3.18.0

3.18.0 - 2026-05-21

Changed

• Switch deprecated ghostnet to shadownet as default network.
• Migrate dependency management from Poetry to uv. pyproject.toml now uses PEP 621 [project] and PEP 735 [dependency-groups]; build backend is hatchling; lockfile is uv.lock. The notebook dependency moved to a jupyter extra (installed in the michelson-kernel Docker image, not in pytezos). Dockerfiles consume uv.lock directly via bind mounts; the generated requirements*.txt files were removed.
• Breaking: pip install pytezos no longer ships the Jupyter stack as a side effect. To use the michelson-kernel console script, install with the extra: pip install pytezos[jupyter]. Pre-3.18 the same effect happened transitively through notebook being a top-level runtime dependency.
• Bump notebook constraint to >=7,<8. Notebook 6.x called from distutils.version import LooseVersion, which broke after Python 3.12 removed distutils; the michelson-kernel Docker image (Python 3.12) could not launch since that upgrade. Notebook 7 is built on jupyter-server and works on Python 3.12+. Removed the now-unrecognised --no-mathjax flag from the image's jupyter-notebook entrypoint.
