User-facing changes

• Display the extension manager in the left sidebar by default. Users will need to acknowledge the disclaimer in the extension manager before using it. (#8050, #8145)
• Added blacklist and whitelist support <extension_listings> for the extension manager (#7989)
• Automatically link URLs in notebook output text (#8075, #7393)
• Added a "Restart Kernel and Run All Cells..." button to the notebook toolbar (#8024)

• Added a context menu item for opening a Markdown editor from the Markdown preview (#7942)

• Support Node.js 10+ (#8112, #8083)

• Added a command to replace the selection in an editor with text (inserting if there is no selection). This can be assigned a keyboard shortcut, as shown below. We also added a command to go through a series of commands and run the first enabled command. (#7908) Here is a keyboard shortcut to insert text in a currently-active notebook editor:

  {
    command: "notebook:replace-selection",
    selector: ".jp-Notebook",
    keys: ["Ctrl L"],
    args: {text: "lambda x: x"}
  }
  

  Here is a keyboard shortcut to insert text into an editor of the currently active console, file editor, or notebook:

  {
    command: "apputils:run-first-enabled",
    selector: "body",
    keys: ["Ctrl L"],
    args: {
      commands: [
        "console:replace-selection",
        "fileeditor:replace-selection",
        "notebook:replace-selection",
      ],
      args: {text: "lambda x: x"}
    }
  }
