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

Snyk changed the following file(s):

  • packages/documentsearch-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.

Merge Risk: High

This upgrade includes a significant and high-risk major version update for @jupyter-notebook/application and a low-risk stabilization update for @jupyterlab/documentsearch.

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

The upgrade to Jupyter Notebook 7 represents a fundamental architectural shift. The application is now built using JupyterLab components, which introduces significant breaking changes, especially for extensions and customizations.

Key Breaking Changes:

  • New Architecture: Notebook 7 is based on JupyterLab, sharing its codebase and extension system. The previous extension ecosystem is not compatible.
  • Extension Incompatibility: Classic Notebook extensions (for versions 6.x and earlier) will not work with Notebook 7. Developers must find updated extensions or replacements.
  • UI and UX Changes: While aiming to preserve the document-centric feel, the UI has been redesigned and now includes features like a debugger, real-time collaboration, and a table of contents by default.

Recommendation:
This is a high-risk upgrade that will likely break existing customizations and extensions. Before merging, verify if any custom extensions are in use. If so, a migration plan is required. For maintaining compatibility with older workflows, the project team provides nbclassic, a package that can be used to serve the classic Notebook 6 interface.

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

This is a low-risk update, moving from a pre-release (alpha) to a stable version. This type of change typically includes bug fixes and API stabilization rather than introducing new breaking changes. The significant API rework for this package occurred during the major version upgrade to JupyterLab 4.0, not within this minor version release.
