Here's the what is currently listed there.

• Removed python.jediEnabled setting in favor of python.languageServer. Instead of "python.jediEnabled": true please use "python.languageServer": "Jedi".
• Integrate VS Code experiment framework in the extension.
• Added a start page for the extension. It opens to new users or when there is a new release. It can be disabled with the setting 'Python: Show Start Page'.
• Preliminary support using other languages for the kernel.
• Enable the use of the custom editor for native notebooks.

Here's suggestion:

• Added a start page for the extension. It opens to new users or when there is a new release. It can be disabled with the setting 'Python: Show Start Page'.
• Removed python.jediEnabled setting in favor of python.languageServer. Instead of "python.jediEnabled": true please use "python.languageServer": "Jedi".
• Integrate VS Code experiment framework in the extension.
• Experimental support for editing notebooks in languages other than Python.
  - Enable the use of the custom editor for native notebooks.

Here are my justifications.

• It seems odd to mention the start page as the third item in the list since the user is already reading it. Either it should be the first item, the last item, or mentioned separately in an intro paragraph of some sort..
• I'd prefer to say that we experimentally are enabling languages other than Python for notebooks.
• Custom editor is behind an experiment.
