jupytext 1.19.5

Version 1.19.5

on Python PyPI

Changed

• Harden the github action (#1569). Thanks to Peyton Murray for this PR
• The JupyterLab extension is now built with jupyter-builder - Thanks to Mahendra Paipuri for this PR (#1590)
• zizmor and pre-commit are now required to pass before any other CI job runs, and the extension lint is now part of pre-commit (#1594)
• Enabled TypeScript strict null checks in the JupyterLab extension - Thanks to Michał Krassowski for this PR (#1586)

Fixed

• Detecting IPython help/shell commands no longer takes quadratic time on lines made of whitespace - Thanks to Naveed for this PR (#1582)
• Fixed unguarded access to the languageInfo.extensions array, which could still make Jupytext show notebook icons for Python files when the kernel metadata was incomplete - Thanks to Michał Krassowski for this PR (#1584)

Security

• marimo_py_to_notebook now reuses its secure (0600, mkstemp-backed) temporary files instead of closing and reopening them by name, which removed the safe permissions and left a window for a symlink attack on shared machines (#1568). Thanks to Naveed for reporting and fixing this!
