# Changelog

## Unreleased

### Breaking changes

- **Core SDK:** Import scene graph types, geometry, coordinate, matrix, snapping, undo, and path helpers from `@open-pencil/scene-graph`; import `.pen` parsing from `@open-pencil/pen`; and import synchronous Kiwi decompression from `@open-pencil/kiwi` instead of the `@open-pencil/core` compatibility barrel.
- **Vue SDK:** Replace the removed color-picker model helpers with `useColorModel()`; replace the deprecated `FillPickerRoot` and `useFillPicker()` APIs with `FillRoot`, `FillSwatch`, `useFill()`, and a consumer-owned popover; rename `FontPickerUi` to `FontPickerUI`; and remove the exported `testId` prop helper types in favor of semantic component anatomy.

### Added

- Export selections, pages, and documents as editable PowerPoint (`.pptx`) files from the File menu, CLI, and SDK. Text, rectangles, ellipses, and lines remain editable; visually complex layers are embedded as images.
- Import HTML, CSS, Tailwind, and JSX as editable documents from the app, CLI, and SDK, and export standalone browser-ready HTML with compiled CSS and optional external assets.
- Drag image files into the desktop app and paste Figma layers with their remote image fills.
- Import dropped SVG files as editable vector layers, preserving compatible multi-color fills and transparent paints. (#386, #392, #394, #446)
- Convert image layers into editable vectors with Recraft or fal.ai from the canvas context menu. (#322)
- Browse document components as thumbnails or a list in the Assets panel, group them by page, and drag instances directly onto the canvas. (#424)
- Create centered frames from Figma-style device and asset presets, or resize selected frames to a preset while preserving their names. (#418)
- Manage pages by renaming, deleting, and dragging to reorder them in the Pages panel.

- Create and edit layout grids for frames and components, including columns, rows, counts, gutters, margins, visibility, and grid size.
- Inspect and edit constraints, stroke caps and joins, corner smoothing, shared styles, component properties, blend modes, masks, advanced typography, text resizing, and per-node export settings from the Design panel.
- Edit solid fill colors by entering hex values directly in the Design panel.
- Use Figma-style number-key opacity shortcuts: `1`–`9` set 10%–90%, `0` sets 100%, and two-digit sequences set exact values.
- Access more common design actions from the browser and desktop menus, including visibility, locking, masks, flipping, components, z-order, distribution, selection, rulers, multiplayer cursors, and Settings.
- Find overlapping layers and overflowing children from the CLI, AI tools, and MCP.

- Test OpenAI-compatible provider connections from AI settings with clearer setup errors.
- Configure separate Design, Review, Fast, and Vision models, providers, endpoints, and credentials from AI settings.
- Manage AI, agent, media, and storage credentials from unified Settings, using the system credential store on desktop and encrypted browser storage by default, with a session-only browser option.
- Connect an S3-compatible storage workspace with local-first saves and background synchronization.
- Add Japanese localization and improve menu translations across the existing supported languages. (#367)
- Author richer Design JSX with components, instances, variables, gradients, structured fills, shadows, blur effects, masks, and inline SVG vectors.
- Build custom property panels with new Vue SDK number fields, bindable values, property sections, responsive grids, segmented controls, property lists, color models, fill controls, and gradient primitives.
- Use `useColorModel()` in the Vue SDK for extensible color formats and shared RGB, HSL, HSB, and OkHCL channel behavior.
- Add dedicated SceneGraph, Pen, Kiwi, Fig, and DOM/CSS packages with documented public entry points for building on OpenPencil.

### Changed

- Redesign the editor chrome and Design panel with denser, better-aligned controls, clearer selection and section states, improved menus and overlays, consistent light/dark theming, and better keyboard and screen-reader support.
- Choose Freeform, vertical, horizontal, or grid flow directly from the contextual Layout section, with sizing controls grouped alongside it.
- Choose Auto width, Auto height, or Fixed size directly from the Layout section for text layers.
- Scale the Layers panel to documents with thousands of nodes through virtualized rows, faster incremental updates, stable expansion, range selection, and scroll-to-selection.
- Open and save large `.fig` documents substantially faster while preserving original metadata and user edits, and switch between large pages with fewer Layers panel stalls. (#420)
- Resolve fonts before text appears, with language-aware CJK and Arabic fallbacks, character-specific remote subsets, and more reliable rendering as fonts load.

- Let AI and MCP tools create arbitrary vectors from SVG path data, validating input without leaving blank layers behind. (#440)
- Improve AI design accuracy by exposing every supported shape, including visible stroke colors and weights in visual descriptions, and accepting supported inline SVG attributes without false warnings. (#445, #447, #448)
- Restore Anthropic AI connections in the web app instead of failing with a browser endpoint error. (#438)
- Reconnect live CLI and automation sessions automatically after an unexpected bridge disconnection.
- Keep MCP file access inside its configured root when paths contain symlinks, and strengthen local authentication token checks. (#338)
- Start globally installed ACP agents correctly on Windows instead of reporting them as unavailable. (#361)

### Security

- Update the collaboration WebSocket dependency to address a protocol-length advisory.

## 0.13.2 — 2026-05-30

### Changed

- Update the Homebrew install command to use the published `openpencil` cask.

### Fixes

- Fix the published MCP package so global installs include the `openpencil-mcp` and `openpencil-mcp-http` launchers required by desktop app integrations.

## 0.13.1 — 2026-05-29

### Fixes

- Fix the npm package contents for the CLI so Bun installs include the built `openpencil` binary and runtime bundle.

## 0.13.0 — 2026-05-29

### Fixes

- Fix the published CLI package so Bun global installs run the built `openpencil` binary instead of raw TypeScript sources.

- Greatly improve importing Figma `.fig` files with complex component systems: badges, avatars, icons, links, input fields, lists, date pickers, nested instances, component swaps, and variant properties now open much closer to their original Figma appearance.
- Fix missing or white content in imported `.fig` files caused by unresolved Figma variable bindings, including image/avatar badges, icon colors, text colors, and variable-backed component overrides.
- Preserve more Figma document details when opening and saving `.fig` files, including internal component pages, component ordering, page metadata, canvas backgrounds, text layout, glyph rendering, vector geometry, effects, shadows, and instance overrides.
- Keep user edits after opening an imported `.fig` file: changing size, position, fills, text, or layout now wins over preserved Figma round-trip data when the document is saved again.
- Fix `.fig` exports so files reopened in Figma or OpenPencil keep their pages, components, instances, text wrapping, icons, avatars, and preview thumbnail intact.
- Fix live canvas updates during move/resize/edit previews so visible scene changes repaint immediately.
- Fix accidental duplicate creation when Alt-clicking without dragging.
- Fix MCP startup in the browser.
- Fix CanvasKit loading outside the browser when project paths contain spaces.
- Render imported Figma layer and fill blend modes such as multiply, screen, overlay, difference, hue, saturation, color, and luminosity.
- Render common imported Figma mask stacks so visible layers above alpha, vector, or luminance masks are clipped by the mask shape, including consecutive mask layers.
- Render Figma-style smoothed rectangle corners, including independent corner radii, and effect blend modes from imported Figma files.
- Improve imported tiled image fills by applying Figma image transforms when repeating image patterns.
- Keep imported Figma boolean operations editable as boolean-operation nodes instead of flattening them to vectors.
- Apply imported variable font axes from Figma `fontVariations` when rendering text.
- Render more imported Figma visual metadata, including text decoration styles, leading trim, pattern fills, layout grids, page guides, and deterministic fallbacks for raw noise effects.

### Performance

- Open large `.fig` files faster by deferring work for pages you have not viewed yet while still preparing all needed content before export.
- Improve canvas responsiveness during zooming, panning, dragging, and editing by reusing cached scene backing where safe.
- Speed up `.fig` export for documents with many preserved Figma paint and variable payloads.

## 0.12.2 — 2026-05-19

### Added

- Allow OpenRouter users to enter any model ID from provider settings with cached autocomplete suggestions for tool-capable models, while keeping the curated dropdown as the default when no custom model is set.

### Changed

- Use localized app tooltips instead of native browser titles across editor controls, panels, and menus.
- Update Claude Code MCP setup documentation and the docs landing screenshot.
- Ignore non-source Markdown files in the app dev watcher so documentation edits do not reload the running editor.

### Fixes

- Route Claude Code stdio MCP requests through the live OpenPencil app connection, including immediate disconnected errors when no document is connected.
- Keep MCP disconnected guidance focused on starting OpenPencil and opening a document.
- Improve agent-rendered JSX compatibility with Figma-style text, alignment, and rotation aliases; strip HTML comments; and report unsupported props from render tools.
- Load exact text font styles after MCP and AI tool mutations so newly created bold/weighted text renders immediately.
- Include text style fields in MCP `get_node` output so agents can verify generated text accurately.
- Keep provider settings tooltip/popover composition working in WebKit.

## 0.12.1 — 2026-05-19

### Fixes

- Fix `.fig` round-trips for OpenPencil component sets and variable bindings, and recompute imported layouts after opening documents.
- Report desktop/MCP package version mismatches explicitly and include package-manager-aware install guidance from the MCP server.
- Support scoped MCP `save_file({ path })` workflows while keeping file saving in the desktop app.
- Use native Tauri path handling for save parent directories so Unicode and Windows paths are handled correctly.
- Fix the web font picker so Google Fonts remain available in Safari, local font access is requested on first open when supported, font sources are labeled, and Google font previews load lazily for visible rows.
- Fix background blur rendering so it blurs the backdrop behind a layer instead of applying a no-op content filter, and keep effect parameter controls visible in the properties panel.

## 0.12.0 — 2026-05-18

### Added

- Assets panel — browse, search, and insert document components directly from the left sidebar.
- Component variants — switch instance variants from the right inspector; default variant respects property definitions.
- Figma library metadata — component keys, source libraries, version IDs, descriptions, and docs links are preserved on import/export.
- Desktop file associations — double-click `.fig` or `.pen` files in Finder/Explorer to open them in OpenPencil.
- Auto-update — startup update checks and a Check for Updates menu item on desktop.
- Light theme with theme-aware canvas rulers.
- PDF export — available in the export panel, CLI (`--format pdf`), and MCP.
- SVG import tool for automation workflows.
- DeepSeek AI provider.
- Variable modes — create, rename, duplicate, delete, and set defaults per collection.
- Variable binding controls for fills, strokes, sizing, min/max, and typography fields.
- Auto-layout inspector controls for min/max dimensions, auto gap, wrap gap, and two-axis padding.
- Stroke dash/gap controls.

- Editor commands for frame selection, paste to replace, Boolean operations, flatten, outline text, and outline stroke.
- Boolean operations panel control and canvas context-menu entries for flattening and outlining supported selections.

### Changed

- Smaller domain modules across core, app, Vue SDK, CLI, MCP, docs, and desktop with enforced package boundaries.
- Separate scene and overlay canvas layers — rulers, labels, and selections no longer cause scene redraws.
- Shared menu schema between browser and native Tauri menus.
- Editor command metadata now drives shortcut display across browser menus, native menus, tooltips, and context menus.
- Text-to-vector conversion now uses shared loaded-font outline geometry across Boolean, flatten, and outline commands.

### Fixes

- Fix `.fig` export of component variant properties and text stretch alignment so designs round-trip correctly through Figma.
- Fix CJK and Arabic text rendering — fallback fonts now load before the first paint instead of showing blank text.
- Fix large `.fig` files freezing on open — parsing runs in a worker, and the viewport fits to content after loading.
- Improve Figma import fidelity — variable aliases, nested instances, avatar swaps, badge internals, and input text alignment are preserved.
- Improve Figma export fidelity — flipped vectors, stroke geometry, visual overflow, and stroked-shape drop shadows are preserved.
- Fix variant switching so instances update their contents, not just the component reference.
- Fix text editing inside components and instances on double-click.
- Fix paste into selected containers and entered frames.

- Fix section drawing and color input forwarding in the property panel.
- Fix asset insertion coordinates inside entered containers.
- Fix MCP stdio handshake and eval return values.
- Fix `@open-pencil/vue` npm imports referencing an unexported core subpath.
- Fix Figma clipboard text compatibility — pasted OpenPencil text keeps editable fixed bounds, line wrapping, baselines, glyph offsets, and Figma edit-mode layout.
- Fix local font matching so requested upright and weighted faces do not fall back to italic or regular faces.
- Fix CanvasKit paragraph rendering to preserve requested text weights and slants.
- Fix nested text editing interactions — drill double-click enters nested text edit mode, and clicking another text node switches edit targets while editing.
- Fix auto-height text edit commits so text bounds and undo state stay in sync.
- Fix Boolean, flatten, and outline operations to reject unsupported image/complex-script sources safely instead of silently dropping geometry.
- Fix outline stroke enablement for stroked descendants inside groups and containers.

### Performance

- Event-driven canvas rendering — scene and overlay layers only repaint when their inputs change, replacing continuous polling.
- Shared RAF scheduler coalesces scene and overlay frames into a single animation frame per editor.
- Font-family fallback arrays and downloaded remote fonts are cached to avoid repeated work.
- WebGL draw-call instrumentation only runs while the profiler is active.
- Instance override resolution is cached and `.fig` pages load lazily for large files.
- Live drag/resize uses repaint-only previews to skip layout during interaction.

- Vue SDK now exposes reusable color-picker model helpers and solid fill/stroke commit helpers for custom editor shells
- Update built-in Z.ai and MiniMax model lists — Z.ai now uses the Anthropic-compatible endpoint for GLM coding models, adds GLM-5.1, and MiniMax adds M2.7 / M2.7-highspeed
- Arabic and RTL support across text rendering, editing, layout, export, and AI tooling — text nodes support `Auto`/`LTR`/`RTL`, auto-layout frames support `Auto`/`LTR`/`RTL` flow, and JSX/AI prompts/tools can now generate and edit both explicitly

### Fixes

- Fix shortcuts, now work on non-English keyboard layouts.
- Fix imported `.fig` file open and page-switch regressions — loaded documents now keep graph/store state in sync, remap imported canvas/page children correctly, and recompute imported auto-layout descendants when switching pages
- Fix first canvas render happening before fonts load — wait for fonts before the initial draw to avoid Safari and text measurement glitches
- Preserve `fig-kiwi` version on `.fig` roundtrip — imports keep the original header version instead of rewriting everything to a hardcoded value; new files default to version 101
- Normalize auto-layout text export for Figma — text children inside auto-layout frames now serialize with `NONE` auto-resize to match Figma behavior and avoid overflow on reimport

- Improve CJK font fallback coverage — load multiple Google Fonts for broader Han/Japanese/Korean text support
- Normalize more visible UI strings for localized app chrome — menus, panels, variables dialog, code panel, chat setup, and editor controls now respect the selected locale instead of falling back to English in common flows
- Fix imported text rendering in browser and headless export — preserve stored bounds until fonts are ready, restore missing font-loaded guards, use natural width for `WIDTH_AND_HEIGHT` text, and clip text to node bounds
- Fix browser/headless rendering mismatch for imported toolbar/instance content by correcting runtime imported layout recomputation instead of diverging browser rendering behavior
- Fix `set_layout` tool not defaulting to HUG sizing when enabling auto-layout — frames now shrink/grow to fit children instead of keeping fixed dimensions
- Normalize font family names on `.fig` export — strip optical size suffixes (e.g. "DM Sans 9pt" → "DM Sans") so Figma recognizes the font
- TEXT nodes now default to a solid black fill — previously exported with no fill, making text invisible when opened in Figma
- Fix save crash when COLOR variable is missing alpha channel
- Fix console error spam on deployed web app from automation WebSocket reconnect loop
- Fix headless CLI font fallback — bundled Inter font now ships with `@open-pencil/core` and loads without a web server

- Locked containers block double-click enter
- Marquee selection skips locked and hidden nodes
- COMPONENT/INSTANCE containers are now enterable via double-click
- Replaced the alignment and reflection icons with the correct ones

## 0.10.0 — 2026-03-15

### Performance

- Offload .fig parsing (unzip + Kiwi decode) to a Web Worker — main thread stays responsive during file open
- Offload .fig compression to a Web Worker during save (was blocking 450ms+)
- Add instance index (`componentId → Set<nodeId>`) — `getInstances()` is O(1) instead of scanning all nodes
- Defer graph event subscription until after layout computation during file open — eliminates redundant `syncInstances` calls
- Cache label collection (sections/components) per scene mutation instead of walking the full tree every frame
- Blocking font loading — fonts load before first render to ensure correct glyphs

- Batched AI tools — `calc` accepts arrays of expressions, `stock_photo` fetches all images in parallel, `batch_update` applies multiple property changes in one call, `describe` accepts `ids` array for multi-node inspection
- AI visual feedback — blue pulsing border on nodes being modified, green flash on completion
- Auto-depth `describe` — adapts inspection depth to subtree size (small block → deeper, large page → shallower)
- `set_fill` gradient support — linear gradients with `color_end` and `gradient` direction params
- `render` tool `replace_id` — atomically swap skeleton placeholders with real content
- MCP `export_image_file` tool for headless PNG rendering

## 0.9.0 — 2026-03-09

### Features

- XPath query command — `open-pencil query design.fig "//FRAME[@width < 300]"` to find nodes by type, attributes, and tree structure using XPath selectors
- CSS Grid layout mode — select a frame, click the grid icon in the auto layout toolbar to switch from flex to grid. Configure column/row tracks (fr, fixed px, auto), column and row gaps, and per-side padding. Powered by a [Yoga fork](https://github.com/open-pencil/yoga/tree/grid) with cherry-picked CSS Grid PRs from upstream
- JSX and Tailwind CSS export for grid layouts — `grid grid-cols-N`, `gap-x-*`/`gap-y-*`, child `col-start-*`/`row-start-*`/`col-span-*`/`row-span-*`
- Multi-provider AI support — connect to Anthropic, OpenAI, Google AI, or any OpenAI-compatible endpoint directly, in addition to OpenRouter. Per-provider API key storage, provider settings popover, automatic migration from single OpenRouter key
- Anthropic-compatible provider for custom API endpoints
- New AI tools: `get_jsx` (JSX roundtrip view), `diff_jsx` (structural diff), `describe` (semantic role, visual style, layout, design issues)
- AI visual verification — `export_image` returns image content to the model for vision-based review
- API type toggle (Completions/Responses) for OpenAI-compatible providers
- Figma zoom shortcuts — ⌘0 (100%), ⌘1 (zoom to fit), ⌘2 (zoom to selection), ⇧1/⇧2 alternatives
- XPath query tool — `query_nodes` for AI/MCP with attribute selectors, tree traversal, and type filtering

### Fixes

- Serialize variables, collections, and bindings to `.fig` files — previously lost on save (#65)
- Text nodes created via MCP now render in Figma — emit `derivedTextData` with font metadata and layout size (#64)
- Double-click on layer tree no longer toggles expand/collapse — use the chevron instead
- Page rename input matches layer rename styling
- Fix `w="fill"`/`h="fill"` in JSX renderer — now direction-aware based on parent flex axis
- Fix text auto-resize defaulting to fixed 100×100 — text without explicit width uses `WIDTH_AND_HEIGHT`
- Fix `clipsContent` not propagated to Yoga — frames with clip enabled now set `Overflow.Hidden`
- Fix `COUNTER_ALIGN_MAP` mapping stretch to `MIN` instead of `STRETCH`
- Fix JSX export omitting x/y for absolute-positioned children
- Fix JSX export ignoring `textAutoResize` for text sizing

- Fix text typography lost on Figma clipboard import — preserve fontFamily, fontWeight, fontSize, lineHeight
- Fix `copyFill` missing `gradientTransform` and `imageTransform` — gradient fills now round-trip correctly

### Performance

- Event-driven rendering and component sync — `SceneGraph` emits typed events on mutations; `requestRender()` calls reduced from 94 to 22, component instance sync uses microtask batching with deduplication
- Replace `structuredClone` with typed copy helpers for fills, strokes, effects, and style runs (~24× faster in hot paths)
- Filter .fig unzip to only decompress canvas and image entries, skipping metadata cruft

### Improvements

- Padding on a frame auto-enables vertical auto-layout
- AI tools run `computeAllLayouts` after execution — layout updates immediately
- Enhanced AI system prompt with full JSX prop reference and verification workflow
- Chat panel preserves messages when toggling UI visibility
- SceneGraph event bus (nanoevents) — `node:created`, `node:updated`, `node:deleted`, `node:reparented`, `node:reordered` events replace monkey-patching in collab sync and manual render invalidation
- Replace esbuild-wasm (14 MB) with sucrase (201 KB) for JSX transform — `buildComponent()` and `renderJSX()` now synchronous and browser-compatible
- `useMagicKeys` keyboard shortcut system — replaces tinykeys with VueUse built-in, cross-platform Meta/Control handling, modifier exclusion for combo conflicts
- Dev-only debug toolbar for copying chat logs
- Auto-layout icons in layer tree — vertical (rows), horizontal (columns), and grid icons for auto-layout frames; components keep their purple diamond
- Frame titles on canvas are now draggable — clicking a selected top-level frame's name label starts a drag
- Compact layout controls — icon-based gap (↔/↕) and padding (T/R/B/L) inputs instead of text labels
- Auto-detect horizontal vs vertical direction when wrapping in auto layout (Shift+A)
- Fix alignment grid for vertical layouts — visual positions now match spatial axes
- Fix grid switch from HUG-sized frames — frame expands to fit children
- Remove unwanted white fill when wrapping in auto layout

- Tailwind CSS v4 JSX export — export selections as HTML with Tailwind utility classes (`<div className="flex gap-4 p-3">`) from the Code panel, CLI (`bun open-pencil export --format jsx --style tailwind`), or programmatically via `sceneNodeToJSX(id, graph, 'tailwind')`. Supports layout, sizing, colors, border radius, opacity, rotation, overflow, shadows, blur, and typography. Uses v4 spacing semantics (px/4 multiplier) with automatic fallback to arbitrary values.
- Code panel format toggle — switch between OpenPencil (custom components) and Tailwind (HTML + utility classes) output
- Homebrew tap — `brew install open-pencil/tap/open-pencil` for macOS (arm64 + x64), auto-updated on each release

- VitePress docs site — user guide, reference, architecture, and development docs at openpencil.dev with 6 locales (en, de, fr, es, it, pl), SEO (OG tags, hreflang, JSON-LD, sitemap), and dark theme

### Improvements

- Refactor mobile drawer tabs, layout sizing dropdowns, and inline rename to use Reka UI primitives
- Add shared UI style helpers with tailwind-variants for menus, selects, buttons, and surfaces
- Unified tool definitions — define once in `packages/core/src/tools/`, automatically available in AI chat, CLI, and MCP

### Internal

- Add `motion-v` for declarative animations — used in mobile drawer (spring-animated height with pan gestures) and toolbar (layout-animated category switching with directional slide transitions)
- Mobile drawer: replace `useSwipe` + manual rAF animation with `motion.div` `:animate` + `@pan`/`@panEnd`; always-on tab state (no more null `activeRibbonTab`); content stays rendered when closed
- Mobile toolbar: replace manual `scrollWidth` measuring + inline CSS transitions with `motion.div layout` + `AnimatePresence` directional slide variants

- Renderer profiler with in-canvas HUD overlay, GPU timing, and phase instrumentation

### Improvements

- Replace custom color picker with Reka UI Color components (ColorArea, ColorSlider, ColorField) — adds keyboard navigation and accessibility to the color area, hue, and alpha controls

### Fixes

- CJK text rendering — load a system CJK font (PingFang SC, Microsoft YaHei, Noto Sans CJK) as fallback; falls back to Noto Sans SC from Google Fonts when no system font is available (#48)
- Font registration errors no longer cache invalid font data — `loadFont` only caches after successful CanvasKit registration
- Fix `render` tool failing on Windows + Bun with "Cannot find module" error (#43)
- Fix hover highlighting nodes from internal component pages — scope hit-test to current page
- Fix hit-testing on transparent frames and groups — empty containers without fills or strokes are now click-through, clipping parents reject hits outside their bounds, matching Figma behavior
- Fix instance overrides on .fig import and clipboard paste — resolve guidPaths by overrideKey, handle component swaps (`overriddenSymbolID`), propagate through nested clone chains. Import and paste now share a single override engine.
- Apply Figma component property assignments on import — boolean visibility toggles and instance swaps via `componentPropRefs`/`componentPropAssignments`
- Apply `derivedSymbolData` sizes on import — containers now shrink correctly when component properties hide children
- Fix override resolution for nested instance targets — check the current node before searching descendants
- Fix component property assignments for nested instances — resolve scoped `componentPropAssignments` inside `symbolOverrides` via guidPath, handle `guidValue` for instance swaps, reorder phases so transitive sync doesn't clobber visibility
- Pixel-perfect vector rendering using pre-computed `fillGeometry`/`strokeGeometry` blobs from .fig files — eliminates white gaps between adjacent stroked shapes
- Stroke outlines on clipboard paste — convert vectorNetwork paths to filled outlines via CanvasKit when geometry blobs are unavailable
- Apply `derivedSymbolData` transforms and geometry during import — instance children render at correct scale and position
- Fix internal pages becoming visible after .fig round-trip — preserve `internalOnly` flag on export
- Scope layout recomputation to current page for paste/undo/font-load (major speedup on large multi-page files)
- Show loading overlay until all document fonts are loaded (no more partially rendered text)
- Load fonts when switching pages (previously only loaded for the first page)
- Always show visibility toggle on fill, stroke, and effect rows (matches Figma)
- Fix renderer crash on double destroy when closing files quickly
- Fix .fig page ordering — use deterministic byte comparison for fractional index positions
- Fix text truncation using `textTruncation` field instead of `textAutoResize`
- Fix horizontal scrollbar on design and pages panels
- Style scrollbars for Tauri (thin dark overlay instead of default OS chrome)
- Enable file watcher in Tauri — `watch` feature was missing from `tauri-plugin-fs`

- Fix pasted instances having no children — populate from component via symbolData when both are in clipboard
- Detect component sets on import — promote FRAME nodes with VARIANT componentPropDefs to COMPONENT_SET
- Skip internal canvas on paste — components on Figma's hidden internal page populate instances but are not pasted as visible nodes
- Apply instance overrides on paste — text content, fills, visibility, layoutGrow, and textAutoResize from symbolOverrides
- Fix auto-layout child ordering — sort by geometric position instead of z-order position strings
- Load fonts on paste and .fig import — collect font families from text nodes and load into CanvasKit
- Text measurement in auto-layout — use CanvasKit paragraph metrics for WIDTH_AND_HEIGHT text nodes
- Recompute layouts after font loading completes
- Fix PERCENT line height conversion — was stored as raw value instead of pixels
- Fix InvalidCharacterError when copying nodes with non-ASCII text
- Load all font weight/style variants needed by pasted text nodes
- Fix font loading not registering in core cache
- Fix halfLeading applied to text measurement — enable only for rendering
- Clear hover on zoom/pinch to keep scene picture cache valid
- Fix flip buttons using rotation math instead of actual mirroring
- Fix flip transform encoding — scale first matrix column only (was incorrectly producing 180° rotation)
- Decode flip state from .fig transform matrix on import

- Fix active tab text invisible against same-color background
- Fix clipboard "Outside int range" error — `pasteID` used unsigned int exceeding Kiwi's signed 32-bit field
- Error toasts are now sticky (don't auto-dismiss), with selectable text, copy button, and close button
- Truncate long node names in export button

### Performance

- Per-node SkPicture cache for effect rendering — unchanged shadow/blur nodes replay from cache on scene redraws
- Drop shadows use `MaskFilter` direct draw instead of `saveLayer` offscreen buffers
- Cached `ImageFilter`, `MaskFilter`, reusable effect paint — zero per-frame WASM allocations for effects
- Reuse GL context on panel resize — swap surface without recreating renderer, preserving all caches
- Per-frame absolute position cache — avoids repeated parent-chain walks during rendering
- Optimize zoom/pan smoothness with `shallowReactive`, `useRafFn`, and input coalescing

### Build

- Auto-populate GitHub Release notes from CHANGELOG.md via `ffurrer2/extract-release-notes@v2`

## [0.4.2] (2026-03-02)

### Fixes

- Fix Figma clipboard paste: skip non-visual node types (variables, widgets, stickies, connectors)
- Fix text not rendering after paste — `letterSpacing` from Figma is a `{value, units}` object, was passed as-is → `NaN` broke CanvasKit paragraph layout
- Fix undo/redo for Figma paste — no undo entry was recorded; redo duplicated `childIds`
- Center pasted Figma content in viewport instead of using original coordinates
- Compute auto-layouts after clipboard paste (same as .fig import and demo creation)

### Improvements

- Import additional properties from Figma clipboard: `layoutAlignSelf`, `clipsContent`, `fontWeight`, `italic`, `letterSpacing`, `lineHeight`
