+## [1.3.0] - 2026-03-15
+
+### Added
+
+- **Port ordering**: `portOrder` field on `NodeUIExtensions` lets consumers define a custom display order for ports on WorkflowNode, SimpleNode, and SquareNode.
+- **Manual port hiding**: `hiddenPorts` field on `NodeUIExtensions` allows specific ports to be explicitly hidden by ID, complementing the existing "hide unconnected ports" setting.
+- **All-ports display**: SimpleNode and SquareNode now render all ports by default. The previous heuristic that limited display to at most one data port and one trigger port per side has been removed.
+- **Shared port utilities**: `getPortTop` and `isPortVisible` extracted as pure, tested utilities in `portUtils.ts`, eliminating duplicated positioning and visibility logic across node components.
+
+### Changed
+
+- **SimpleNode**: Port rendering now uses `applyPortOrder` and iterates the full port list, matching the behavior already present in WorkflowNode and GatewayNode.
+- **SquareNode**: Port rendering aligned with SimpleNode — all ports are visible by default, `portOrder` and `hiddenPorts` are respected, and node height is derived dynamically from the visible port count.
+
+### Internal
+
+- Replaced `$derived(() => fn())` getter anti-pattern with `$derived(fn())` across WorkflowNode, SimpleNode, and SquareNode.
+- Added unit tests for `getPortTop` and `isPortVisible` (34 tests passing).
