3f2e85))
