# Release Notes

Please note that {{wradlib}} releases follow [semantic versioning](https://semver.org/). API breaks will be announced via deprecation warnings. All {{wradlib}} releases come without any warranty. Release notes might be incomplete. See [commit history](https://github.com/wradlib/wradlib/commits/main) for a complete record of changes.

You can install the latest {{wradlib}} release from PyPI via ``$ python -m pip install wradlib`` or specific version via ``$ pip install wradlib==x.y.z``. The recommended installation process is described in {doc}`installation`.

## Version 2.0.0

For {{wradlib}} 2.0.0 there have been quite some deprecations and additions. Most of the changes have been announced over the latest  {{wradlib}} 1 versions. Nevertheless, to make a clean cut it was neccessary to change and remove code and functionality which was not yet being officially deprecated.

Please follow up at [](./migration.md).

The major new feature is the smooth integration into `xradar`-based reading into `xarray`-based data structures and the convenient use of `xarray`-accessors. The tutorials and examples got a major overhaul to show the capabilities of {{wradlib}} in the light of these new developments.

This version also brings doc-folder back into wradlib repo. The wradlib-docs repo will be archived. wradlib-notebooks repo has been restructured as well, with a single point of access.
