You have to authenticate Codex yourself, and it consumes token from your plan. The prompt will be sent to OpenAI ## 1.0.0-alpha.4 - Build 166 - 2026-09-16 ### Added * VTracer 2 now picks the optimal Gradient Step on first trace ### Fixed * Remove Background stayed on but stopped showing on the canvas after switching tabs. ## 1.0.0-alpha.4 - Build 161 - 2026-09-12 ### Added * 简体中文 for UI display language. ### Added (Gen AI) * Generation on your own sd-server * Inked, an art style for SDXL-Turbo ## 1.0.0-alpha.4 - Build 151 - 2026-09-09 ### Added * An model manager to install/uninstall VTracer 2 engine versions * Factory Reset under Settings > Application. It removes everything VTracer 2 and Gen AI keep on the device ### Fixed * Trial activation issues ## 1.0.0-alpha.4 - Build 143 - 2026-09-08 ### Added (Gen AI) * The FLUX model family, alongside the Stable Diffusion models * Art styles for the FLUX models * Starring a round in the left panel, each round also shows the model * Gradient Step is now determined dynamically, picking the optimal value per artwork ## 1.0.0-alpha.4 - Build 133 - 2026-09-07 ### Added * Gen AI preview. Supports 2 Stable Diffusion model lines, SD Turbo and SDXL Turbo. Requires Vulkan support on Windows. Requires an active VT2 license. * The app now offer VTracer 2 engine update. ### Changed * VTracer 2 composites with Stacked rather than Cutout by default. * An expired VTracer 2 trial no longer locks the images you have already traced. They can still be reopened and exported, and only new tracing needs an active licence. ### Fixed * Retrying VTracer 2 setup after an interrupted install no longer asks for a second device seat for the same machine. * A trace with its background removed now sits on a light checkerboard in dark mode. ## 1.0.0-alpha.4 - Build 116 - 2026-08-29 ### Added * VTracer 2 preview. Trial license can be activated in app. * SVG saving without a dialog. A preferred save folder can be set in Preferences, or the app can keep asking each time. * A source image display preference, choosing smooth or pixelated scaling for the source image. * Selected SVG shapes now show their bounds, and can be dragged around the canvas to inspect what sits beneath them. * A configurable disk cache limit for VTracer 2, defaulting to 2 GB. Lowering it reclaims space immediately. ### Fixed * Pasting an image now works consistently across the app rather than only when the canvas held focus. ## 1.0.0-alpha.3 - Build 59 - 2026-08-14 ### Added * User-managed presets. A preset stores the complete tracing configuration and its source image; presets can be created or updated by name, reordered, deleted, and restored to the shipped defaults. * Side-by-side comparison mode with synchronized, mirrored views of the source image and generated SVG. Switching between overlay and side-by-side comparison preserves the canvas position and zoom. * A new etched-cat sample demonstrating adaptive black-and-white tracing. ### Changed * The canvas comparator and SVG rendering now remain sharp and stable while zooming, panning, dragging the divider, and switching comparison modes. ### Fixed * Trace sessions recover after an engine panic instead of leaving the app stuck with an unavailable session cache. * Large images and repeated image uploads no longer leave the frontend unable to start a new trace. ## 1.0.0-alpha.3 - 2026-08-01 First public preview of the rebuilt VTracer desktop app. ### Added * Native VTracer 1.0 tracing for macOS and Windows, with Linux packaging support. * Cancellable tracing with stage-aware progress. Changing a tracing control aborts obsolete work and immediately starts the new trace. * Session caching that reuses expensive clustering work while tuning compatible curve and color fitting settings. * An interactive source/SVG comparator with a draggable divider, zoom controls, scroll-to-zoom, drag-to-pan, actual-size and fit modes, and a focused full-canvas view. * SVG shape inspection with yellow hover outlines and selectable curve nodes. * Full controls for color, black-and-white, and watershed clustering; stacked and seam-free cutout composition; pixel, polygon, and spline fitting; fixed palettes; adaptive thresholding; and curve simplification. * Open, paste, and drag-and-drop image input, including EXIF orientation normalization for camera images. * A scrollable sample preset strip with image credits. * Native SVG save dialogs and save completion feedback. * System light and dark themes. * In-app update checks, engine release notes, and open-source license information. ### Changed * Tracing runs in the native backend rather than WebAssembly. * The desktop shell serves the frontend and API over an authenticated loopback HTTP session, aligning development and production behavior. ### Fixed * External links open directly in the default browser on macOS and Windows without displaying a command window. * Native context menus are suppressed across production app surfaces.
