v0.16.1

• Added logging through log. Logging will become more extensive over time.
• On X11 and Windows, the window's DPI factor is guessed before creating the window. This greatly cuts back on unsightly auto-resizing that would occur immediately after window creation.
• Fixed X11 backend compilation for environments where c_char is unsigned.

v0.16.0

• Windows additionally has WindowBuilderExt::with_no_redirection_bitmap.
• Breaking: Removed VirtualKeyCode::LMenu and VirtualKeyCode::RMenu; Windows now generates VirtualKeyCode::LAlt and VirtualKeyCode::RAlt instead.
• On X11, exiting fullscreen no longer leaves the window in the monitor's top left corner.
• Breaking: Window::hidpi_factor has been renamed to Window::get_hidpi_factor for better consistency. WindowEvent::HiDPIFactorChanged has been renamed to WindowEvent::HiDpiFactorChanged. DPI factors are always represented as f64 instead of f32 now.
• The Windows backend is now DPI aware. WindowEvent::HiDpiFactorChanged is implemented, and MonitorId::get_hidpi_factor and Window::hidpi_factor return accurate values.
• Implemented WindowEvent::HiDpiFactorChanged on X11.
• On macOS, Window::set_cursor_position is now relative to the client area.
• On macOS, setting the maximum and minimum dimensions now applies to the client area dimensions rather than to the window dimensions.
• On iOS, MonitorId::get_dimensions has been implemented and both MonitorId::get_hidpi_factor and Window::get_hidpi_factor return accurate values.
• On Emscripten, MonitorId::get_hidpi_factor now returns the same value as Window::get_hidpi_factor (it previously would always return 1.0).
• Breaking: The entire API for sizes, positions, etc. has changed. In the majority of cases, winit produces and consumes positions and sizes as LogicalPosition and LogicalSize, respectively. The notable exception is MonitorId methods, which deal in PhysicalPosition and PhysicalSize. See the documentation for specifics and explanations of the types. Additionally, winit automatically conserves logical size when the DPI factor changes.
• Breaking: All deprecated methods have been removed. For Window::platform_display and Window::platform_window, switch to the appropriate platform-specific WindowExt methods. For Window::get_inner_size_points and Window::get_inner_size_pixels, use the LogicalSize returned by Window::get_inner_size and convert as needed.
• HiDPI support for Wayland.
• EventsLoop::get_available_monitors and EventsLoop::get_primary_monitor now have identical counterparts on Window, so this information can be acquired without an EventsLoop borrow.
• AvailableMonitorsIter now implements Debug.
• Fixed quirk on macOS where certain keys would generate characters at twice the normal rate when held down.
• On X11, all event loops now share the same XConnection.
• Breaking: Window::set_cursor_state and CursorState enum removed in favor of the more composable Window::grab_cursor and Window::hide_cursor. As a result, grabbing the cursor no longer automatically hides it; you must call both methods to retain the old behavior on Windows and macOS. Cursor::NoneCursor has been removed, as it's no longer useful.
• Breaking: Window::set_cursor_position now returns Result<(), String>, thus allowing for Box<Error> conversion via ?.

v0.15.1

• On X11, the Moved event is no longer sent when the window is resized without changing position.
• MouseCursor and CursorState now implement Default.
• WindowBuilder::with_resizable implemented for Windows, X11, Wayland, and macOS.
• Window::set_resizable implemented for Windows, X11, Wayland, and macOS.
• On X11, if the monitor's width or height in millimeters is reported as 0, the DPI is now 1.0 instead of +inf.
• On X11, the environment variable WINIT_HIDPI_FACTOR has been added for overriding DPI factor.
• On X11, enabling transparency no longer causes the window contents to flicker when resizing.
• On X11, with_override_redirect now actually enables override redirect.
• macOS now generates VirtualKeyCode::LAlt and VirtualKeyCode::RAlt instead of None for both.
• On macOS, VirtualKeyCode::RWin and VirtualKeyCode::LWin are no longer switched.
• On macOS, windows without decorations can once again be resized.
• Fixed race conditions when creating an EventsLoop on X11, most commonly manifesting as "[xcb] Unknown sequence number while processing queue".
• On macOS, CursorMoved and MouseInput events are only generated if they occurs within the window's client area.
• On macOS, resizing the window no longer generates a spurious MouseInput event.

v0.15.0

• Icon::to_cardinals is no longer public, since it was never supposed to be.
• Wayland: improve diagnostics if initialization fails
• Fix some system event key doesn't work when focused, do not block keyevent forward to system on macOS
• On X11, the scroll wheel position is now correctly reset on i3 and other WMs that have the same quirk.
• On X11, Window::get_current_monitor now reliably returns the correct monitor.
• On X11, Window::hidpi_factor returns values from XRandR rather than the inaccurate values previously queried from the core protocol.
• On X11, the primary monitor is detected correctly even when using versions of XRandR less than 1.5.
• MonitorId now implements Debug.
• Fixed bug on macOS where using with_decorations(false) would cause set_decorations(true) to produce a transparent titlebar with no title.
• Implemented MonitorId::get_position on macOS.
• On macOS, Window::get_current_monitor now returns accurate values.
• Added WindowBuilderExt::with_resize_increments to macOS.
• Breaking: On X11, WindowBuilderExt::with_resize_increments and WindowBuilderExt::with_base_size now take u32 values rather than i32.
• macOS keyboard handling has been overhauled, allowing for the use of dead keys, IME, etc. Right modifier keys are also no longer reported as being left.
• Added the Window::set_ime_spot(x: i32, y: i32) method, which is implemented on X11 and macOS.
• Breaking: os::unix::WindowExt::send_xim_spot(x: i16, y: i16) no longer exists. Switch to the new Window::set_ime_spot(x: i32, y: i32), which has equivalent functionality.
• Fixed detection of Pause and Scroll keys on Windows.
• On Windows, alt-tabbing while the cursor is grabbed no longer makes it impossible to re-grab the cursor.
• On Windows, using CursorState::Hide when the cursor is grabbed now ungrabs the cursor first.
• Implemented MouseCursor::NoneCursor on Windows.
• Added WindowBuilder::with_always_on_top and Window::set_always_on_top. Implemented on Windows, macOS, and X11.
• On X11, WindowBuilderExt now has with_class, with_override_redirect, and with_x11_window_type to allow for more control over window creation. WindowExt additionally has set_urgent.
• More hints are set by default on X11, including _NET_WM_PID and WM_CLIENT_MACHINE. Note that prior to this, the WM_CLASS hint was automatically set to whatever value was passed to with_title. It's now set to the executable name to better conform to expectations and the specification; if this is undesirable, you must explicitly use WindowBuilderExt::with_class.

v0.14.0

• Created the Copy, Paste and Cut VirtualKeyCodes and added support for them on X11 and Wayland
• Fix .with_decorations(false) in macOS
• On Mac, NSWindow and supporting objects might be alive long after they were closed which resulted in apps consuming more heap then needed. Mainly it was affecting multi window applications. Not expecting any user visible change of behaviour after the fix.
• Fix regression of Window platform extensions for macOS where NSFullSizeContentViewWindowMask was not being correctly applied to .fullsize_content_view.
• Corrected get_position on Windows to be relative to the screen rather than to the taskbar.
• Corrected Moved event on Windows to use position values equivalent to those returned by get_position. It previously supplied client area positions instead of window positions, and would additionally interpret negative values as being very large (around u16::MAX).
• Implemented Moved event on macOS.
• On X11, the Moved event correctly use window positions rather than client area positions. Additionally, a stray Moved that unconditionally accompanied Resized with the client area position relative to the parent has been eliminated; Moved is still received alongside Resized, but now only once and always correctly.
• On Windows, implemented all variants of DeviceEvent other than Text. Mouse DeviceEvents are now received even if the window isn't in the foreground.
• DeviceId on Windows is no longer a unit struct, and now contains a u32. For WindowEvents, this will always be 0, but on DeviceEvents it will be the handle to that device. DeviceIdExt::get_persistent_identifier can be used to acquire a unique identifier for that device that persists across replugs/reboots/etc.
• Corrected run_forever on X11 to stop discarding Awakened events.
• Various safety and correctness improvements to the X11 backend internals.
• Fixed memory leak on X11 every time the mouse entered the window.
• On X11, drag and drop now works reliably in release mode.
• Added WindowBuilderExt::with_resize_increments and WindowBuilderExt::with_base_size to X11, allowing for more optional hints to be set.
• Rework of the wayland backend, migrating it to use Smithay's Client Toolkit.
• Added WindowBuilder::with_window_icon and Window::set_window_icon, finally making it possible to set the window icon on Windows and X11. The icon_loading feature can be enabled to allow for icons to be easily loaded; see example program window_icon.rs for usage.
• Windows additionally has WindowBuilderExt::with_taskbar_icon and WindowExt::set_taskbar_icon.
• On Windows, fix panic when trying to call set_fullscreen(None) on a window that has not been fullscreened prior.

v0.13.0

• Implement WindowBuilder::with_maximized, Window::set_fullscreen, Window::set_maximized and Window::set_decorations for MacOS.
• Implement WindowBuilder::with_maximized, Window::set_fullscreen, Window::set_maximized and Window::set_decorations for Windows.
• On Windows, WindowBuilder::with_fullscreen no longer changing monitor display resolution.
• Overhauled X11 window geometry calculations. get_position and set_position are more universally accurate across different window managers, and get_outer_size actually works now.
• Fixed SIGSEGV/SIGILL crashes on macOS caused by stabilization of the ! (never) type.
• Implement WindowEvent::HiDPIFactorChanged for macOS
• On X11, input methods now work completely out of the box, no longer requiring application developers to manually call setlocale. Additionally, when input methods are started, stopped, or restarted on the server end, it's correctly handled.
• Implemented Refresh event on Windows.
• Properly calculate the minimum and maximum window size on Windows, including window decorations.
• Map more MouseCursor variants to cursor icons on Windows.
• Corrected get_position on macOS to return outer frame position, not content area position.
• Corrected set_position on macOS to set outer frame position, not content area position.
• Added get_inner_position method to Window, which gets the position of the window's client area. This is implemented on all applicable platforms (all desktop platforms other than Wayland, where this isn't possible).
• Breaking: the Closed event has been replaced by CloseRequested and Destroyed. To migrate, you typically just need to replace all usages of Closed with CloseRequested; see example programs for more info. The exception is iOS, where Closed must be replaced by Destroyed.
