GIMP 3.3.2 brings key updates including a new project file format (replacing XCF with zipped XML for efficiency), Spectral Blending in My Paint Brush Tool by Cassidie Grogan, and non-destructive editing enhancements by Alx Sa. PSD support improvements by Frank Teklote and Jacob Boerema enable better compatibility with modern files. Native file chooser dialogs now align with platform-specific interfaces. UI updates include SVG icons by Denis Rangelov and performance fixes by woot000. These changes aim to modernize workflows while maintaining backward compatibility.

The new project file format focuses on scalability for complex projects like animations in GIMP 3.6. XCF remains supported but will phase out for new features. This shift to zipped XML enables faster saves and auto-saving. Cassidie Grogan’s Spectral Blending mimics physical pigment mixing, adding realism to digital art. Michael Natterer improved brush previews to full size.

Non-destructive editing now applies filters to layer masks and gradients. PSD import supports editable text layers and modern styles via Descriptor format. Native file choosers on Windows/mac OS/KDE replace GTK dialogs. Performance fixes address rotation and zooming issues.

UI/UX improvements include 78 SVG cursors and redesigned filter popovers. Contributors like Denis Rangelov and woot000 drove these changes. GIMP 3.4 will expand on these updates, prioritizing stability before full release.
