OME-Zarr 0.6 allows to compose multi-modal image data across dimensionalities into a joint dataset and ingest it into a supporting viewer of your choice. Combining image data across scales from µm 🧫 to cm 🧠 and beyond will be much easier now! Dataset source: rodare.hzdr.de/record/3131

The main new things in 0.6 are ✨transformations ✨ - adding the "Where" directly to your image data. Some data (e.g., SCAPE microscopy) require a transform to display correctly. View your data correctly, data-duplication free with OME-Zarr 0.6! (UI is WIP, made for @napari.org x napari-ome-zarr)
