# Zarr Python
## When to use
Use for chunked scientific arrays, hierarchical stores, codecs, sharding, partial reads,
cloud object storage, and NumPy/Dask/Xarray interoperability. This community guide targets
**Zarr-Python 3.4.0**, released **2026-09-15**, with Python 3.12+. The package version and
on-disk format are separate: this release reads/writes formats 2 and 3; new arrays default
to format 3. Keep downstream packages that require `zarr<3` in their own environments.
## Install
```bash
uv pip install "zarr==3.4.0" "numpy==2.5.3"
