Fog Panther v0.8.0 is our largest release yet, built around three themes: professional color and print preparation, high-dynamic-range editing, and automation. Multichannel and spot-color workflows, true CMYK channels, print separations, 32-bit float editing, recordable actions with batch processing, and a new command palette all arrive together - alongside layer groups, two new tools, and broad performance gains.

Organize complex documents with layer groups. Collect related layers into folders, nest groups inside groups, and drag layers in and out to rearrange your stack. Group visibility, opacity, blend modes, masks, and effects all apply to everything inside, so you can manage a whole section of artwork as a single unit. Groups round-trip cleanly through both the native format and PSD.

Four new color modes expand what Fog Panther can produce:

- Multichannel mode with spot channels lets you build separations for specialty inks, varnishes, and custom plates, each with its own ink color and solidity.
- Lab color mode gives you a perceptually uniform working space for color adjustments that keep tones natural.
- Indexed color mode produces compact palette-based images with dithering and palette presets, and adds GIF export.
- Bitmap mode converts images to crisp one-bit black and white using diffusion and pattern-dither methods.

CMYK documents now composite directly in CMYK, so the Channels panel shows true ink plates rather than approximations. A new Print dialog can output color separations, one plate per ink, ready for prepress. A Total Ink Coverage warning flags areas where combined ink exceeds your press limit, and a Halftone Channels filter previews screened output per plate.

Export print-ready PDF/X-1a and PDF/X-4 files, with spot channels preserved as named separations in PDF/X-4. Combined with soft-proofing, gamut warning, and total-ink warning, the prepress pipeline now covers the path from edit to plate inside a single application.

Two new commands under the Image menu bring channel-based compositing to your fingertips. Apply Image blends one document's channels onto another; Calculations combines two channels into a new channel or selection using blend math. Both update in a live preview without freezing the canvas, even on large images.

Fog Panther now edits in 32-bit floating-point precision, preserving the full tonal range of HDR imagery through the entire pipeline — compositing, all 24 blend modes, and a dozen core adjustments run natively in float. You can open and save OpenEXR (.exr) and Radiance HDR (.hdr) files, and PSD import and export now handle 32-bit float documents.

Record a sequence of edits once and replay it on demand. Actions capture your steps as a reusable macro that you can name, manage, and run from the History panel. Batch processing applies an action across a whole folder of images and exports the results automatically — ideal for repetitive production work like resizing, watermarking, or format conversion. Replaying an action on a document is fully undoable.

Press Ctrl+K to open the command palette and jump straight to any tool or command by typing its name. Recently used commands rank first, and commands that are currently unavailable are dimmed so you always know what applies to the current document.

A new Warp tool reshapes layers with a flexible mesh, including a set of ready-made warp presets for common shapes. Drag control points to bend, stretch, and mold image content with smooth interpolation.

A dedicated Hand tool makes navigating large canvases effortless, with flick panning, the option to pan every open window together, and a birds-eye overview for quick repositioning. Touchpad users gain two-finger panning and pinch-to-zoom, and scrollbar indicators fade in during navigation to show your position.

A new Background Remove tool isolates a subject from its background with high-quality edge matting that preserves fine detail like hair.

Large-document PSB files can now be opened and saved. PSD support has grown substantially, with round-tripping of layer groups, layer and vector masks, adjustment layers, editable text, and 16- and 32-bit channels. A redesigned file dialog streamlines opening and saving across every supported format.

Fog Panther is now available in six additional languages — German, Spanish, French, Italian, Japanese, and Portuguese — with imaging terminology chosen to match professional industry conventions in each language. You can switch the interface language from Preferences.

Compositing now runs in parallel across CPU cores, and many operations flatten only the region that changed instead of the whole document, so brush strokes, transforms, and selections stay responsive on large canvases. Panning and zooming reuse cached composites for smoother navigation, and image resizing offers multiple resampling algorithms with threaded scaling.

This release includes an extensive round of stability and correctness work: memory-leak fixes across dialogs and file operations, hardened file readers, more reliable undo and redo, and many small interface refinements. Color management is more accurate, and large-image operations that previously blocked the interface now run smoothly.
