The latest release introduces enhanced formatting features, including support for indexed expressions and improved Image3D rendering using maximum intensity projection. The REST API has been added to enable broader functionality for developers. Additionally, the integration of the WebUI Framework with WLX enables building complex applications directly within the notebook environment.

This release introduces a debugger integrated into the command palette for monitoring symbol changes during kernel evaluation and creating standalone widgets with isolated resources using WLJS Notebook. Other updates include enhanced SystemDialogInput for file operations, background sound emitting, InputAutocomplete for async suggestions, WebGL performance improvements, and better handling of large formatted outputs.

This update introduces enhanced support for SummaryBox, including proper representation of ResourceFunction and related elements. GraphicsComplex has been improved to support additional primitives like Tube, Sphere, and Line, with optimized performance for Tube geometry and dynamic updates for both coordinates and radius.

New features include the ability to export entire notebook folders as compressed files for easy sharing, import functionality for reusing symbols and templates across notebooks, and the introduction of TabView for intuitive tab-based visualizations. Additionally, dialog tools such as ChoiceDialog and MessageDialog have been added for interactive user prompts.

This update brings significant improvements, including autocomplete enhancements that dynamically load suggestions for symbols from external packages by rescanning $ContextPath. The UI for Windows and Linux has been simplified with a redesigned main menu to resemble native apps more closely.

Additionally, a new approach for dynamically adding graphics primitives to existing canvas objects is introduced, bypassing immutability through FrontInstanceReference. Enhanced Manipulate support now includes implicit selection forms and localized symbols.

This update introduces a better folder structure, relocating notebooks, backups, and examples to logical directories like YourDocuments/WLJS Notebooks and $TemporalDirectory while preserving current data and streamlining offline documentation access. Improved file synchronization prevents crashes during large uploads by splitting data into smaller parts, while new visualization tools enhance image and vector graphics integration, dynamic tracking, animated image support, and interactive raster editing.

Additionally, shell access for Unix/OSX users allows direct command execution, and ESM JavaScript cells enable seamless integration of NPM libraries like siriwave, providing in-place compilation with esbuild for enhanced development flexibility.

This release enhances 3D rendering with GraphicsComplex now supporting VertexNormals for improved lighting accuracy and dynamic geometry options in Polygon for creating complex shapes. Developer tools are improved with shared JavaScript libraries, a global CLI for easy notebook access, and streamlined cell evaluation and management features.
