The spine-godot runtime documentation currently provides instructions for building the Godot editor and export templates for Godot 4.0.x and 4.1.x, including C# support. While there is no specific mention of Godot 4.5 in the provided documentation, the spine-godot runtime typically follows the upstream Godot releases. Therefore, it is likely that support for Godot 4.5 will be added in the future as the Godot version becomes stable and widely adopted.
