 ## OpenGL on macOS {#compat_osx}

-macOS (as of version 14) still provides OpenGL but it has been deprecated by
-Apple.  While the API is still available, it is poorly maintained and frequently
-develops new issues.  On modern systems, OpenGL is implemented on top of Metal
-and is not fully thread-safe.
+Support for OpenGL 3.2 and above was introduced with OS X 10.7 and even then
+only forward-compatible, core profile contexts are supported.  Support for
+OpenGL 4.1 was introduced with OS X 10.9, also limited to forward-compatible,
+core profile contexts.  There is also still no mechanism for requesting debug
+contexts or no-error contexts.  Versions of Mac OS X earlier than 10.7 support
+at most OpenGL version 2.1.

-macOS does not support OpenGL stereo rendering.  If the `GLFW_STEREO` hint is
-set to true, OpenGL context creation will always fail.
+Because of this, on OS X 10.7 and later, the `GLFW_CONTEXT_VERSION_MAJOR` and
+`GLFW_CONTEXT_VERSION_MINOR` hints will cause @ref glfwCreateWindow to fail if
+given version 3.0 or 3.1.  The `GLFW_OPENGL_PROFILE` hint must be set to
+`GLFW_OPENGL_CORE_PROFILE` when creating OpenGL 3.2 and later contexts.  The
+`GLFW_CONTEXT_DEBUG` and `GLFW_CONTEXT_NO_ERROR` hints are ignored.

-macOS only supports OpenGL core profile contexts that are forward-compatible,
-but the `GLFW_OPENGL_FORWARD_COMPAT` hint is ignored since GLFW 3.4.  Even if
-this hint is set to false (the default), a forward-compatible context will be
-returned if available.
-
-macOS does not support OpenGL debug contexts, no-error contexts or robustness.
-The `GLFW_CONTEXT_DEBUG`, `GLFW_CONTEXT_NO_ERROR` and `GLFW_CONTEXT_ROBUSTNESS`
-hints will be ignored and a context without these features will be returned.
-
-macOS does not flush OpenGL contexts when they are made non-current.  The
-`GLFW_CONTEXT_RELEASE_BEHAVIOR` hint is ignored and the release behavior will
-always be the equivalent of `GLFW_RELEASE_BEHAVIOR_NONE`.  If you need a context
-to be flushed, call `glFlush` before making it non-current.
+Also, on Mac OS X 10.6 and below, the `GLFW_CONTEXT_VERSION_MAJOR` and
+`GLFW_CONTEXT_VERSION_MINOR` hints will fail if given a version above 2.1,
+setting the `GLFW_OPENGL_PROFILE` or `GLFW_OPENGL_FORWARD_COMPAT` hints to
+a non-default value will cause @ref glfwCreateWindow to fail and the
+`GLFW_CONTEXT_DEBUG` hint is ignored.

 [TOC]


-## New features {#features}
+## Release notes for version 3.4 {#news_34}

-### Unlimited mouse buttons {#unlimited_mouse_buttons}
+### New features in version 3.4 {#features_34}

-GLFW now has an input mode which allows an unlimited number of mouse buttons to
-be reported by the mouse buttton callback, rather than just the associated
-[mouse button tokens](@ref buttons). This allows using mouse buttons with
-values over 8. For compatibility with older versions, the
-@ref GLFW_UNLIMITED_MOUSE_BUTTONS input mode needs to be set to make use of
-this.
+#### Cocoa NSView native access function {#native_cocoa_nsview_34}

-### Window hint for hardware acceleration {#acceleration}
+GLFW now provides the @ref glfwGetCocoaView native access function
+for returning the Cocoa NSView.
+
+
+#### Runtime platform selection {#runtime_platform_34}
+
+GLFW now supports being compiled for multiple backends and selecting between
+them at runtime with the @ref GLFW_PLATFORM init hint.  After initialization the
+selected platform can be queried with @ref glfwGetPlatform.  You can check if
+support for a given platform is compiled in with @ref glfwPlatformSupported.
+
+
+#### More standard cursor shapes {#standard_cursors_34}
+
+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 omnidirectional 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.
+
+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.
+
+For more information see @ref cursor_standard.
+
+
+#### Mouse event passthrough {#mouse_passthrough_34}
+
+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).
+
+
+#### Ability to get window title {#features_34_window_title}
+
+GLFW now supports querying the title of a window with the @ref glfwGetWindowTitle
+function.
+
+For more information see @ref window_title.
+
+
+#### Captured cursor mode {#captured_cursor_34}
+
+GLFW now supports confining the cursor to the window content area with the @ref
+GLFW_CURSOR_CAPTURED cursor mode.
+
+For more information see @ref cursor_mode.
+
+
+#### Support for custom heap memory allocator {#features_34_init_allocator}
+
+GLFW now supports plugging a custom memory allocator at initialization with @ref
+glfwInitAllocator.  The allocator is a struct of type @ref GLFWallocator with
+function pointers corresponding to the standard library functions `malloc`,
+`realloc` and `free`.
+
+For more information see @ref init_allocator.
+
+
+#### Window hint for framebuffer scaling {#scale_framebuffer_34}
+
+GLFW now allows provides the
+[GLFW_SCALE_FRAMEBUFFER](@ref GLFW_SCALE_FRAMEBUFFER_hint) window hint for
+controlling framebuffer scaling on platforms that handle scaling by keeping the
+window size the same while resizing the framebuffer.  The default value is to
+allow framebuffer scaling.
+
+This was already possible on macOS via the
+[GLFW_COCOA_RETINA_FRAMEBUFFER](@ref GLFW_COCOA_RETINA_FRAMEBUFFER_hint) window
+hint.  This hint is now another name for
+[GLFW_SCALE_FRAMEBUFFER](@ref GLFW_SCALE_FRAMEBUFFER_hint).
+
+For more information see @ref window_scale.
+
+
+#### Window hints for initial window position {#features_34_position_hint}
+
+GLFW now provides the @ref GLFW_POSITION_X and @ref GLFW_POSITION_Y window hints for
+specifying the initial position of the window.  This removes the need to create a hidden
+window, move it and then show it.  The default value of these hints is
+`GLFW_ANY_POSITION`, which selects the previous behavior.
+
+For more information see @ref window_pos.
+
+
+#### Support for keyboard access to Windows window menu {#features_34_win32_keymenu}
+
+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.
+
+
+#### Support for applying STARTUPINFO show command {#features_34_win32_showdefault}
+
+GLFW now provides the [GLFW_WIN32_SHOWDEFAULT](@ref GLFW_WIN32_SHOWDEFAULT_hint) window
+hint for applying the show command in the program's `STARTUPINFO` when showing the window
+for the first time.  This may be useful for the main window of a windowed-mode tool.
+
+
+#### Wayland libdecor decorations {#wayland_libdecor_34}
+
+GLFW now supports improved fallback window decorations via
+[libdecor](https://gitlab.freedesktop.org/libdecor/libdecor).
+
+Support for libdecor can be toggled before GLFW is initialized with the
+[GLFW_WAYLAND_LIBDECOR](@ref GLFW_WAYLAND_LIBDECOR_hint) init hint.  It is
+enabled by default.
+
+
+#### Window hint for Wayland app_id {#wayland_app_id_34}
+
+GLFW now supports specifying the app_id for a Wayland window using the
+[GLFW_WAYLAND_APP_ID](@ref GLFW_WAYLAND_APP_ID_hint) window hint string.
+
+
+#### Support for ANGLE rendering backend selection {#features_34_angle_backend}
+
+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][] to create OpenGL ES
+contexts.
+
+[ANGLE]: https://chromium.googlesource.com/angle/angle/

-## Caveats {#caveats}
+### Caveats for version 3.4 {#caveats}

-### Microsoft GDI software OpenGL ICD support {#gdi_opengl_icd}
+#### Multiple sets of native access functions {#native_34}
+
+Because GLFW now supports runtime selection of platform (window system), a library binary
+may export native access functions for multiple platforms.  Starting with version 3.4 you
+must not assume that GLFW is running on a platform just because it exports native access
+functions for it.  After initialization, you can query the selected platform with @ref
+glfwGetPlatform.
+
+
+#### Version string format has been changed {#version_string_34}
+
+Because GLFW now supports runtime selection of platform (window system), the version
+string returned by @ref glfwGetVersionString has been expanded.  It now contains the names
+of all APIs for all the platforms that the library binary supports.
+
+
+#### Joystick support is initialized on demand {#joysticks_34}
+
+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.
+
+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.
+
+To work around this, call any joystick function before waiting for events, for
+example by setting a [joystick callback](@ref joystick_event).
+
+
+#### Framebuffer may lack alpha channel on older Wayland systems {#wayland_alpha_34}
+
+On Wayland, when creating an EGL context on a machine lacking the new
+`EGL_EXT_present_opaque` extension, the @ref GLFW_ALPHA_BITS window hint will be
+ignored and the framebuffer will have no alpha channel.  This is because some
+Wayland compositors treat any buffer with an alpha channel as per-pixel
+transparent.
+
+If you want a per-pixel transparent window, see the
+[GLFW_TRANSPARENT_FRAMEBUFFER](@ref GLFW_TRANSPARENT_FRAMEBUFFER_hint) window
+hint.
+
+
+#### Tests and examples are disabled when built as a subproject {#standalone_34}
+
+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
+GLFW subdirectory.
+
+```cmake
+set(GLFW_BUILD_EXAMPLES ON CACHE BOOL "" FORCE)
+set(GLFW_BUILD_TESTS ON CACHE BOOL "" FORCE)
+add_subdirectory(path/to/glfw)
+```
+
+
+#### macOS main menu now created at initialization {#initmenu_34}
+
+GLFW now creates the main menu and completes the initialization of NSApplication
+during initialization.  Programs that do not want a main menu can disable it
+with the [GLFW_COCOA_MENUBAR](@ref GLFW_COCOA_MENUBAR_hint) init hint.
+
+
+#### CoreVideo dependency has been removed {#corevideo_34}
+
+GLFW no longer depends on the CoreVideo framework on macOS and it no longer
+needs to be specified during compilation or linking.
+
+
+#### Framebuffer transparency requires DWM transparency {#caveat_fbtransparency_34}
+
+GLFW no longer supports framebuffer transparency enabled via @ref
+GLFW_TRANSPARENT_FRAMEBUFFER on Windows 7 if DWM transparency is off
+(the Transparency setting under Personalization > Window Color).
+
+
+#### Empty events on X11 no longer round-trip to server {#emptyevents_34}
+
+Events posted with @ref glfwPostEmptyEvent now use a separate unnamed pipe
+instead of sending an X11 client event to the helper window.
+
+
+#### Microsoft GDI software OpenGL ICD support {#gdi_opengl_icd_34}

 GLFW now supports creating window when the Microsoft GDI software OpenGL ICD is
 the only available implementation.
 See [GLFW_ACCELERATION](@ref GLFW_ACCELERATION_hint) for more details.


-## Deprecations {#deprecations}
+### Deprecations in version 3.4 {#deprecations_34}

-## Removals {#removals}
+### Removals in 3.4 {#removals_34}

-## New symbols {#new_symbols}
+#### GLFW_VULKAN_STATIC CMake option has been removed {#vulkan_static_34}

-### New functions {#new_functions}
+This option was used to compile GLFW directly linked with the Vulkan loader, instead of
+using dynamic loading to get hold of `vkGetInstanceProcAddr` at initialization.  This is
+now done by calling the @ref glfwInitVulkanLoader function before initialization.

-### New types {#new_types}
+If you need backward compatibility, this macro can still be defined for GLFW 3.4 and will
+have no effect.  The call to @ref glfwInitVulkanLoader can be conditionally enabled in
+your code by checking the @ref GLFW_VERSION_MAJOR and @ref GLFW_VERSION_MINOR macros.

-### New constants {#new_constants}

- @ref GLFW_UNLIMITED_MOUSE_BUTTONS
+#### GLFW_USE_OSMESA CMake option has been removed {#osmesa_option_34}
+
+This option was used to compile GLFW for the Null platform.  The Null platform is now
+always supported.  To produce a library binary that only supports this platform, the way
+this CMake option used to do, you will instead need to disable the default platform for
+the target OS.  This means setting the @ref GLFW_BUILD_WIN32, @ref GLFW_BUILD_COCOA or
+@ref GLFW_BUILD_X11 CMake option to false.
+
+You can set all of them to false and the ones that don't apply for the target OS will be
+ignored.
+
+
+#### Support for the wl_shell protocol has been removed {#wl_shell_34}
+
+Support for the wl_shell protocol has been removed and GLFW now only supports
+the XDG-Shell protocol.  If your Wayland compositor does not support XDG-Shell
+then GLFW will fail to initialize.
+
