Changelog

A summary of changes in the Jupyter notebook. For more detailed information, see GitHub.

Use pip install notebook --upgrade or conda upgrade notebook to upgrade to the latest release.

We strongly recommend that you upgrade pip to version 9+ of pip before upgrading notebook.

Use pip install pip --upgrade to upgrade pip. Check pip version with pip --version.

7.6

Jupyter Notebook 7.6 is based on JupyterLab 4.6, and includes a number of new features, bug fixes, and enhancements for extension developers. This release is compatible with extensions supporting JupyterLab 4.0. Extension authors are recommended to consult the Extension Migration Guide which lists deprecations and changes to the public API.

Below are a few highlights for this new release. Most of the new features and improvements come from the update to JupyterLab 4.6, although they may not all be supported in Notebook 7.6.

For reference you may have a look at the JupyterLab 4.6 changelog to learn more.

Scratchpad console

A scratchpad console can now be opened next to a notebook, sharing the same kernel. This makes it easy to run quick experiments or inspect variables without modifying the notebook itself.

The scratchpad console can be opened from the File -> New -> Scratchpad console menu, from the command palette, or with the Ctrl + B (or Cmd + B on macOS) keyboard shortcut, which toggles the console panel.

Confirmation dialog when closing and shutting down a notebook

The "Close and Shut Down Notebook" command now asks for confirmation before closing the browser tab and shutting down the kernel. The confirmation prompt can be disabled in the Settings Editor with the "Prompt for confirmation before closing and shutting down" setting.

Notebook improvements

• The cell toolbar delete button now shows a confirmation dialog to prevent accidental deletion. The "Do not ask me again" preference is persisted in the Cell Toolbar settings. The D, D keyboard shortcut is unaffected.
• A new "Paste code cells without output" setting strips outputs and execution counts from code cells when pasting, producing clean cells without outputs which may be stale or untrusted.
• Copy, cut, and paste text commands have been added to the notebook context menu. This feature requires permission to access the clipboard and may not work in Firefox depending on version and additional restrictions.
• Two new navigation commands, "Select Last Modified Cell" and "Select Next Modified Cell", allow jumping back and forward through recently edited cells. They are available from the command palette and as buttons in the Table of Contents toolbar.
• Pressing Ctrl + B (or Cmd + B on macOS) while editing a Markdown cell wraps the selected text in bold formatting.
• When exporting a notebook as HTML via File -> Save and Export Notebook As -> HTML, a dialog now asks whether to sanitize the HTML output before download.

Looks like notebook is no longer a dependency, so this is no longer needed.
