+The `set_accent_color` request dropped its `a` (alpha) argument. The accent color is now an opaque RGB triple `r, g, b` (each `uint` in `[0, 255]`); the alpha channel is no longer carried on the wire. Consumers must stop sending the trailing `a` argument and must not interpret accent color opacity from this request; opacity is outside the scope of the accent color setting.

+The `accent_color` event dropped its `a` (alpha) argument. The accent color is now reported as an opaque RGB triple `r, g, b` (each `uint` in `[0, 255]`); the alpha channel is no longer carried on the wire. Consumers must stop reading the trailing `a` argument and must not derive accent color opacity from this event; opacity is outside the scope of the accent color setting.

 #### `treeland-dde-shell-v1.xml`
 
 The manager request `set_xwindow_position_relative` is now documented as deprecated and non-functional: it has no effect and no callback is ever created. The file itself stays in place for now; the whole `treeland-dde-shell` protocol is slated for removal in a future release.

 管理器的 `set_xwindow_position_relative` 请求现标注为已废弃且不可用：请求无任何效果，也不会创建任何回调。文件暂保留原位；整个 `treeland-dde-shell` 协议计划在未来版本彻底移除。
