Version 1.14.2

Fixed

• The sample notebooks have been normalized with nbformat.validator.normalize (#1002).
• The warnings in the test suite that we cannot fix are filtered using a new pytest.ini file
• We updated the yarn.lock file for the jupyter lab extension to address security vulnerabilities (#984, #1005, #1011)

Changed

• The CI uses Python 3.9 rather than 3.7 when testing conda environments

Added

• Gnuplot is now supported (#998) - thanks to razimantv for this contribution
• We now test Jupytext against Python 3.6 to 3.11 on the CI
• We have added a test to document how to use the folder and prefix matching when pairing notebooks (#974)

Version 1.14.1

Fixed

• The timestamp of a paired notebook is the timestamp of the most recent paired file. This fixes the warning "File Changed" after reloading the notebook in Jupyter (#978).

Version 1.14.0

Changed

• The Jupytext configuration file has a new option cm_config_log_level that defaults to info_if_changed.
  With that value, the contents manager will log a line regarding the configuration file used only when the
  config file is not the same as the one previously used (#959) -
  many thanks to R.C. Thomas for suggesting this and thoughtfully testing the patch.
• Hidden configuration files like .jupytext.toml or .jupytext.py are now ignored by Jupytext's contents manager
  when allow_hidden=False (that option was introduced in jupyter_server==2.0.0a1) (#964).
• We have changed jupytext --set-formats to make it more similar to jupytext --sync. Now --set-formats will not
  override existing paired files anymore (#969).

Added

• We have added a test test_pre_commit_hook_sync_with_no_config that documents how to use the pre-commit hook without
  a configuration file (#967)

Version 1.13.8

Fixed

• Text-only notebooks are always trusted (as they don't include any output cells) (#941)
• We made sure that our tests also work in absence of a Python kernel (#906)
• The coverage of the tests folder has been restored at 100%
• Bash commands like !{cmd} are now correctly escaped in the py:percent format (#938)

Added

• Added Tcl as a supported language (#930) - thanks to shishitao for this contribution
• Added Maxima as a supported language (#927) - thanks to Alberto Lusiani for contributing a sample Maxima notebook.

Changed

• The Jupytext contents manager is derived from the LargeFileManager imported from jupyter_server rathen than notebook (#933)
• Allow for markdown-it-py v2 (#924)
• We have updated the hooks used in the test pre-commits, to fix an issue on the CI (#940, #942)
• We updated the yarn.lock file for the jupyter lab extension (#904, #925, #935, #939)

Version 1.13.7

Fixed

• The Jupytext CLI only suggest --update when the target is an .ipynb file (#905) - thanks to st-- for this contribution
• We made sure that commands like cat notebook.md | jupytext --execute work (#908)

Added

• Added Haskell as supported language (#909) - thanks to codeweber for this contribution

Changed

• We have updated the pre-commit hooks and in particular we switched to the first stable version of black==22.1.0.
• We require pandoc==2.16.2 for testing. The representation for code cells changed from ``` {.python} to ``` python in that version of Pandoc (#906). We don't use pandoc>=2.17 in tests at the moment because of the introduction of cell ids that cannot be filtered.
• Jupytext will not add anymore a UTF-8 encoding on Python scripts when the notebook contains non-ascii characters (#907)
• We have added pyupgrade to the pre-commit hooks used for developing Jupytext (#907)

Version 1.13.6

Fixed

• The text_representation metadata of text notebooks is filtered from .ipynb files both in jupytext.write and in the contents manager for Jupyter (#900)

Changed

• Jupytext will not issue a warning when a format suffix starting with '.', '-' or '_' is passed to the --to option (#901)

Version 1.13.5

Fixed

• Jupytext will not open a text notebook that is not UTF-8 (#896)
• Fixed typo in git tag (#899)

Version 1.13.5

Fixed

• Jupytext will not open a text notebook that is not UTF-8 (#896)

Version 1.13.4

Changed

• The test suite filters the warnings that don't belong to Jupytext (#823)

Fixed

• The parsing of notebooks that don't have a YAML header (like docs/formats.md) was improved.
• The test suite works with pytest-randomly (#838)

Version 1.13.3

Changed

• The "Jupytext Notebook" factory that lets the user configure the Notebook viewer as the default for text notebooks accepts more filetypes: "myst", "r-markdown" and "quarto" (#803)
• Empty MyST Markdown files are valid notebooks (#883)
• Jupytext also works with markdown-it-py v2.0 (#885)
