----------------------
This release marks VirtualiZarr as mostly feature-complete, in the sense of achieving feature parity with kerchunk's logic for combining datasets, providing an easier way to manipulate kerchunk references in memory and generate kerchunk reference files on disk.
Future VirtualiZarr development will focus on generalizing and upstreaming useful concepts into the Zarr specification, the Zarr-Python library, Xarray, and possibly some new packages. See the roadmap in the documentation for details.
