Version 1.2.1

Improvements

• Added documentation on how to use Jupytext with JupyterLab 0.35 (#299)
• and on using Jupytext with the pre-commit package manager (#292)
• The read and write functions are easier to use (#292)

BugFixes

• Jupytext now ships the jupyterlab-jupytext extension in version 1.0.2. The version 1.0.1 erroneously introduces a target_formats metadata in the jupytext section, instead of formats, and works only after two clicks.
