 		Kinematic bodies are special types of bodies that are meant to be user-controlled. They are not affected by physics at all; to other types of bodies, such as a character or a rigid body, these are the same as a static body. However, they have two main uses:
 		[b]Simulated motion:[/b] When these bodies are moved manually, either from code or from an [AnimationPlayer] (with [member AnimationPlayer.playback_process_mode] set to "physics"), the physics will automatically compute an estimate of their linear and angular velocity.

 		[PopupMenu] is a [Control] that displays a list of options. They are popular in toolbars or context menus.
 		[b]Incremental search:[/b] Like [ItemList] and [Tree], [PopupMenu] supports searching within the list while the control is focused. Press a key that matches the first letter of an item's name to select the first item starting with the given letter. After that point, there are two ways to perform incremental search: 1) Press the same key again before the timeout duration to select the next item starting with the same letter. 2) Press letter keys that match the rest of the word before the timeout duration to match to select the item in question directly. Both of these actions will be reset to the beginning of the list if the timeout duration has passed since the last keystroke was registered. You can adjust the timeout duration by changing [member ProjectSettings.gui/timers/incremental_search_max_interval_msec].
+		[b]Note:[/b] The ID values used for items are limited to 32 bits, not full 64 bits of [int]. This has a range of [code]-2^32[/code] to [code]2^32 - 1[/code], i.e. [code]-2147483648[/code] to [code]2147483647[/code].

 			If set to [code]Asynchronous[/code] and available on the target device, asynchronous compilation of shaders is enabled (in contrast to [code]Asynchronous[/code]).
 			That means that when a shader is first used under some new rendering situation, the game won't stall while such shader is being compiled. Instead, a fallback will be used and the real shader will be compiled in the background. Once the actual shader is compiled, it will be used the next times it's used to draw a frame.

+			Depending on the [member SpatialMaterial.async_mode] mode configured for a given material, the fallback will be an "ubershader" (the default) or just skip rendering any item it is applied to. In custom [ShaderMaterial]s, the async mode is set using [code]render_mode async_visible;[/code] (default) or [code]render_mode async_hidden;[/code] at the top of the shader.
 			An ubershader is a very complex shader, slow but suited to any rendering situation, that the engine generates internally so it can be used from the beginning while the traditional conditioned, optimized version of it is being compiled.
 			To reduce loading times after the project has been launched at least once, you can use [code]Asynchronous + Cache[/code]. This also causes the ubershaders to be cached into storage so they can be ready faster next time they are used (provided the platform provides support for it).
+			[b]Note:[/b] Asynchronous compilation requires driver support for the [code]GL_ARB_get_program_binary[/code] OpenGL extension. This extension is supported by all hardware that supports OpenGL 4.1 or higher as well as most hardware that supports OpenGL 3.3 or higher.
 			[b]Note:[/b] Asynchronous compilation is currently only supported for spatial (3D) and particle materials/shaders. CanvasItem (2D) shaders will not use asynchronous compilation even if this setting is set to [code]Asynchronous[/code] or [code]Asynchronous + Cache[/code].

 		[b]Note:[/b] Don't change a RigidBody's position every frame or very often. Sporadic changes work fine, but physics runs at a different granularity (fixed Hz) than usual rendering (process callback) and maybe even in a separate thread, so changing this from a process loop may result in strange behavior. If you need to directly affect the body's state, use [method _integrate_forces], which allows you to directly access the physics state.
 		If you need to override the default physics behavior, you can write a custom force integration function. See [member custom_integrator].

 		This node implements all the physics logic needed to simulate a car. It is based on the raycast vehicle system commonly found in physics engines. You will need to add a [CollisionShape] for the main body of your vehicle and add [VehicleWheel] nodes for the wheels. You should also add a [MeshInstance] to this node for the 3D model of your car but this model should not include meshes for the wheels. You should control the vehicle by using the [member brake], [member engine_force], and [member steering] properties and not change the position or orientation of this node directly.
