Fog Panther v0.6.0 is the largest release to date, delivering dozens of professional features for a complete creative workflow. This release adds a full Pen tool with path operations, a Paths panel, layer effects, fill layers, vector masks, new creative filters, four new tools, SVG import, PSD layer effects round-tripping, and sweeping UI refinements.

------------------------

A full Bezier pen tool with rubber-band preview, dynamic cursors, and accurate anchor insertion. Paths support boolean operations (union, subtract, intersect, exclude) with full undo. A custom shape library lets users store and recall reusable path presets.

The new Paths panel provides a complete path management workflow: create, rename, duplicate, and delete paths; convert paths to selections and selections to paths; fill and stroke paths.

Type on Path places text glyphs along arbitrary Bezier curves using arc-length sampling for even spacing.

------------

Layers can now be clipped by vector paths instead of (or in addition to) raster masks. Vector masks are resolution-independent and produce perfectly sharp edges at any zoom level.

-------------

A full non-destructive layer effects stack:

  - Drop Shadow, Inner Shadow, Outer Glow, Inner Glow
  - Color Overlay, Gradient Overlay, Pattern Overlay, Satin
  - Stroke
  - Bevel & Emboss

Effects are live-previewed and preserved through PSD import/export.

-----------

Three new fill layer types:

  - Solid Color — flat color fill with color picker
  - Gradient — linear, radial, or angular gradient fill
  - Pattern — tiling pattern fill

Fill layers are non-destructive and support masks, opacity, blend modes, and clipping like any other layer.

---------

Healing Brush — Uses Poisson blending to seamlessly repair blemishes by matching texture, lighting, and shading from a sampled source.

Magnetic Lasso — Edge-snapping selection tool that follows contrast boundaries, making it easy to select complex shapes along well-defined edges.

History Brush — Paints from a user-selected history state, with a source indicator in the History panel for visual feedback.

Red Eye — One-click red-eye removal tool.

Liquify — A dedicated dialog for freeform mesh warping with push, bloat, pucker, and twirl modes.

-----------

Creative:
  - Channel Mixer — Remix RGB channel contributions with a monochrome option for fine-tuned black & white conversion
  - Selective Color — Adjust CMYK sliders within specific color ranges (reds, yellows, greens, cyans, blues, magentas, whites, neutrals, blacks)
  - Gradient Map — Maps luminance to a configurable color gradient
  - Smart Sharpen — Richardson-Lucy deconvolution sharpening with shadow/highlight fade controls
  - Reduce Noise — LAB-space bilateral/median pipeline for luminance and color noise reduction

Stylize:
  - Solarize, Find Edges, Emboss, Wind

Pixelate:
  - Mosaic, Crystallize

Distort:
  - Six new distort filters

Channel Mixer, Selective Color, and Gradient Map are also available as non-destructive adjustment layers, bringing the total from 12 to 15 types.

--------------------------

Filters are now organized into categorized submenus:

  Filter
  +-- Blur        (Gaussian, Box, Motion, Radial, Surface)
  +-- Sharpen     (Sharpen, Smart Sharpen)
  +-- Noise       (Add Noise, Reduce Noise)
  +-- Pixelate    (Mosaic, Crystallize)
  +-- Stylize     (Solarize, Find Edges, Emboss, Wind)
  +-- Distort     (6 distort filters)
  +-- High Pass

----------

Vector graphics can now be imported via librsvg, with incremental load progress reporting for large files.

----------------------------

PSD import and export now support the full layer effects stack, reading and writing both legacy lrFX records and modern lfx2 descriptors for broad compatibility.

---------------

  - Tool groups with flyout menus for a compact, organized toolbar
  - Quick Mask button in the toolbar
  - Revised tool keyboard shortcuts for an efficient workflow
  - Scrollable panel tabs with mouse-wheel switching
  - Unified panel toolbar icons for delete and new buttons
  - Color picker colors now saved to preferences
  - Context menu popover fixes

-------------------

- Linux with GTK4 (>= 4.10)
- Available as Flatpak, Snap, .deb, .rpm, and Arch packages
