After some discussions and couple of proofs of concept, pandas has decided to move our build system to Meson, from the existing setuptools one (i.e. setup.py build_ext). This is a step other projects in the ecosystem like NumPY already took. The pandas codebase contains a large amount of Cython files that need to be compiled, and using Meson should speed up things and make the build configuration more maintainable.

The main discussion happened in https://github.com/pandas-dev/pandas/pull/47988, thanks core developer Will Ayd for leading the change.
We are happy to announce the release candidate of pandas 1.5.0.

It can be installed from our conda-forge and PyPI packages via mamba, conda and pip, for example:

mamba install -c conda-forge/label/pandas_rc pandas==1.5.0rc0
python -m pip install --upgrade --pre pandas==1.5.0rc0


Users having pandas code in production and maintainers of libraries with pandas as a dependency are strongly recommended to run their test suites with the release candidate, and report any breaking change to our issue tracker before the official 1.5.0 release.

You can find the documentation of pandas 1.5.0 here, and the list of changes in 1.5.0, in the release notes page.

We expect to release the final version of pandas 1.5.0 on September 7th, but the final date will depend on the issues reported to the release candidate.
