 doesn't, that might be a separate bug.

 handles and other pointers are valid.

+The button fields are `a`, `b`, `c`, `d`, `back`, `start`, `guide`, `dpup`,

+The axis fields are `leftx`, `lefty`, `rightx`, `righty`, `lefttrigger` and
+`righttrigger`.
+
+The value of an axis or button field can be a joystick button, a joystick axis,
+a hat bitmask or empty.  Joystick buttons are specified as `bN`, for example
+`b2` for the third button.  Joystick axes are specified as `aN`, for example
+`a7` for the eighth button.  Joystick hat bit masks are specified as `hN.N`, for
+example `h0.8` for left on the first hat.  More than one bit may be set in the
+mask.
+
+Before an axis there may be a `+` or `-` range modifier, for example `+a3` for
+the positive half of the fourth axis.  This restricts input to only the positive
+or negative halves of the joystick axis.  After an axis or half-axis there may
+be the `~` inversion modifier, for example `a2~` or `-a7~`.  This negates the
+values of the gamepad axis.
+
+The hat bit mask match the [hat states](@ref hat_state) in the joystick
+functions.
+
+There is also the special `platform` field that specifies which platform the
+mapping is valid for.  Possible values are `Windows`, `Mac OS X` and `Linux`.
+
+Below is an example of what a gamepad mapping might look like.  It is the

-@subsection news_32_vulkan Support for Vulkan
+@subsubsection standard_cursors_34 More standard cursors

-GLFW now supports basic integration with Vulkan with @ref glfwVulkanSupported,
-@ref glfwGetRequiredInstanceExtensions, @ref glfwGetInstanceProcAddress, @ref
-glfwGetPhysicalDevicePresentationSupport and @ref glfwCreateWindowSurface.
-Vulkan header inclusion can be selected with
-[GLFW_INCLUDE_VULKAN](@ref build_macros).
+GLFW now provides the standard cursor shapes @ref GLFW_RESIZE_NWSE_CURSOR and
+@ref GLFW_RESIZE_NESW_CURSOR for diagonal resizing, @ref GLFW_RESIZE_ALL_CURSOR
+for omni-directional resizing and @ref GLFW_NOT_ALLOWED_CURSOR for showing an
+action is not allowed.

+Unlike the original set, these shapes may not be available everywhere and
+creation will then fail with the new @ref GLFW_CURSOR_UNAVAILABLE error.

-@subsection news_32_setwindowmonitor Window mode switching
+The cursors for horizontal and vertical resizing are now referred to as @ref
+GLFW_RESIZE_EW_CURSOR and @ref GLFW_RESIZE_NS_CURSOR, and the pointing hand
+cursor is now referred to as @ref GLFW_POINTING_HAND_CURSOR.  The older names
+are still available.

-GLFW now supports switching between windowed and full screen modes and updating
-the monitor and desired resolution and refresh rate of full screen windows with
-@ref glfwSetWindowMonitor.
+For more information see @ref cursor_standard.


-@subsection news_32_maximize Window maxmimization support
+@subsubsection mouse_passthrough_34 Mouse event passthrough

-GLFW now supports window maximization with @ref glfwMaximizeWindow and the
-[GLFW_MAXIMIZED](@ref window_attribs_wnd) window hint and attribute.
+GLFW now provides the [GLFW_MOUSE_PASSTHROUGH](@ref GLFW_MOUSE_PASSTHROUGH_hint)
+window hint for making a window transparent to mouse input, lettings events pass
+to whatever window is behind it.  This can also be changed after window
+creation with the matching [window attribute](@ref GLFW_MOUSE_PASSTHROUGH_attrib).


-@subsection news_32_focus Window input focus control
+@subsubsection features_34_angle_backend Support for ANGLE rendering backend selection

-GLFW now supports giving windows input focus with @ref glfwFocusWindow.
+GLFW now provides the
+[GLFW_ANGLE_PLATFORM_TYPE](@ref GLFW_ANGLE_PLATFORM_TYPE_hint) init hint for
+requesting a specific rendering backend when using
+[ANGLE](https://chromium.googlesource.com/angle/angle/) to create OpenGL ES
+contexts.


-@subsection news_32_sizelimits Window size limit support
+@subsubsection features_34_win32_keymenu Support for keyboard access to Windows window menu

-GLFW now supports setting both absolute and relative window size limits with
-@ref glfwSetWindowSizeLimits and @ref glfwSetWindowAspectRatio.
+GLFW now provides the
+[GLFW_WIN32_KEYBOARD_MENU](@ref GLFW_WIN32_KEYBOARD_MENU_hint) window hint for
+enabling keyboard access to the window menu via the Alt+Space and
+Alt-and-then-Space shortcuts.  This may be useful for more GUI-oriented
+applications.


-@subsection news_32_keyname Localized key names
+@subsection caveats_34 Caveats for version 3.4

-GLFW now supports querying the localized name of printable keys with @ref
-glfwGetKeyName, either by key token or by scancode.
+@subsubsection joysticks_34 Joystick support is initialized on demand

+The joystick part of GLFW is now initialized when first used, primarily to work
+around faulty Windows drivers that cause DirectInput to take up to several
+seconds to enumerate devices.

-@subsection news_32_waittimeout Wait for events with timeout
+This change will usually not be observable.  However, if your application waits
+for events without having first called any joystick function or created any
+visible windows, the wait may never unblock as GLFW may not yet have subscribed
+to joystick related OS events.

-GLFW now supports waiting for events for a set amount of time with @ref
-glfwWaitEventsTimeout.
+To work around this, call any joystick function before waiting for events, for
+example by setting a [joystick callback](@ref joystick_event).


-@subsection news_32_icon Window icon support
+@subsubsection standalone_34 Tests and examples are disabled when built as a sub-project

-GLFW now supports setting the icon of windows with @ref glfwSetWindowIcon.
+GLFW now does not build the tests and examples when it is added as
+a subdirectory of another CMake project.  To enable these, set the @ref
+GLFW_BUILD_TESTS and @ref GLFW_BUILD_EXAMPLES cache variables before adding the

-client area of a window, with @ref glfwGetWindowFrameSize.
-
-@see [Window size](@ref window_size)
-
-
-@subsection news_31_autoiconify Simultaneous multi-monitor rendering
-
-GLFW now supports disabling auto-iconification of full screen windows with
-the [GLFW_AUTO_ICONIFY](@ref window_hints_wnd) window hint.  This is intended
-for people building multi-monitor installations, where you need windows to stay
-in full screen despite losing input focus.
-
-
-@subsection news_31_floating Floating windows
-
-GLFW now supports floating windows, also called topmost or always on top, for
-easier debugging with the [GLFW_FLOATING](@ref window_hints_wnd) window hint.
-
-
-@subsection news_31_focused Initially unfocused windows
-
-GLFW now supports preventing a windowed mode window from gaining input focus on
-creation, with the [GLFW_FOCUSED](@ref window_hints_wnd) window hint.
-
-
-@subsection news_31_direct Direct access for window attributes and cursor position
-
-GLFW now queries the window input focus, visibility and iconification attributes
-and the cursor position directly instead of returning cached data.
-
-
-@subsection news_31_charmods Character with modifiers callback
-
-GLFW now provides a callback for character events with modifier key bits.  The
-callback is set with @ref glfwSetCharModsCallback.  Unlike the regular character
-callback, this will report character events that will not result in a character
-being input, for example if the Control key is held down.
-
-@see @ref input_char
-
-
-@subsection news_31_single Single buffered framebuffers
-
-GLFW now supports the creation of single buffered windows, with the
-[GLFW_DOUBLEBUFFER](@ref window_hints_fb) window hint.
-
-
-@subsection news_31_glext Macro for including extension header
-
-GLFW now includes the extension header appropriate for the chosen OpenGL or
-OpenGL ES header when [GLFW_INCLUDE_GLEXT](@ref build_macros) is defined.  GLFW
-does not provide these headers.  They must be provided by your development
-environment or your OpenGL or OpenGL ES SDK.
-
-
-@subsection news_31_release Context release behaviors
-
-GLFW now supports controlling whether the pipeline is flushed when a context is
-made non-current, with the
-[GLFW_CONTEXT_RELEASE_BEHAVIOR](@ref window_hints_ctx) window hint, provided the
-machine supports the `GL_KHR_context_flush_control` extension.
-
-
-@subsection news_31_wayland (Experimental) Wayland support
-
-GLFW now has an _experimental_ Wayland display protocol backend that can be
-selected on Linux with a CMake option.

-@section news_30 New features in 3.0
-
-These are the release highlights.  For a full list of changes see the
-[version history](http://www.glfw.org/changelog.html).
-
-
-@subsection news_30_cmake CMake build system
-
-GLFW now uses the CMake build system instead of the various makefiles and
-project files used by earlier versions.  CMake is available for all platforms
-supported by GLFW, is present in most package systems and can generate
-makefiles and/or project files for most popular development environments.
-
-For more information on how to use CMake, see the
-[CMake manual](http://cmake.org/cmake/help/documentation.html).
-
-
-@subsection news_30_multiwnd Multi-window support
-
-GLFW now supports the creation of multiple windows, each with their own OpenGL
-or OpenGL ES context, and all window functions now take a window handle.  Event
-callbacks are now per-window and are provided with the handle of the window that
-received the event.  The @ref glfwMakeContextCurrent function has been added to
-select which context is current on a given thread.
-
-
-@subsection news_30_multimon Multi-monitor support
-
-GLFW now explicitly supports multiple monitors.  They can be enumerated with
-@ref glfwGetMonitors, queried with @ref glfwGetVideoModes, @ref
-glfwGetMonitorPos, @ref glfwGetMonitorName and @ref glfwGetMonitorPhysicalSize,
-and specified at window creation to make the newly created window full screen on
-that specific monitor.
-
-
-@subsection news_30_unicode Unicode support
-
-All string arguments to GLFW functions and all strings returned by GLFW now use
-the UTF-8 encoding.  This includes the window title, error string, clipboard
-text, monitor and joystick names as well as the extension function arguments (as
-ASCII is a subset of UTF-8).
-
-
-@subsection news_30_clipboard Clipboard text I/O
-
-GLFW now supports reading and writing plain text to and from the system
-clipboard, with the @ref glfwGetClipboardString and @ref glfwSetClipboardString
-functions.
-
-
-@subsection news_30_gamma Gamma ramp support
-
-GLFW now supports setting and reading back the gamma ramp of monitors, with the
-@ref glfwGetGammaRamp and @ref glfwSetGammaRamp functions.  There is also @ref
-glfwSetGamma, which generates a ramp from a gamma value and then sets it.
-
-
-@subsection news_30_gles OpenGL ES support
-
-GLFW now supports the creation of OpenGL ES contexts, by setting the
-`GLFW_CLIENT_API` window hint to `GLFW_OPENGL_ES_API`, where creation of such
-contexts are supported.  Note that GLFW _does not implement_ OpenGL ES, so your
-driver must provide support in a way usable by GLFW.  Modern Nvidia and Intel
-drivers support creation of OpenGL ES context using the GLX and WGL APIs, while
-AMD provides an EGL implementation instead.
-
-
-@subsection news_30_egl (Experimental) EGL support
-
-GLFW now has an experimental EGL context creation back end that can be selected
-through CMake options.
-
-
-@subsection news_30_hidpi High-DPI support
-
-GLFW now supports high-DPI monitors on both Windows and OS X, giving windows full
-resolution framebuffers where other UI elements are scaled up.  To achieve this,
-@ref glfwGetFramebufferSize and @ref glfwSetFramebufferSizeCallback have been
-added.  These work with pixels, while the rest of the GLFW API works with screen
-coordinates.  This is important as OpenGL uses pixels, not screen coordinates.
-
-
-@subsection news_30_error Error callback
-
-GLFW now has an error callback, which can provide your application with much
-more detailed diagnostics than was previously possible.  The callback is passed
-an error code and a description string.
-
-
-@subsection news_30_wndptr Per-window user pointer
-
-Each window now has a user-defined pointer, retrieved with @ref
-glfwGetWindowUserPointer and set with @ref glfwSetWindowUserPointer, to make it
-easier to integrate GLFW into C++ code.
-
-
-@subsection news_30_iconifyfun Window iconification callback
-
-Each window now has a callback for iconification and restoration events,
-which is set with @ref glfwSetWindowIconifyCallback.
-
-
-@subsection news_30_wndposfun Window position callback
-
-Each window now has a callback for position events, which is set with @ref
-glfwSetWindowPosCallback.
-
-
-@subsection news_30_wndpos Window position query
-
-The position of a window can now be retrieved using @ref glfwGetWindowPos.
-
-
-@subsection news_30_focusfun Window focus callback
-
-Each windows now has a callback for focus events, which is set with @ref
-glfwSetWindowFocusCallback.
-
-
-@subsection news_30_enterleave Cursor enter/leave callback
-
-Each window now has a callback for when the mouse cursor enters or leaves its
-client area, which is set with @ref glfwSetCursorEnterCallback.
-
-
-@subsection news_30_wndtitle Initial window title
-
-The title of a window is now specified at creation time, as one of the arguments
-to @ref glfwCreateWindow.
-
-
-@subsection news_30_hidden Hidden windows
-
-Windows can now be hidden with @ref glfwHideWindow, shown using @ref
-glfwShowWindow and created initially hidden with the `GLFW_VISIBLE` window hint.
-This allows for off-screen rendering in a way compatible with most drivers, as
-well as moving a window to a specific position before showing it.
-
-
-@subsection news_30_undecorated Undecorated windows
-
-Windowed mode windows can now be created without decorations, e.g. things like
-a frame, a title bar, with the `GLFW_DECORATED` window hint.  This allows for
-the creation of things like splash screens.
-
-
-@subsection news_30_keymods Modifier key bit masks
-
-[Modifier key bit mask](@ref mods) parameters have been added to the
-[mouse button](@ref GLFWmousebuttonfun) and [key](@ref GLFWkeyfun) callbacks.
-
-
-@subsection news_30_scancode Platform-specific scancodes
-
-A scancode parameter has been added to the [key callback](@ref GLFWkeyfun). Keys
-that don't have a [key token](@ref keys) still get passed on with the key
-parameter set to `GLFW_KEY_UNKNOWN`.  These scancodes will vary between machines
-and are intended to be used for key bindings.

+@section vulkan_loader Linking against the Vulkan loader
+
+By default, GLFW will look for the Vulkan loader on demand at runtime via its
+standard name (`vulkan-1.dll` on Windows, `libvulkan.so.1` on Linux and other
+Unix-like systems and `libvulkan.1.dylib` on macOS).  This means that GLFW does
+not need to be linked against the loader.  However, it also means that if you
+are using the static library form of the Vulkan loader GLFW will either fail to
+find it or (worse) use the wrong one.
+
+The @ref GLFW_VULKAN_STATIC CMake option makes GLFW call the Vulkan loader
+directly instead of dynamically loading it at runtime.  Not linking against the
+Vulkan loader will then be a compile-time error.
+
+@macos Because the Vulkan loader and ICD are not installed globally on macOS,
+you need to set up the application bundle according to the LunarG SDK
+documentation.  This is explained in more detail in the
