--- title: Release 1.13 date: 2021-11-14 11:00 category: news authors: wradlib tags: releases, github, python3 --- # Release 1.13 We have now released version 1.13 of wradlib. After missing `requirements_optional.txt` in the source distribution which has been uploaded to ``PyPI`` as `1.12.0`, we had to remove this version from ``PyPI`` again. The problem was that the installation from the source distribution was not possible without this file. Anyway, this was fixed and {{wradlib}} `1.13.0` was released shortly after. This version contains two enhancements and a whole bunch of bugfixes. Some dependencies have been made optional as well. The hard dependencies of {{wradlib}} are codewise: - deprecation - matplotlib - numpy - scipy - xarray>=0.17.0 This has no affect on current versions `< 2.0` doing normal install or by installing via conda-forge. But you can already test this by installing {{wradlib}} using pip: :::bash $ python -m pip install wradlib==1.13.0 --no-deps Or from inside the latest cloned/extracted {{wradlib}} github-main: :::bash $ python -m pip install . --no-deps Now, these are the most important changes: **New features** - add [IRIS/sigmet backend](https://docs.wradlib.org/en/1.13.0/notebooks/fileio/wradlib_iris_backend.html) for reading radar data into xarray Datasets - add [Rainbow5 backend](https://docs.wradlib.org/en/1.13.0/notebooks/fileio/wradlib_rainbow_backend.html) for reading radar data into xarray Datasets **Maintenance** - optionalize dependencies (dask, gdal, h5netcdf, h5py, netCDF4, requests, xmltodict) - use pytest-doctestplus to handle optional dependencies in doctests - fix docstrings **Bugfixes** - use reasonable default values in io.xarray.to_odim (gain, offset, nodata, undetect, fillvalue) - add cf attributes when reading GAMIC files - fix regression in legacy GAMIC reader - catch dt.accessor TypeError - fix thread-lock issue, if dask is not installed - use int instead np.int in radolan header parser - fix several tests We like to thank all our contributors and all community members who ask questions and provide feedback on the various channels.
