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

• 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

v1.4.0

Added

• Audio-to-video generation — Video generation nodes now accept audio inputs, enabling audio-driven video workflows with handle rendering, connection validation, model discovery, and drop-menu wiring
• Array batch mode — New batch execution mode that sequentially generates from all items in an array, with shared helper logic across all execution entry points

Fixed

• Undo/redo memory bloat — Eliminated excessive memory usage caused by deep-cloning base64 image blobs in history snapshots; clipboard and snapshot operations now use a string-preserving clone
• Cancellable batch execution — Wired AbortController into regenerateNode so batch runs can be properly cancelled
• Output gallery correctness — Output gallery now reads fresh node data to preserve all batch-generated images
• Array batch behavior — Batch mode is now derived dynamically from the source node rather than being statically configured

v1.3.0

Added

• Video Input node — Upload, preview, and wire video files through workflows with drag-and-drop support, native playback controls, and full-bleed styling matching Image Input nodes
• Undo/Redo — Full undo/redo history with Cmd+Z / Cmd+Shift+Z, intelligently coalescing multi-node deletions into single undo steps

• NB Pro Waitlist — Added waitlist link to the welcome modal

Fixed

• Selected-node execution now properly hydrates audio and video input nodes from upstream connections

v1.2.0

Added

• Workflow Browser — browse, search, and open saved workflows from a new modal (supports nested subdirectories, directory picker, and last-used path memory)
• Media Externalization — videos and audio now save alongside images in the generations/ folder for portable workflows
• Optional Inputs & Skip Propagation — mark input nodes as optional; execution skips downstream nodes when optional inputs are empty
• Group Context Menu — redesigned as a vertical dropdown with color picker, lock toggle, and NBP Input flag

Fixed

• Video/audio save-load roundtrip (3 compounding bugs)
• Lock icon now shown on locked groups
• Error state cleared when navigating generation carousel
• Various a11y, regex, and dialog semantics fixes

Performance

Documentation

• Redesigned README with hero layout, all 23 node types, and updated screenshots

v1.1.3

Fixed

• Clamp expand height to minHeight and resolve text through switch nodes
• Move ImageInputNode handles after visual content to prevent z-order clipping
• Add z-index to handles so they paint above positioned node content
• Move overflow-clip from contentClassName to inner visual wrappers to prevent handle clipping
• Move panel height correction from loadWorkflow into BaseNode render
• Prevent node height accumulation with inline parameters on reload
• Update WelcomeModal test to match bg-black/60 backdrop class
• Resolve prompt variables through router nodes for PromptConstructor
• Use overflow-visible on non-fullBleed nodes to prevent handle clipping

Other

• Replace ArrayNode auto-route icon with Lucide split icon

v1.1.2

Added

• Adaptive image resolution scaling — swaps full-res images for JPEG thumbnails when nodes are small on screen

Fixed

• Router/switch passthrough losing data when multiple types (text + image) flow through the same router to one target
• SplitGrid node Split button permanently disabled — sourceImage now updates reactively when an edge is connected
• Node connection handles clipped at edges — removed paint containment that acted like overflow hidden
• Thumbnail cache key collisions causing wrong images on nodes
• Pending thumbnail map not cleaned up on rejection, causing stale entries
• Pointer-events on node images/content blocking pan and drag interactions
• Hover state updates firing during node drag, causing unnecessary re-renders
