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)

One of my favourite data discoveries this year: Google's mind-blowing ARCO-ERA5 dataset: hourly data for ~300 climate variables, available globally from 1940! 🤯
Loadable with a single line of Python code from a single cloud-friendly Zarr file! Below: a month of wind waves + swell: 🌊
