v2.8.8

• Polished native GUI on all platforms with system accent color support and customization in Settings.
• Reimplemented Input / InputString with async variants (InputAsync, InputStringAsync) for interactive input; added simple ProgressIndicator (supports dynamic symbols).
• Improved text rendering in graphics: Text can inset symbolic numeric expressions (e.g., 1/2, Exp[...], Sqrt[...])—note: dynamics only for strings.
• Shortcuts updates: new evaluate-and-jump shortcut (Ctrl/CMD+Enter)
• Fix #453
• Fix #459
• Update on #458 and related #426
• AppImage added for GNU/Linux!

2.8.7

• laser pointer on slides improved; press q to toggle;
• new Print to PDF feature for notebooks, including manual page breaks via PageBreakAbove/PageBreakBelow;
• paclet extensions: ship JS/CSS assets, write one package for WLJS/Mathematica/WolframScript, assets embed/cached in exported notebooks;
• Graphics & media: fixes to 2D aspect/arrows/curves;
• AnimatedImage exportable to HTML/MDX;
• easy GIF/video export from Animate;
• DEV & UX: async RasterizeAsync/ExportAsync;
• better clipboard options (ClickToCopy, Paste, CopyToClipboard);
• fixed maximize bug on Windows machines;
• moved to new ElectronJS version 32 (2023) -> 38 (2025);
• add support for Style[..., Bold] in the context of 2D and 3D graphics;
• Disk issue #449;
• arrows and spline curves fix #448;
• improved LPM (package manager), added support for .paclets;
• fixed lighting bugs with PointLight, SpotLight, extended options are provided;
• docker image now got Clang build tools installed to work with Compile and LibraryLink;
• fixed bug with "magic cells";
• build-in terminal improvements;
• Windows binaries now digitally signed via SignPath.

2.8.5

• App Integrity: Core packages/modules moved from AppData into the app folder (immutable); only small personal settings stored outside. Initialization simplified and several hundred LOC removed. Updates now occur globally (no per-module local updates).
• Excalidraw Images: Whiteboards in markdown/slide cells now support drag-and-drop image files; images are embedded as base64 in notebook storage.
• Event-Driven Animations: New pattern for AnimationFrameListener makes it easier to attach handlers and frame triggers for interactive graphics.
• Subscripts in Manipulate: Fixed pipeline so Subscript parameters work in Manipulate/Animate expressions (e.g., Subscript[f, C]).
• 2D Graphics: Improved rendering/behavior .
• Graphics3D: Broader support for 3D plots.
• FormalA-Z, ScriptA-Z, DoubleStruckA-z named symbols support

Issues addressed

• #443
• #429
• #440
• #437
• #442

2.8.4

Hot Fix

• ⚠️ fixes an issue #434 (antimalware false alarm)
• plot directives (Thick, Dashed and etc) #438
• AnimatePlot issue #430
• web API extension update
• slide cells minor bugs were fixed
• missing Refresh output form for slides

2.8.3

Summary:

• Labels now behave more like Mathematica, supporting StandardForm, Automatic, offsets, LaTeX cells, and even custom WLJS functions.
• Improved slides export using custom ElectronJS-based PDF renderer.
• Correct rendering of standard forms like Complexes, Reals.
• Added TableAsync and DoAsync, allowing asynchronous versions of Table/Do.
• Better handling of 2D/3D plots with very large numbers of points (via WebGL OES_element_index_uint).
• Assistant plugin can now connect to locally running LLMs (e.g., Ollama), not just OpenAI models.
• Fixed missing AnimationRate and RefreshRate options in animations.
• Improved Windows network I/O stability and fixed minor bugs.

2.8.2

• Fixed breaking changes in built-in symbol outputs after WL 14.3, added a UI update separating input/output cells, and expanded styling options with new CSS classes for customization.
• Introduced a JIT transpiler for Refresh, plus new examples including Arduino hardware integration and a World of Goo-like game demo.

Issues

• #413
• #412
• #411
• #410

2.8.1

Summary

1. Automated export to interactive HTML

• Built-in interactive functions (Manipulate, ManipulatePlot, ManipulateParametricPlot, Animate) are exported automatically.
• “Manual sampling” works like the old “Dynamic HTML” option.
• Fixes #408

2. Manipulate & Animate improvements

• JIT transpiler performance enhanced (though still sensitive to major changes in curves, polygons, or entity counts).
• More examples provided, including support for image manipulation.

3. Improved Shell Cells

• Now use StartProcess, allowing continuous processes without blocking the kernel.
• Processes can be stopped by aborting evaluation as normal.

4. Improved Labels for Graphics

• Fixed label positioning and font rendering bugs including #409
• Added better offset handling for Disk, Circle, and similar elements.
• PlotLabel now supports richer labeling options beyond plain text for both 2D and 3D graphics

6. Bonus – LLM Autocompletion

• Optional AI-assisted code completion available.

7. We removed our offline documentation to cut down the bundle size (~ 50% less)
