[Unreleased]

[1.1.3] - 2026-03-22

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

[1.1.2] - 2026-03-12

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
• Hover events not blocked during mouse-down drag
• backdrop-blur-sm causing poor rendering performance on Windows

[1.1.1] - 2026-03-12

Fixed

• Ensure auto-routed prompts retain correct individual item text
• Add rounded corners to ImageInput image and InlineParameterPanel settings

Other

• Increase ArrayNode top padding to match side padding
• Add top padding and max-width to ArrayNode top fields
• Update ArrayNode layout to match new design language

[1.1.0] - 2026-03-12

Added

• Router, Switch & ConditionalSwitch Nodes - Three new flow-control node types with toggle UI, rule editing, dynamic handles, and dimming integration
• Gemini Veo Video Generation - Veo 3.1 video models with full parameter support and error handling
• Anthropic Claude LLM Provider - Claude models available in LLM node alongside Gemini and OpenAI
• Floating Node Headers - Headers rendered via ViewportPortal with drag-to-move, hover controls, and Browse button
• ControlPanel - Centralized parameter editing panel with node-type routing and Run/Apply buttons
• Full-Bleed Node Layouts - All major nodes converted to edge-to-edge content with overlay controls
• Inline Parameters - Toggle to show model parameters directly on nodes with reactive sync
• Video Autoplay - useVideoAutoplay hook integrated into all 5 video node types
• Inline Variable Highlights - PromptConstructor highlights template variables inline
• Minimap Navigation - Click-to-navigate and scroll-to-zoom on minimap
• Node Dimming System - CSS-based visual dimming for disabled Switch/ConditionalSwitch paths
• Unsaved Changes Warning - Browser warns before closing tab with unsaved workflow
• All Nodes Menu - Floating action bar with All Nodes dropdown and All Models button
• Provider Filter Icons - ModelSearchDialog filters by available providers

Fixed

• Ease curve outputDuration passthrough through parent-child connections
• Canvas hover state suppressed during panning to prevent re-render cascading
• Node click-to-select failures caused by d3-drag dead zone
• Aspect-fit resize after manual resize aligns with React Flow dimension priority
• Settings panel seamless selection ring, background matching, and z-index layering
• ConditionalSwitch stale input, handle alignment, and text routing
• Veo negative prompt connectable as text handle, error handling, image validation
• API headers scoped to active provider, temperature falsy bug fixed
• Image flicker on settings toggle, presets popup dismiss, modal overlay click-through
• Node paste height compounding, group label anchoring, file input backdrop issues
• Handle visibility on full-bleed and OutputNode, clipped handle resolution
• FloatingNodeHeader width tracking, right-alignment, and Windows drag interception
• Smart cascade made type-aware so text inputs don't rescue dimmed image paths
• RouterNode auto-resize, handle colors, and placeholder styling

Changed

• EaseCurveNode, SplitGridNode, Generate3DControls, GenerateVideoControls refactored to full-bleed patterns
• ConditionalSwitch execution logic deduplicated with shared evaluateRule utility
• ModelParameters collapsible toggle removed

Performance

• Selective Zustand subscriptions replace bare useWorkflowStore() calls
• RAF-debounced setHoveredNodeId and BaseNode ResizeObserver
• Edge rendering optimized for large canvases
• FloatingNodeHeader, InlineParameterPanel, ModelParameters wrapped in React.memo
• useShallow for WorkflowCanvas store subscription
• Narrow selectors for ControlPanel and GroupControlsOverlay

Tests

• Removed redundant and brittle component tests (-1,958 lines)
• Updated assertions for full-bleed nodes, floating action bar, and Gemini video

Other

• Added MIT license
• Handle diameter increased from 10px to 14px
• Settings redesigned with pill tabs, segmented controls, and toggles
• Multi-layer box-shadow for smooth settings panel shadow
