The SunPy Project is pleased to announce the first release candidate for version 5.1 of the sunpy core library. If you develop a package that depends on sunpy we would strongly encourage you to test it with sunpy v5.1.0rc1, and report any issues you have on our issue tracker (Issues · sunpy/sunpy · GitHub) so we can fix them before the final release.
To install the release candidate use either:
pip install --pre sunpy==5.1.0rc1
conda install -c conda-forge/label/sunpy_rc -c conda-forge sunpy
