v0.6.0

[0.6.0] - 2026-04-02

Breaking

• Unified pointer events. 14 device/widget-specific event types
  replaced with 8 generic types: :press, :release, :move,
  :scroll, :enter, :exit, :double_click, :resize. All carry
  pointer type (:mouse/:touch/:pen), modifiers state, and
  optional finger ID for touch. Removed types: canvas_press,
  canvas_release, canvas_move, canvas_scroll, mouse_right_press,
  mouse_right_release, mouse_middle_press, mouse_middle_release,
  mouse_move, mouse_scroll, mouse_enter, mouse_exit,
  mouse_double_click, sensor_resize.

• Canvas element events unified. canvas_element_enter/leave/
  focused/blurred/drag/drag_end/key_press/key_release and
  canvas_element_click replaced with standard types using scoped IDs.
  Canvas elements look like regular widgets from the SDK's perspective.

• MouseEvent and TouchEvent removed. Subscription pointer
  events are now delivered as WidgetEvent structs with id set to
  the window ID and scope of [].

• mouse_area renamed to pointer_area. The widget, DSL macro,
  and wire type all use the new name.

• Window ID in scope chain. Window IDs are appended to the end of
  the scope list. Pattern matching with | _ at the end of scope
  naturally ignores the window for single-window apps.

• :scroll vs :scrolled. :scroll is pointer wheel input (with
  coordinates and deltas). :scrolled is scrollable container viewport
  state change. Previously both used :scroll.

• :start/:end alignment aliases removed. Use :left/:right/
  :top/:bottom/:center.

• Subscription functions renamed. on_mouse_move -> on_pointer_move,
  on_mouse_button -> on_pointer_button, on_mouse_scroll ->
  on_pointer_scroll, on_touch -> on_pointer_touch.

• Canvas auto-consumption removed. Canvas background pointer events
  now reach update/2 when opted in via on_press/on_move/etc.

• Renderer binary version bumped to 0.6.0.

Added

• Device awareness on pointer events. Plushie.Type.Pointer module
  with pointer_type (:mouse/:touch/:pen) and button types.
  Every pointer event includes pointer type, modifier state, and finger
  ID for touch.

• Window-qualified selector syntax. "main#form/save" targets a
  widget in a specific window. Works in test selectors and commands
  (Command.focus, Command.scroll_to, etc.).

• Widget state re-render. When a widget's handle_event/2 returns
  {:update_state, new_state}, the view is immediately re-rendered.
  Previously required an unrelated event to trigger the re-render.

• Mock canvas element click. click("#canvas-id/element-id") works
  in mock mode tests by detecting scoped IDs and verifying element
  existence.

• Mock sequential click fix. Sequential clicks on different widgets
  now work reliably in mock mode (synthetic event path replaces fragile
  focus+space approach).

• Coalescing for pointer events. :move (Replace), :scroll
  (Accumulate deltas), :scrolled (Replace), :resize (Replace).

Fixed

• Widget re-render on state change with window sync and error
  revert.
• Pre-existing decoder bugs: transition_complete missing from
  specs and missing scope extraction, sort data shape mismatch,
  pane_focus_cycle spec/decoder mismatch.
• plushie.build patches vendored iced subcrates when local source
  checkout exists. Handles file read errors in Cargo.toml parsing.

Changed

• Documentation overhaul. README rewritten, docs/README.md index
  added for hexdocs, CONTRIBUTING.md created. All em-dashes replaced
  with single dashes. Comprehensive docs for pointer events, device
  awareness, canvas touch, modifier patterns, window scope, and
  selector syntax.
