## 7.5
Jupyter Notebook 7.5 is based on JupyterLab 4.5, and includes a number of new features, 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](https://jupyterlab.readthedocs.io/en/latest/extension/extension_migration.html#jupyterlab-4-4-to-4-5) which lists deprecations and changes to the public API.
Below are a few highlights for this new release. Most of the new features and improvements come from the update to JupyterLab 4.5, although they may not all be supported in Notebook 7.5.
For reference you may have a look at the [JupyterLab 4.5 changelog](https://jupyterlab.readthedocs.io/en/latest/getting_started/changelog.html#v4-5) to learn more.
### Notebook improvements
The default windowing mode is now `contentVisibility` which improves cell rendering and alleviates previously reported issues. The minimap can be enabled for all windowing modes and all notebooks via the `Settings` menu, or by toggling the minimap per notebook with the `View` -> `Show Minimap` option.
Additional fixes improve layout containment and scrollbar behavior when working with long cells.
### Debugger and console enhancements
The debugger's evaluate dialog has been replaced with an interactive console featuring syntax highlighting and code completion. The variables panel now preserves state when switching editors. Visual improvements include highlighted selected breakpoints, improved empty line handling, and a paused indicator. Debugger panels now reference cell execution counts.

- There is a new `allowFileUploads` setting to control upload permissions.
- Menu options for creating Python, R, or Julia files are now available from the New menu.
- The "Select All" command is now available with the Ctrl + A (or Cmd + A on macOS) keyboard shortcut in the file browser.
- Breadcrumbs are now configurable through `breadcrumbsLeftItems` and `breadcrumbsRightItems` settings.
### Settings editor improvements
The `addExtraLineOnCellMerge` setting removes extra lines when merging cells, matching classic notebook behavior.
### Cell toolbar settings
The cell toolbar settings are now exposed in the Settings Editor, making it easier to customize the cell toolbar appearance and behavior.
### Keyboard shortcuts
The `O` key has been defined as the keyboard shortcut to toggle cell outputs, restoring this familiar functionality from the classic notebook.
### User interface and accessibility
Automatic theme switching between light and dark modes is now available when system synchronization is enabled. Dialog components display buttons and checkboxes on separate lines for improved readability. Terminal selections show better visibility under high-contrast themes. Keyboard navigation and status bar tab ordering have been improved.
### Breaking changes
Python 3.8 support has been dropped in this release.
