## Summary
The GIMP team has released a development update detailing upcoming features for the GIMP 3.3.2 and 3.4 releases. Key improvements include a new project file format to replace the aging XCF binary format, non-destructive editing for filters and gradients, and significantly improved PSD compatibility. The update also highlights MyPaint brush enhancements and the implementation of native file chooser dialogs across different platforms.

## Technical advancements in GIMP
- **New Project Format**: Moving from binary XCF to a "zipped XML" structure to enable faster partial updates and auto-saving.
- **Non-Destructive Editing**: Filters can now be applied to layer masks non-destructively, and the Gradient Tool functions as an editable filter in the stack.
- **PSD Compatibility**: Implementation of PSD Descriptor support allows for editable text layers, adjustment layers, and vector-based solid color shapes.
- **MyPaint Brush**: Addition of Spectral Blending to simulate physical pigment mixing and high-resolution SVG cursor icons.
- **UI/UX**: Porting to native GTK3 file choosers for better integration with Windows, macOS, and KDE.

## Why it matters
The shift to a modern project format and improved PSD handling significantly lowers the barrier for professional workflows and cross-platform collaboration.
