v0.5.0

Minor Changes

• a8186b2: Replace center-pin connection strategy with boundary auto-pins (4 per side, 16 total) for more natural edge attachment positions. Add Symbol.dispose support to RoutingSession for TC39 explicit resource management. init() now warns when called again with a different wasmPath. RoutingSession.addEdge() now validates port pin classes and rejects self-loop edges. writeRoutesToGraph throws on missing owner node instead of silently skipping. getWasmPath() provides descriptive errors when libavoid-js is missing.

Patch Changes

• a8186b2: Fix inferSide to handle zero-length edge segments (identical source and target points) by defaulting to east/west instead of falling through ambiguous comparison logic.
• a8186b2: Fix WASM memory leaks: wrap extractRoutes and createLibavoidSession in try/finally to ensure all Emscripten objects (displayRoute, Point, Rectangle, ConnEnd) are freed on error. Replace freeWasm(obj: any) with freeWasm(obj: unknown) using runtime type narrowing.
• a8186b2: Improve parser validation: detect duplicate node, edge, and port IDs; reject nodes with zero or negative dimensions. Support explicit port.side and elk.port.side properties on ports (case-insensitive), falling back to positional inference when not set.

v0.4.0

Minor Changes

• 5e5c5c1: Support hierarchical graphs with container/group nodes. Container nodes (nodes with children) are no longer registered as hard obstacles, allowing edges to route through group boundaries to reach child nodes inside. Container nodes that are direct edge endpoints still get a ShapeRef so connectors can attach to them.

v0.3.0

Minor Changes

• 6310054: Move getWasmPath() from the main entry to a Node-only subpath export (@mr_mint/elkjs-libavoid/node). This prevents bundlers from statically analyzing node:module and createRequire in browser builds. Also fix getWasmPath() to resolve "libavoid-js" (an exported subpath) instead of "libavoid-js/dist/libavoid.wasm" (unexported), which broke in ESM strict mode and Turbopack.
• b884fa9: Remove routeEdgesFlat(), RouteNode, RouteEdge, OutputFormat, and outputFormat option. Output format is now always auto-detected from the edge format. Use routeEdges() with a graph directly instead of routeEdgesFlat().
• b884fa9: Split LibavoidRoutingOptions into LibavoidRouterOptions (router config) and LibavoidRoutingOptions (adds edgeIds/selfLoopHandling). createRoutingSession() now accepts the narrower LibavoidRouterOptions.

v0.2.0

Minor Changes

• 4bb5ca3: Add sourceSide and targetSide (north/south/east/west) to RouteResult for connection direction metadata
• 4bb5ca3: Add edgeIds option to route only a subset of edges while still using all nodes as obstacles
• 4bb5ca3: Add routeEdgesFlat() convenience API that accepts plain arrays of nodes and edges without requiring a full ELK graph structure
• 4bb5ca3: Add createRoutingSession() for long-lived incremental routing with moveNode(), addEdge(), removeEdge(), and processTransaction()
• 4bb5ca3: routeEdges() now returns a Map<string, RouteResult> without mutating the input graph. Use routeEdgesInPlace() for the previous in-place mutation behavior.
• 4bb5ca3: Add outputFormat option to routeEdgesInPlace(): "auto" (default) matches input format, "simple" forces sourcePoint/targetPoint/bendPoints, "extended" forces sections
• 4bb5ca3: Add selfLoopHandling option: "skip" (default) omits self-loops, "fallback" generates synthetic loop routes
• 4bb5ca3: Export getWasmPath() helper for resolving the libavoid WASM file path, useful for bundler copy plugins and framework configs

Patch Changes

• 4bb5ca3: Fix WASM init race condition using promise guard and add helpful error messages for browser environments missing a wasmPath
• 4bb5ca3: Allow root node to omit width/height (defaults to 0) since the root is never registered as an obstacle
