∙ Fixed a minor bug that resulted in a blank palette appearing in the palette library. 1.7.1 Apr 28 Mandelbrot Metal v1.7 is here — and this release goes straight to the core of what matters: the render pipeline.

This update introduces targeted performance improvements across both GPU and CPU paths, reducing redundant work while preserving full visual fidelity.

• Faster per-pixel execution in the Metal shader
• Smarter deep-render updates with fewer redundant redraws
• No compromises — same precision, same iteration behavior, same image quality

You’ll feel it most during deep exploration and progressive refinement — everything just flows more cleanly. 1.7 Apr 25 ● New
∙ Added a new 768-step ultra-wide palette: “Bridge [UW].” This brings the total number of built-in palettes to 155, including 54 ultra-wides. 1.6.10 Apr 19 ■ Improvements
∙ Improved the import gradient feature to use the improved code already used in the advanced command line interface tool. Now you can import gradients from your photos, which are more precise and accurate, reliably from within the app. See the User Guide for more details.
