[anaconda-security-bot]

Snyk has created this PR to fix 2 vulnerabilities in the yarn dependencies of this project.

Snyk changed the following file(s):

• packages/_metapackage/package.json

Note for zero-installs users

If you are using the Yarn feature zero-installs that was introduced in Yarn V2, note that this PR does not update the .yarn/cache/ directory meaning this code cannot be pulled and immediately developed on as one would expect for a zero-install project - you will need to run yarn to update the contents of the ./yarn/cache directory.
If you are not using zero-install you can ignore this as your flow should likely be unchanged.

⚠️ Warning

Failed to update the yarn.lock, please update manually before merging.

This is a major upgrade to Jupyter Notebook 7, which is a complete architectural rewrite based on JupyterLab components. This introduces significant breaking changes, primarily affecting the extension system.

Key Breaking Changes:

• New Extension System: Classic Jupyter Notebook (v6 and older) extensions are not compatible with Notebook 7. All extensions must now be compatible with the JupyterLab extension system. If you have custom frontend extensions, they will need to be migrated.
• New Codebase: The packages @jupyter-notebook/help-extension, @jupyter-notebook/lab-extension, and @jupyter-notebook/ui-components are part of the new JupyterLab-based frontend. Upgrading to 7.0.0 means adopting this entirely new application framework.
• UI and Behavior Changes: While designed to maintain the classic document-centric feel, the user interface has been updated. It now uses the CodeMirror 6 editor and inherits many new features from JupyterLab, such as a visual debugger, theming, and a table of contents.

Recommendation:
This upgrade requires a thorough review and likely a significant migration effort, especially if you rely on custom frontend extensions. Before merging, verify that all necessary extensions have a compatible version for JupyterLab/Notebook 7 or plan for the development work to port them.
