Jupytext

----------

**Changed**
- Jupytext's default contents manager is now derived from the asynchronous AsyncLargeFileManager. Thanks to [Darshan Poudel](https://github.com/Darshan808) for making this finally happen ([#1328](https://github.com/mwouts/jupytext/pull/1328))!
- The MyST frontmatter found in MyST Markdown notebooks is now mapped to a YAML header at the top of the Jupyter notebook. This way MyST notebooks in either the `md:myst` or `ipynb` format can be used with MyST. Thanks to [Ian Carroll](https://github.com/itcarroll) for proposing and implementing this change ([#1314](https://github.com/mwouts/jupytext/issues/1314))
- The [percent format](https://jupytext.readthedocs.io/en/latest/formats-scripts.html#the-percent-format) is now the default format for scripts. If you run `jupytext --to py notebook.ipynb` you now get a `py:percent` script (use `--to py:light` for the light format) [1201](https://github.com/mwouts/jupytext/pull/1201)
- The `rst2md` conversion now works with `sphinx-gallery>=0.8`. Thanks to [Thomas J. Fan](https://github.com/thomasjpfan) for fixing this! ([#1334](https://github.com/mwouts/jupytext/pull/1334))
- We have updated the JupyterLab extension dependencies ([1300](https://github.com/mwouts/jupytext/pull/1300), [#1355](https://github.com/mwouts/jupytext/pull/1355), [#1360](https://github.com/mwouts/jupytext/pull/1360)). Thanks to [Mahendra Paipuri](https://github.com/mahendrapaipuri) for these PRs!

**Added**
- The context menu has a "New Text Notebook" entry. Thanks to [Mahendra Paipuri](https://github.com/mahendrapaipuri) for this PR ([#1365](https://github.com/mwouts/jupytext/pull/1365))!

**Fixed**
- We have added and fixed round trip tests on MyST Markdown notebooks ([759](https://github.com/mwouts/jupytext/issues/759), [#789](https://github.com/mwouts/jupytext/issues/789), [#1267](https://github.com/mwouts/jupytext/issues/1267), [#1317](https://github.com/mwouts/jupytext/issues/1317))
- The `--quiet` option now works with the `--pipe` mode of Jupytext CLI ([1305](https://github.com/mwouts/jupytext/issues/1305))
- Jupytext is now compatible with the cell toolbar extension - thanks to [Nicolas Brichet](https://github.com/brichet) for the fix! ([#1358](https://github.com/mwouts/jupytext/pull/1358))
- The project description on PyPI now uses absolute links ([1287](https://github.com/mwouts/jupytext/issues/1287))

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

**Added**
- Logtalk notebooks are now supported ([1308](https://github.com/mwouts/jupytext/pull/1308)) - thanks to [Paulo Moura](https://github.com/pmoura) for this contribution

**Fixed**
We have updated the dependencies of the JupyterLab extension to address [security issues](https://github.com/mwouts/jupytext/security/dependabot).

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

**Fixed**
- We fixed a "File Changed" warning when saving notebooks ([1301](https://github.com/mwouts/jupytext/issues/1301))

**Changed**
- The original file name is easier to infer from the tmp file name in pre-commit hooks ([1289](https://github.com/mwouts/jupytext/issues/1289)) - thanks to [Lunin Leonid](https://github.com/lrlunin) for making this change.

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

**Fixed**
- We have fixed a notebook corruption issue when using Jupytext with Jupyter-Collaboration ([1124](https://github.com/mwouts/jupytext/issues/1124), [jupyter-collaboration 214](https://github.com/jupyterlab/jupyter-collaboration/issues/214)).
- We have added the `require_hash` argument on the Jupytext contents manager. The hash of a paired file is the concatenation of the hash of the text file and the hash for the `.ipynb` file ([1165](https://github.com/mwouts/jupytext/issues/1165))
- The `rst2md` tests have been fixed by requiring `sphinx<8` ([1266](https://github.com/mwouts/jupytext/issues/1266))
- Some dependencies of the JupyterLab extensions were updated ([1272](https://github.com/mwouts/jupytext/issues/1272), [#1273](https://github.com/mwouts/jupytext/issues/1273), [#1280](https://github.com/mwouts/jupytext/issues/1280), [#1285](https://github.com/mwouts/jupytext/issues/1285), [#1290](https://github.com/mwouts/jupytext/issues/1290))
- The pre-commit hook is now compatible with log.showsignature=True ([1281](https://github.com/mwouts/jupytext/issues/1281)). Thanks to [Justin Lecher](https://github.com/jlec) for this fix.

**Added**
- Jupytext is now tested with Python 3.13 ([1242](https://github.com/mwouts/jupytext/issues/1242)). Thanks to [Jerry James](https://github.com/jamesjer) for the suggested fixes!
- The extension of a notebook piped into stdin will be taken in the notebook metadata ([1282](https://github.com/mwouts/jupytext/issues/1282))

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

**Fixed**
- We use `asyncio.iscoroutinefunction` to determine whether the current contents manager is sync or async ([1260](https://github.com/mwouts/jupytext/issues/1260))

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

**Fixed**
- We use `inspect` to determine whether the current contents manager derives from `AsyncContentsManager` (which is not
supported by Jupytext at the moment). This fixes a compatibility issue with `jupyter-fs==1.0.0` ([1239](https://github.com/mwouts/jupytext/issues/1239)). Thanks to [Mahendra Paipuri](https://github.com/mahendrapaipuri) for this PR!
- We have fixed a typo when `build_jupytext_contents_manager_class` can't be imported ([1162](https://github.com/mwouts/jupytext/issues/1162))
- A Python 3.13 deprecation warning was fixed [1241](https://github.com/mwouts/jupytext/pull/1241) - thanks to [Jerry James](https://github.com/jamesjer)
- We have fixed a typo when `build_jupytext_contents_manager_class` can't be imported ([1162](https://github.com/mwouts/jupytext/issues/1162))
- Some dependencies of the JupyterLab extensions were updated ([1243](https://github.com/mwouts/jupytext/issues/1243), [#1245](https://github.com/mwouts/jupytext/issues/1245))

**Added**
- Lua notebooks are now supported ([1252](https://github.com/mwouts/jupytext/pull/1252)) - thanks to [erentar](https://github.com/erentar) for this contribution
- Go notebooks are supported too ([1244](https://github.com/mwouts/jupytext/issues/1244))! Many thanks to [Jan Pfeifer](https://github.com/janpfeifer), author of [GoNB](https://github.com/janpfeifer/gonb), and to [HaveF](https://github.com/HaveF) for their help on this topic.
- Empty prefixes are now allowed in Jupytext format when specified as a dictionary ([1144](https://github.com/mwouts/jupytext/issues/1144))

**Changed**
- We've had to deactivate the tests on the Quarto format in the CI as the Quarto round trip
might now add a Markdown cell to the notebook ([1255](https://github.com/mwouts/jupytext/issues/1255))
