+Changes in FLTK 1.4.0                            Released: ??? ?? 2022
+
+  General Information about this Release
+
+  - FLTK 1.4.0 is based on FLTK 1.3.4 (released Nov 15 2016),
+    see CHANGES_1.3.txt for more information.
+
+  - CMake is the primary supported build system in FLTK 1.4.0 and later.
+    CMake can be used to generate Makefiles, IDE project files, and
+    several other build systems by using different "generators" provided
+    by CMake (for instance Ninja, CodeBlocks, Eclipse, KDevelop3, Xcode, etc.).
+    See README.CMake.txt for more information.
+
+  - autoconf/configure is still supported by the FLTK team for backwards
+    compatibility with older systems that lack CMake support.
+
+  - FLTK 1.4 introduces a new platform, Wayland, available for recent Linux
+    distributions and FreeBSD. More information in README.Wayland.txt
+
+  New Features and Extensions
+
+  - X11 and Wayland platforms: Added support of HiDPI displays. FLTK apps
+    detect the current display scaling factor and use it to scale all windows.
+  - MSWindows platform: FLTK applications detect the display scaling factor and
+    automatically scale their GUI accordingly. This effectively renders WIN32
+    FLTK apps "per-monitor DPI-aware" whereas they were "DPI-unaware" before.
+  - Dynamical GUI rescaling: it is possible on all platforms to rescale all
+    FLTK windows mapped to a screen by typing ctrl-'+' (enlarge), ctrl-'-'
+    (shrink) or ctrl-'0' (back to starting scaling factor value). Under macOS,
+    the corresponding keystrokes are cmd-'+', cmd-'-', cmd-'0'. The resulting
+    GUI scaling factor (e.g., 170 %) transiently appears in a yellow popup window.
+    Use new Fl::option() item OPTION_SHOW_SCALING to turn on/off these popups.
+    Windows moved between screens adjust to the scaling factor of their screen.
+    This supports desktops mixing screens with distinct resolutions.
+    In addition, use environment variable FLTK_SCALING_FACTOR to further adjust
+    the starting scaling factor of all FLTK apps.
+  - New Fl_Flex class to layout one row or one column of widgets.
+  - New Fl::keyboard_screen_scaling(0) call stops recognition of ctrl/+/-/0/
+    keystrokes as scaling all windows of a screen.
+  - New member function Fl_Image::scale(int width, int height) to set
+    the drawing size of an image independently from its data size. The
+    same function was previously available only for class Fl_Shared_Image
+    and with FL_ABI_VERSION >= 10304. New member functions Fl_Image::data_w()
+    and Fl_Image::data_h() give the width and height of the image data.
+  - New member functions Fl_Widget::bind_image(Fl_Image *img) and
+    Fl_Widget::bind_deimage(Fl_Image *img) to bind an image to a widget, that is,
+    to set an image to be used as part of the widget label and also
+    to be deleted when the widget is deleted.
+  - New Fl_SVG_Image class: gives support of scalable vector graphics images
+    to FLTK using the nanosvg software.
+  - New Fl_ICO_Image class to read Windows .ico icon files.
+  - New classes Fl_SVG_File_Surface and Fl_EPS_File_Surface to save any FLTK
+    graphics to SVG or EPS files, respectively.
+  - Fl_Button now supports a compact flag that visually groups closely set 
+    buttons into keypads.
+  - Fl_Tabs now supports close buttons for individual tabs.
+  - Fl_Tabs now supports four different modes for handling an
+    overflowing number of tabs.
+  - New constructor for creating Fl_Preferences files with flags for the
+    correct locale and for overwriting existing files.
+  - Windows platform: added support for using a manifest to set the
+    application's level of DPI awareness (issue #309).
+  - class Fl_Native_File_Chooser on the X11/Wayland platform relies on external
+    commands zenity (PR #599), or kdialog (issue #278), or on the GTK library
+    to construct file dialogs. New "Preview" switch added to the GTK dialog.
+    The libgtk-based dialog uses in priority the file chooser dialog
+    of GTK version 3 when available on the running platform, and falls back
+    to version 2 when V3 is not available. In contrast, GTK version 2 was used
+    in priority by FLTK 1.3.x. New FL::option() item OPTION_FNFC_USES_ZENITY
+    to turn on/off use of zenity-based file dialogs.
+  - The undocumented feature FLTK_CONSOLIDATE_MOTION is now OFF on X11 and
+    removed on macOS. In FLTK 1.3 this feature has been ON on X11. The macro can now
+    be set on the compiler commandline and can be used to reduce the number
+    of mouse move events sent to the application but it may be unreliable.
+    Recommendation: let it switched OFF unless you really need it.
+  - New function fl_capture_window() to capture the content of a rectangular
+    zone of a mapped window and return it as an Fl_RGB_Image. It improves
+    with HighDPI displays what can be done with fl_read_image().
+  - The Windows platform now draws oblique and curved lines in antialiased
+    form. The new function void fl_antialias(int state); allows to turn off
+    or on such antialiased drawing. The new function int fl_antialias(); returns
+    whether line and curve drawing is currently antialiased.
+  - The border radius of "rounded" box types can be limited and
+    the shadow width of "shadow" box types can be configured (issue #130).
+    See Fl::box_border_radius_max() and Fl::box_shadow_width().
+  - New fl_putenv() is a cross-platform putenv() wrapper (see docs).
+  - New public variable Fl_Image::register_images_done allows an app. to detect
+    whether function fl_register_images() has been called.
+  - Fix Fl::add_timeout() under Linux (STR 3516).
+  - Fix early timeouts in Fl_Clock seen in some environments (STR 3516).
+  - Fl_Printer::begin_job() uses by default the Gnome print dialog on the X11
+    platform when the GTK library is available at run-time. That can be turned off
+    with Fl::option(OPTION_PRINTER_USES_GTK, false).
+  - New member functions Fl_Paged_Device::begin_job() and begin_page()
+    replace start_job() and start_page(). The start_... names are maintained
+    for API compatibility.
+  - OpenGL draws text using textures on all platforms, when the necessary
+    hardware support is present (a backup mechanism is available in absence
+    of this support). Thus, all text drawable in Fl_Window's can be drawn
+    in Fl_Gl_Window's (STR#3450).
+  - New member functions Fl::program_should_quit(void),
+    and Fl::program_should_quit(int) to support detection by the library
+    of a request to terminate cleanly the program.
+  - MacOS platform: the processing of the application menu's "Quit" item
+    has been changed. With FLTK 1.3.x, the application terminated when all
+    windows were closed even before Fl::run() or Fl::wait() could return.
+    With FLTK 1.4, Fl::run() returns so the app follows its normal termination path.
+  - FLTK apps on the MacOS platform contain automatically a Window menu, which,
+    under MacOS ≥ 10.12, allows to group/ungroup windows in tabbed form. The new
+    Fl_Sys_Menu_Bar::window_menu_style() function allows to specify various
+    styles for the Window menu, even not to create it.
+  - New function: int fl_open_ext(const char* fname, int binary, int oflags, ...)
+    to control the opening of files in binary/text mode in a cross-platform way.
+  - Fix for issue #247 : loading SVG image with BOM.
+  - Fl_Text_Selection got a new method length() and returns 0 in length()
+    and in all offsets (start(), end(), position()) if no text is selected
+    (selected() == false). The behavior in FLTK 1.3 and earlier versions
+    (returning undefined values if !selected()) was confusing.
+  - New method Fl_Group::bounds() replaces Fl_Group::sizes() which is now
+    deprecated. Fl_Group::bounds() uses the new class Fl_Rect that contains
+    widget coordinates and sizes x(), y(), w(), and h() (STR #3385).
+    Documentation for bounds() and its internal structure was added.
+  - New method shadow(int) allows to disable the shadows of the hands
+    of Fl_Clock, Fl_Clock_Output, and derived widgets.
+  - New method Fl_Tabs::tab_align() allows to set alignment of tab labels,
+    particularly to support icons on tab labels (STR #3076).
+  - Added Fl_Surface_Device::push_current(new_surface) and
+    Fl_Surface_Device::pop_current() to set/unset the current surface
+    receiving graphics commands.
+  - New macros for easy function and method callbacks with multiple
+    type safe arguments (see FL_METHOD_CALLBACK_1 etc.) .
+
+  New Configuration Options (ABI Version)
+
+  - X11 platform: Added support for drawing text with the pango library
+    which allows to draw most scripts supported by Unicode, including CJK
+    and right-to-left scripts. FLTK now outputs PostScript that draws
+    those scripts in vectorial form. The corresponding CMake option is
+    OPTION_USE_PANGO. The corresponding configure option is --enable-pango.
+    This option is OFF by default.
+  - Configure option --enable-wayland allows to build the FLTK library for
+    the new Wayland platform while remaining compatible with X11. The
+    corresponding CMake option is OPTION_USE_WAYLAND. This option is ON by default.
+  - Configure options --enable-wayland --disable-x11 used together allow to
+    build FLTK for the Wayland backend only (no x11 backend). Under CMake, the
+    equivalent is to set both OPTION_USE_WAYLAND and OPTION_WAYLAND_ONLY.
+  - The new configure option --disable-gdiplus removes the possibility to draw
+    antialiased lines and curves on the Windows platform. The corresponding CMake
+    option is OPTION_USE_GDIPLUS.
+  - The library can be built without support for reading SVG images or writing
+    graphics in SVG format using the --disable-svg configure option
+    or turning off OPTION_USE_SVG in CMake.
+  - The library can be built without support for PostScript, thus reducing
+    its size, using the --disable-print configure option or turning off
+    OPTION_PRINT_SUPPORT in CMake. That makes classes Fl_PostScript_File_Device,
+    Fl_EPS_File_Surface and Fl_Printer (under X11 platform only) ineffective.
+  - FLTK's ABI version can be configured with 'configure' and CMake.
+    See documentation in README.abi-version.txt.
+
+  Bundled libraries
+
+  - Bundled image libraries have been upgraded to newer versions.
+    For details see README.bundled-libs.txt.
+
+  1.4.0 ABI FEATURES
+
+  - None. FLTK 1.4.0 has a new ABI, breaking 1.3.x ABI.
+
+
+  Other Improvements
+
+  - (add new items here)
+  - Reported support of macOS 14.0 "Sonoma".
+  - Added support for macOS 13.0 "Ventura".
+  - Added support for macOS 12.0 "Monterey".
+  - Added support for macOS 11.0 "Big Sur" and for building for
+    the arm64 architecture.
+  - Added support for macOS 10.15 "Catalina"
+  - Added support for macOS 10.14 "Mojave": all drawing to windows is done
+    through "layer-backed views" when the app is linked to SDK 10.14.
+  - Added support for macOS 10.13 "High Sierra".
+  - Fixed X11 Input Method window badly positioned with Fl_Text_Editor
+    widget (issue #270).
+  - Fixed X11 copy-paste and drag-and-drop target selection (issue #182).
+    This fix has been backported to 1.3.6 as well.
+  - Add optional argument to Fl_Printer::begin_job() to receive
+    a string describing the error when an error occurs.
+  - Fix Windows-specific bug when the program tries to enlarge a
+    maximized window, that would freeze the window (git issue #65).
+  - Improve X11 16-bit coordinate clipping for text (STR 2798). This
+    assumes that text is "small" WRT 16-bit coordinate space and clips
+    text if at least one of the x/y coordinates is out of bounds.
+  - Fix Fl::add_timeout() in draw() under Linux (STR 3188)
+  - Improved documentation for '@' symbols in labels (STR #2940).
+  - Fl_Roller can now be controlled via the mouse wheel (STR #3120).
+  - Tooltips hide by themselves after 12 seconds (STR #2584).
+  - Added widget visibility indicator to Fluid (STR #2669).
+  - Improved shell script support in FLUID
+  - Added Fl_Input_::append() method (STR #2953).
+  - Fix for STR#3473 (and its duplicate STR#3507) to restore configure-based
+    builds on recent Linux/Unix distributions where the freetype-config
+    command has been replaced by pkg-config.
+  - MacOS ≥ 10.10: Fl_Window::fullscreen() and fullscreen_off() no longer
+    proceed by Fl_Window::hide() + Fl_Window::show() but essentially
+    resize the window, as done on the X11+EWMH and Windows platforms.
+  - Fl_Cairo_Window constructors are now compatible with Fl_Double_Window
+    constructors - fixed missing constructors (STR #3160).
+  - The include file for platform specific functions and definitions
+    (FL/x.H) has been replaced with FL/platform.H. FL/x.H is deprecated
+    but still available for backwards compatibility (STR #3435).
+    FL/x.H will be removed in a (not yet specified) future FLTK release.
+    We recommend to change your #include statements accordingly.
+  - The Fl_Boxtype and Fl_Labeltype definitions contained enum values
+    (names) with a leading underscore (e.g. _FL_MULTI_LABEL) that had to
+    be used in this form. Now all boxtypes and labeltypes can and should
+    be used without the leading underscore. A note was added to the enum
+    documentations to make clear that the leading underscore must not be
+    used in user code, although the enum documentation still contains
+    leading underscores for technical reasons (internal use).
+  - The blocks demo program got a new keyboard shortcut (ALT+SHIFT+H) to
+    reset the user's high score. It is now slower than before in higher
+    levels, hence you can expect higher scores (due to a bug fix in the
+    timer code). You can use the '+' key to increase the level at all times.
+  - Some methods of Fl_Tabs are now virtual and/or protected for easier
+    subclassing without code duplication (STR #3211 and others).
+    To be continued...
+  - Separated Fl_Input_Choice.H and Fl_Input_Choice.cxx (STR #2750, #2752).
+  - Separated Fl_Spinner.H and Fl_Spinner.cxx (STR #2776).
+  - New method Fl_Spinner::wrap(int) allows to set wrap mode at bounds if
+    value is changed by pressing or holding one of the buttons (STR #3365).
+  - Fl_Spinner now handles Up and Down keys when the input field has
+    keyboard focus (STR #2989).
+  - Renamed test/help.cxx demo program to test/help_dialog.cxx to avoid
+    name conflict with CMake's auto-generated target 'help'.
+  - Many documentation fixes, clarifications, and enhancements.
+
+
+  Bug Fixes
+
+  - (add new items here)
+  - Fixed all Pixmaps to be '*const' (STR #3108).
+  - Fixed Fl_Text_Editor selection range after paste (STR #3248).
+  - Fixed crash for very small Fl_Color_Chooser (STR #3490).
+  - Removed all shadow lint in header files (STR #2714).
+  - Fixed pulldown menu position when at the bottom of the screen (STR #2880).
+  - Fixed missing item handling in Fl_Check_Browser (STR #3480).
+  - Fixed Delete key in Fl_Input deleting entire widgets in Fluid (STR #2841).
+  - Reorganized Fluid Template feature (STR #3336).
+  - Updated Fluid documentation and image (STR #3328).
+  - Duplicating Widget Class in Fluid no longer crashes (STR #3445).
+  - Fl_Check_Browser::add(item) now accepts NULL (STR #3498).
+  - Interface to set maximum width of spinner text field (STR #3386).
+  - Fl_Text_Display no longer wiggles (STR #2531).
+  - Fixed Help_View return value (STR #3430).
+  - Fix 'fluid.app' on case sensitive macOS (was: Fluid.app).
+  - Fix FL_PUSH event handling of Fl_Check_Browser (STR #3004).
+  - Fix a potential crash when a program exits before it opens a window
+    (Windows only, STR #3484).
+  - Fix Fl_PNG_Image error handling. An error was potentially caused
+    by error handling of the image library with setjmp/longjmp.
+  - Fix Fl_Browser background and text color parsing (STR #3376).
+  - Fix Windows CreateDC/DeleteDC mismatch (STR #3373).
+  - Fix Fl_Tabs label drawing for Fl_Window children (STR #3075).
+  - Fix line number alignment in Fl_Text_Display/Editor (STR #3363).
+  - Fix ignored buffer pre-allocation (requestedSize) in Fl_Text_Buffer.
+    See fltk.general "Fl_Text_Buffer constructor bug" on Dec 5, 2016.
+  - Fix build with configure --enable-cairo --enable-cairoext,
+    see this report in fltk.general:
+    https://groups.google.com/forum/#!topic/fltkgeneral/x80qQ6wt0s4
+
+
+  Removed Features
+
+  - Bundled IDE project files (Xcode and Visual Studio) have been
+    removed. Please use CMake to generate your IDE project files.
+    See README.CMake.txt for more information.
+  - Dropped FLTK 1.0 compatibility (macro FLTK_1_0_COMPAT). This "feature"
+    was no longer usable since FLTK 1.3, hence it can be dropped safely.
