👀 What Changed

Python 3.13 is out and Python 3.8 has reached end-of-life. Hence, this release drops support for Python 3.8 and includes Python 3.13 wheels (including the free-threading Python variant).

Additionally, this is the first release with Linux wheels based on manylinux_2_28 instead of manylinux2014. This means generally faster performance for the package on Linux.

This is also the first release including a uv.lock file for reproducible, working Python environments. This includes switching from dependabot to renovate for automatically managing dependency updates.

Finally, this release contains a couple of convenience updates for MQT DDSim.

👀 What Changed

This release switches the project from setuptools to the modern scikit-build-core. This brings a way better development experience with faster editable rebuilds, no more setup.py and MANIFEST.in files, and more. See #283 for some more details.

It also switches the CI to the reusable workflows introduced in MQT Core, which is (more-and-more) truly becoming the backbone of the MQT. Build caching is now enabled for all CI workflows, change detection only runs those flows that are required for the given changes, PyPI publishing uses trusted publishing now, and many more. Also see #283 for more details.
