Jupytext

-------------------

**Fixed**
- Format options stored in the notebook itself are now taken into account (Fixes [757](https://github.com/mwouts/jupytext/issues/757))

-------------------

**Fixed**
- The `jupytext.toml` config file can now be used together with the `jupytext` pre-commit hook ([752](https://github.com/mwouts/jupytext/issues/752))
- The `notebook_extensions` option of the `jupytext.toml` file now works ([746](https://github.com/mwouts/jupytext/issues/746))

**Changed**
- The options in `jupytext.toml` where renamed to match the `jupytext` metadata in the text notebooks. One should now use `formats` rather than `default_jupytext_formats` and `notebook_metadata_filter` rather than `default_notebook_metadata_filter` ([753](https://github.com/mwouts/jupytext/issues/753))

-------------------

**Fixed**
- We have updated `marked`, an indirect dependency of the `jupyterlab-jupytext` extension, to fix a moderate vulnerability ([750](https://github.com/mwouts/jupytext/issues/750)).
- We use non-random cell ids in the tests to avoid test failures due to duplicate cell ids ([747](https://github.com/mwouts/jupytext/issues/747))

-------------------

**Fixed**
- We have adjusted the `MANIFEST.in` file to exclude the `node_modules` but still include the JupyterLab extension that was missing in the `.tar.gz` (and conda) package in v1.10.1. Many thanks to Martin Renou for providing the fix at ([741](https://github.com/mwouts/jupytext/issues/741))

-------------------

**Added**
- The recursive glob pattern `**/*.ipynb` is now supported by Jupytext - Thanks to Banst for this contribution ([731](https://github.com/mwouts/jupytext/issues/731))
- Sage notebooks are supported. They can be converted to `.sage` and `.md` files and back. Thanks to Lars Franke for suggesting this! ([727](https://github.com/mwouts/jupytext/issues/727))
- Jupytext is also accessible with `python -m jupytext`. Thanks to Matthew Brett for his PR! ([739](https://github.com/mwouts/jupytext/issues/739))

**Changed**
- We have tested Jupytext with the new cell ids introduced in `nbformat>=5.1.0`. Cell ids are preserved by the `--sync` and `--update` command. So we removed the constraint on the version of `nbformat` ([735](https://github.com/mwouts/jupytext/issues/735)).

**Fixed**
- We filtered out the `node_modules` folder from the `.tar.gz` package for Jupytext ([730](https://github.com/mwouts/jupytext/issues/730))

-------------------

**Added**
- Jupytext has a pre-commit hook! Many thanks to John Paton and Aaron Gokaslan for making this happen ([698](https://github.com/mwouts/jupytext/issues/698))
- Jupytext CLI will not rewrite files that don't change ([698](https://github.com/mwouts/jupytext/issues/698)).
- If you want to see the diff for changed files, use the new `--diff` option ([722](https://github.com/mwouts/jupytext/issues/722))
- We have added `isort` and `autoflake8` to the `pre-commit` configuration file used for developing the Jupytext project ([709](https://github.com/mwouts/jupytext/issues/709))
- We made sure that `py:percent` scripts end with exactly one blank line ([682](https://github.com/mwouts/jupytext/issues/682))
- We checked that Jupytext works well with symbolic links to folders (not files!) ([696](https://github.com/mwouts/jupytext/issues/696))

**Changed**
- Jupytext does not work properly with the new cell ids of the version 4.5 of `nbformat>=5.1.0` yet, so we added the requirement `nbformat<=5.0.8` ([715](https://github.com/mwouts/jupytext/issues/715))
- Jupytext will issue an informative error or warning on notebooks in a version of nbformat that is not known to be supported ([681](https://github.com/mwouts/jupytext/issues/681), [#715](https://github.com/mwouts/jupytext/issues/715))

**Fixed**
- Code cells that contain triple backticks (or more) are now encapsulated with four backticks (or more) in the Markdown and MyST Markdown formats. The version number for the Markdown format was increased to 1.3, and the version number for the MyST Markdown format was increased to 0.13 ([712](https://github.com/mwouts/jupytext/issues/712))
- Indented magic commands are supported ([694](https://github.com/mwouts/jupytext/issues/694))
