Control: tags -1 pending Hi,
I've applied the patch in Git and also tried to upgrade to latest upstream since there is a chance that other Python3.12 issues might be fixed. Unfortunately the upgrade is all but straightforward and I gave up finally over the changes in the sphinx documention where finally some files are missing. I've created a branch 2023.12.18 which fails with Sphinx error: root file /build/pymatgen-2023.12.18+dfsg1/docs/apidoc/index.rst not found I hope that my preliminary work might be helpful for the package but I have to give up now due to time constraints. Hope this helps Andreas. -- http://fam-tille.de
