+Added a start page for the extension. Launched in experimental mode such that it opens to new users or when there is a new release. It can be disabled with the setting 'Python: Show Start Page' and it can be opened at any time with the command 'Python: Open Start Page'.
+Removed `python.jediEnabled` setting in favor of `python.languageServer`. Instead of `"python.jediEnabled": true` please use `"python.languageServer": "Jedi"`.
+Made the variable explorer in the Notebook editor resizable.
