JupyterLab 4.1 includes a number of new features (described below), 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.
Custom CSS
Jupyterlab now supports automatic loading of custom CSS.
Themes are the recommended way for customizing the JupyterLab look and feel,
while custom CSS is intended for minor personal adjustments.
To opt in, start JupyterLab with the --custom-css flag.
The location of the custom.css file is documented in the section on customizing the user interface.
`custom.css` is also available in Jupyter Notebook;
while similar selectors can be used for components shared between JupyterLab 4.1 and Jupyter Notebook 7.0,
there was a different set of selectors in Notebook 6 and older versions.
Users with the custom CSS file using the selectors from legacy Notebook versions
will need to update them and note that tutorials may refer to the selectors for the old Notebook versions.
Diagrams in Markdown
Matching GitHub-Flavoured Markdown, JupyterLab 4.1 now supports Mermaid diagrams.
To create a mermaid diagram use the mermaid language specifier for a code block in a markdown cell or document, for example:
```mermaid
flowchart LR
A[Hard] -->|Text| B(Round)
B --> C{Decision}
C -->|One| D[Result 1]
C -->|Two| E[Result 2]
</code></pre>
<p>which renders as:</p>
<!-- raw HTML omitted -->
<h3>Inline completer</h3>
<p>JupyterLab now supports completion presented as ghost text in the cell and file editors,</p>
<!-- raw HTML omitted -->
