[anaconda-security-bot]

Snyk has created this PR to fix 1 vulnerabilities in the yarn dependencies of this project.

Snyk changed the following file(s):

• packages/docmanager-extension/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.

🦉 Directory Traversal

[anaconda-security-bot]

This update involves a major, high-risk upgrade for @jupyter-notebook/application and a low-risk patch for @jupyterlab/docmanager.

@jupyter-notebook/application: 0.0.0-use.local → 7.0.0 (High Risk)

This is a significant and breaking upgrade. Jupyter Notebook 7 is a complete architectural rewrite based on the JupyterLab codebase.

Key Breaking Changes:

• Extension Incompatibility: Classic Jupyter Notebook (v6 and older) extensions are not compatible with Notebook 7. Your development workflow will break if you rely on any classic extensions. You must migrate to or find replacements in the JupyterLab extension ecosystem.
• New Codebase: While the UI aims to preserve the classic document-centric feel, the underlying application is entirely different, inheriting many features from JupyterLab like a visual debugger, real-time collaboration, and improved theming.
• API Changes: Due to the new architecture, any integrations that relied on the classic Notebook's frontend components or APIs will be broken.

Recommendation:
This upgrade cannot be handled casually. A full audit of required extensions is necessary. Treat this as a migration to a new platform (from Classic Notebook to a JupyterLab-based Notebook) and plan for significant testing and potential refactoring of custom tools.

@jupyterlab/docmanager: 4.5.0-alpha.3 → 4.5.0 (Low Risk)

This is a low-risk update from a pre-release to the final version. It consists primarily of bug fixes and stabilization and introduces no breaking changes.
