539 <H2> SDL 1.2.10 Release Notes </H2>
541 SDL 1.2.10 is a major release, featuring a revamp of the build system and many API improvements and bug fixes.
543 <H3> API enhancements </H3>
546 If SDL_OpenAudio() is passed zero for the desired format
547 fields, the following environment variables will be used
555 If an environment variable is not specified, it will be set
556 to a reasonable default value.
558 SDL_SetVideoMode() now accepts 0 for width or height and will use
559 the current video mode (or the desktop mode if no mode has been set.)
561 Added current_w and current_h to the SDL_VideoInfo structure,
562 which is set to the desktop resolution during video intialization,
563 and then set to the current resolution when a video mode is set.
565 SDL_GL_LoadLibrary() will load the system default OpenGL library
566 if it is passed NULL as a parameter.
568 Added SDL_GL_SWAP_CONTROL to wait for vsync in OpenGL applications.
570 Added SDL_GL_ACCELERATED_VISUAL to guarantee hardware acceleration.
572 SDL_WM_SetCaption() now officially takes UTF-8 title and icon strings, and displays international characters on supported platforms.
574 Added SDL_GetKeyRepeat() to query the key repeat settings.
576 Added the "dummy" audio driver, which can be used to emulate audio
577 output without a sound card.
579 Added SDL_config.h, with defaults for various build environments.
582 <H3> General Notes </H3>
586 The SDL website now has an <A HREF="http://www.libsdl.org/rss/rss.xml">RSS feed</A>!
588 The SDL development source code is now managed with <A HREF="http://www.libsdl.org/svn.php">Subversion</A>.
590 SDL now uses the Bugzilla <A HREF="http://bugzilla.libsdl.org/">bug tracking system</A>, hosted by icculus.org.
592 SDL is licensed under version 2.1 of the GNU Lesser General Public License.
594 The entire build system has been revamped to make it much more portable, including versions of C library functions to make it possible to run SDL on a minimal embedded environment. See README.Porting in the SDL source distribution for information on how to port SDL to a new platform.
596 SDL_opengl.h has been updated with the latest glext.h from <A HREF="http://oss.sgi.com/projects/ogl-sample/registry/">http://oss.sgi.com/projects/ogl-sample/registry/</A>
598 Alex Volkov contributed highly optimized RGB <-> RGBA blitters.
601 <H3> Unix Notes </H3>
605 The X11 libraries are dynamically loaded at runtime by default. This allows the distributed version of SDL to run on systems without X11 libraries installed.
607 The XiG XME extension code is now included in the X11 video driver by default.
609 XRandR support for video mode switching has been added to the X11 driver, but is disabled because of undesired interactions with window managers. You can enable this by setting the environment variable SDL_VIDEO_X11_XRANDR to 1.
611 Xinerama multi-head displays are properly handled now, and the SDL_VIDEO_FULLSCREEN_HEAD environment variable can be used to select the screen used for fullscreen video modes. Note that changing the video modes only works on screen 0.
613 XVidMode video modes are now sorted so they maintain the refresh rates specified in the X11 configuration file.
615 SDL windows are no longer transparent in X11 compositing systems like XGL.
617 The mouse is properly released by the X11 video driver if the fullscreen window loses focus.
619 The X11 input driver now uses XIM to handle international input.
621 The screensaver and DPMS monitor blanking are disabled while SDL games are running under the X11 and DGA video drivers. This behavior will be formalized and selectable in SDL 1.3.
623 Fixed a bug preventing stereo OpenGL contexts from being selected on the X11 driver.
625 The DGA video driver now waits for pending blits involving surfaces before they are freed. This prevents display oddities when using SDL_DisplayFormat() to convert many images.
627 The framebuffer console video driver now has a parser for /etc/fb.modes for improved video mode handling.
629 The framebuffer console video driver now allows asynchronous VT switching, and restores the full contents of the screen when switched back.
631 The framebuffer console now uses CTRL-ALT-FN to switch virtual terminals, to avoid collisions with application key bindings.
633 The framebuffer console input driver correctly sets IMPS/2 mode for wheel mice. It also properly detects when gpm is in IMPS/2 protocol mode, or passing raw protocol from an IMPS/2 mouse.
635 The SVGAlib video driver now has support for banked (non-linear) video modes.
637 A video driver for OpenBSD on the Sharp Zaurus has been contributed by Staffan Ulfberg. See the file README.wscons in the SDL source distribution for details.
639 Many patches have been incorporated from *BSD ports.
642 <H3> Windows Notes </H3>
646 The "windib" video driver is the default now, to prevent problems with certain laptops, 64-bit Windows, and Windows Vista. The DirectX driver is still available, and can be selected by setting the environment variable SDL_VIDEODRIVER to "directx".
648 SDL has been ported to 64-bit Windows.
650 Dmitry Yakimov contributed a GAPI video driver for Windows CE.
652 The default fullscreen refresh rate has been increased to match the desktop refresh rate, when using equivalent resolutions. A full API for querying and selecting refresh rates is planned for SDL 1.3.
654 Dialog boxes are now shown when SDL is in windowed OpenGL mode.
656 The SDL window is recreated when necessary to maintain OpenGL context attributes, when switching between windowed and fullscreen modes.
658 An SDL_VIDEORESIZE event is properly sent when the SDL window is maximized and restored.
660 Window positions are retained when switching between fullscreen and windowed modes.
662 ToUnicode() is used, when available, for improved handling of international keyboard input.
664 The PrtScrn is now treated normally with both key down and key up events.
666 Pressing ALT-F4 now delivers an SDL_QUIT event to SDL applications.
668 Joystick names are now correct for joysticks which have been unplugged and then plugged back in since booting.
670 An MCI error when playing the last track on a CD-ROM has been fixed.
672 OpenWatcom projects for building SDL have been provided by Marc Peter.
675 <H3> Mac OS X Notes </H3>
679 SDL now supports building Universal binaries, both through Xcode projects and when using configure/make. See README.MacOSX in the SDL source archive for details.
681 The X11 video driver with GLX support can be built on Mac OS X, if the X11 development SDK is installed.
683 Transitions between fullscreen resolutions and windowed mode now use a much faster asynchronous fade to hide desktop flicker.
685 Icons set with SDL_WM_SetIcon() now have the proper colors on Intel Macs.
688 <H3> OS/2 Notes </H3>
692 Projects for building SDL on OS/2 with OpenWatcom have been contributed by Doodle. See the file README.OS2 in the SDL source distribution for details.
