v0.6.0

[0.6.0] - 2026-04-02

Breaking changes

• Unified pointer events. Canvas-specific (canvas_press,
  canvas_release, canvas_move, canvas_scroll) and mouse area
  specific (mouse_right_press, mouse_middle_press, mouse_move,
  mouse_scroll, mouse_enter, mouse_exit, mouse_double_click)
  event families replaced with unified device-agnostic families:
  press, release, move, scroll, enter, exit,
  double_click. All carry pointer type, modifiers state, and
  optional finger ID for touch.

• Canvas element events unified. canvas_element_enter/leave/
  focused/blurred/drag/drag_end/key_press/key_release
  replaced with standard families (enter, exit, focused,
  blurred, drag, drag_end, key_press, key_release) using
  scoped IDs ("{canvas_id}/{element_id}").

• mouse_area widget renamed to pointer_area on the wire.

• Scrollable viewport event renamed from scroll to scrolled
  on the wire. scroll is now the pointer wheel event.

• sensor_resize event renamed to resize.

• :start/:end alignment aliases removed. Use :left/:right/
  :top/:bottom/:center. Unknown alignment values log a warning.

• Subscription wire types renamed. on_mouse_move/button/
  scroll and on_touch renamed to on_pointer_move/button/
  scroll/touch.

Added

• Device awareness on pointer events. Every pointer event includes
  pointer field ("mouse", "touch", "pen"), keyboard modifiers
  state ({shift, ctrl, alt, logo, command}), and finger ID for
  touch events.

• Canvas touch support. Canvas now handles FingerPressed,
  FingerMoved, and FingerLifted events with full hit testing, drag,
  and click detection. Touch events are emitted with pointer: "touch"
  and the finger ID.

• Modifier state tracking. Renderer tracks current keyboard
  modifier state and includes it on all outgoing pointer events.

• Mock mode canvas element click. click("#canvas-id/element-id")
  works in mock mode by detecting scoped IDs, finding the canvas,
  verifying the element exists, and emitting a click event.

• Renderer-side animation system. Transitions, springs, and
  sequences with animatable props across display, layout, and input
  widgets.

• Per-window scale_factor support.

• Window-scoped subscriptions. Subscription events include
  window_id for multi-window disambiguation.

• Widget-targeted scroll commands for specific scrollable widgets.

• Effect stubs for testing (register/unregister via wire protocol).

• Canvas element key events. key_press/key_release on focused
  elements when arrow_mode is "none".

• Canvas scoped IDs for all element events.

• Radio group accessibility role for canvas elements.

Fixed

• Mock mode modifier keys. Click/toggle actions in mock mode now
  extract modifiers from the interact payload instead of hardcoding
  empty modifiers.

• Mock mode sequential clicks. Replaced the fragile focus+space
  approach with direct synthetic event emission. Sequential clicks on
  different widgets now work reliably.

• Broken pipe handling. Ignore broken pipes during hello handshake.

Changed

• Upgraded to plushie-iced 0.8.1 (mouse_area cursor position callbacks).
• Renamed plushie_id to window_id throughout renderer codebase.
• Generic renderer pipeline with null renderer for mock mode.
• Extracted shared startup sequence into startup module.
