Compatibility

JupyterLab Version Support

This extension is compatible with JupyterLab 4.4.0 or higher. It requires the content provider registry API introduced in JupyterLab 4.4.

Upper bound: The extension sets an upper bound of < 5.0.0 to prevent automatic installation with potentially incompatible future major versions of JupyterLab.

Maintenance Policy

Following JupyterLab's extension development guidelines, we adhere to semantic versioning principles:

• Major releases (e.g., 1.0.0 → 2.0.0): May introduce breaking changes and require user action
• Minor releases (e.g., 1.0.0 → 1.1.0): Add new features while maintaining backwards compatibility
• Patch releases (e.g., 1.0.0 → 1.0.1): Bug fixes and minor improvements only

When JupyterLab 5.x is released, we will:

1. Evaluate the changes and update the extension as needed
2. Release a new major or minor version with explicit JupyterLab 5.x support
3. Clearly document any breaking changes in the changelog

Backwards Compatibility

This extension follows semantic versioning for its own API:

• Current version (0.x.x): Pre-release phase. APIs may change without prior notice.
• Version 1.0.0 onwards: We will maintain backwards compatibility within major versions and clearly document breaking changes between major versions.

Note: This extension does not support JupyterLab 3.x or earlier versions.
