Godot 4.0 第四个 Alpha 版本已发布，更新内容主要是修复错误和改进功能。
The fourth Alpha version of Godot 4.0 has been released, and the update content is mainly to fix bugs and improve functions.
4.0 Alpha 4 download address: https://downloads.tuxfamily.org/godotengine/4.0/alpha4/ (The engine in the Alpha stage is still incomplete and not stable enough, and there will be major changes with the subsequent beta versions, so caution is advised Use. "Frozen features" only when entering beta stage)
One notable change is that this release has added support for OpenXR to the core. Godot has an OpenXR plugin, the code has now been ported to Godot's core. Better integration with Vulkan and other engine components is possible by porting OpenXR support to the core.
In addition to this, Godot 4.0 Alpha 4 brings 2D fixes, improved popup/menu handling, numerous GDScript fixes, several rendering fixes, different support for Visual Shader code, and other enhancements.

4.0 Alpha 4 下载地址：https://downloads.tuxfamily.org/godotengine/4.0/alpha4/（在 Alpha 阶段的引擎仍然不完整也不够稳定，且与后续的 beta 版本会有较大的变化，建议谨慎使用。只有进入 Beta 阶段才会“冻结功能”）
值得关注的一项变化是，此版本已将对 OpenXR 的支持添加到核心。Godot 有一个 OpenXR 插件，该代码现在已经被移植到 Godot 的核心。通过将 OpenXR 支持移植到核心，可以更好地与 Vulkan 和其他引擎组件集成。
除此之外，Godot 4.0 Alpha 4 还带来了 2D 修复、改进的弹出窗口/菜单处理、大量 GDScript 修复、多项渲染修复、对 Visual Shader 代码的不同支持，以及其他增强功能。
