v1.5.0

Added

• Onboarding & setup flow — New first-run setup experience to get users configured and started quickly
• Interactive tutorial — Guided onboarding tutorial that walks first-time users through the workflow editor with mock execution and step-by-step demonstration
• Kie.ai model expansion — Added 7 new image models, Kling 3.0 / 3.0 Motion Control, Wan 2.7 (text-to-video & image-to-video), and Seedance 2.0 / 2.0 Fast video models
• Model fallback/redundancy — Generation nodes now support a fallback model that automatically kicks in if the primary model fails, with a dedicated settings tab for configuring fallback parameters
• Loop edges — Connect a node's output back to an upstream input with magenta-styled loop edges and configurable iteration counts via an edge toolbar
• Client-side polling — Long-running Kie tasks now return immediately and poll for results on the client side, keeping the UI responsive during video/3D generation
• Download buttons — All media-displaying nodes (image, video, audio, 3D) now have download buttons
• Output gallery extraction — New "Extract" button on OutputGalleryNode to batch-create input nodes from gallery items
• Handle labels — Connection handles now show descriptive labels on hover/select/drag for easier wiring

Fixed

• Video handle and edge colors — Unified video handles, labels, and edges to consistent pink styling
• Loop execution reliability — Fixed downstream observer collection during loop iterations, validated loop counts, and handled resume inside loops
• Orphaned edge cleanup — Edges referencing deleted nodes are now filtered out on workflow load
• Audio stitching — Embedded audio is preserved when stitching video segments
• Kie API compatibility — Fixed Seedance 2.0 model ID mapping, schema defaults pre-population, and video/audio upload handling
