470 <H2> SDL 1.2.10 Release Notes </H2>
471 <P>
472 SDL 1.2.10 is a major release, featuring a revamp of the build system and many API improvements and bug fixes.
473 </P>
474 <H3> API enhancements </H3>
475 <UL>
476 <LI>
477 If SDL_OpenAudio() is passed zero for the desired format
478 fields, the following environment variables will be used
479 to fill them in:
480 <pre><code>
481 SDL_AUDIO_FREQUENCY
482 SDL_AUDIO_FORMAT
483 SDL_AUDIO_CHANNELS
484 SDL_AUDIO_SAMPLES
485 </code></pre>
486 If an environment variable is not specified, it will be set
487 to a reasonable default value.
488 <LI>
489 SDL_SetVideoMode() now accepts 0 for width or height and will use
490 the current video mode (or the desktop mode if no mode has been set.)
491 <LI>
492 Added current_w and current_h to the SDL_VideoInfo structure,
493 which is set to the desktop resolution during video intialization,
494 and then set to the current resolution when a video mode is set.
495 <LI>
496 SDL_GL_LoadLibrary() will load the system default OpenGL library
497 if it is passed NULL as a parameter.
498 <LI>
499 Added SDL_GL_SWAP_CONTROL to wait for vsync in OpenGL applications.
500 <LI>
501 Added SDL_GL_ACCELERATED_VISUAL to guarantee hardware acceleration.
502 <LI>
503 SDL_WM_SetCaption() now officially takes UTF-8 title and icon strings, and displays international characters on supported platforms.
504 <LI>
505 Added SDL_GetKeyRepeat() to query the key repeat settings.
506 <LI>
507 Added the "dummy" audio driver, which can be used to emulate audio
508 output without a sound card.
509 <LI>
510 Added SDL_config.h, with defaults for various build environments.

517 The SDL website now has an <A HREF="http://www.libsdl.org/rss/rss.xml">RSS feed</A>!
518 <P>
519 The SDL development source code is now managed with <A HREF="http://www.libsdl.org/svn.php">Subversion</A>.
520 <P>
521 SDL now uses the Bugzilla <A HREF="http://bugzilla.libsdl.org/">bug tracking system</A>, hosted by icculus.org.
522 <P>
523 SDL is licensed under version 2.1 of the GNU Lesser General Public License.
524 <P>
525 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.
526 <P>
527 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>

535 <P>
536 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.
537 <P>
538 The XiG XME extension code is now included in the X11 video driver by default.
539 <P>
540 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.
541 <P>
542 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.
543 <P>
544 XVidMode video modes are now sorted so they maintain the refresh rates specified in the X11 configuration file.
545 <P>
546 SDL windows are no longer transparent in X11 compositing systems like XGL.
547 <P>
548 The mouse is properly released by the X11 video driver if the fullscreen window loses focus.
549 <P>
550 The X11 input driver now uses XIM to handle international input.
551 <P>
552 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.
553 <P>
554 Fixed a bug preventing stereo OpenGL contexts from being selected on the X11 driver.
555 <P>
556 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.
557 <P>
558 The framebuffer console video driver now has a parser for /etc/fb.modes for improved video mode handling.
559 <P>
560 The framebuffer console video driver now allows asynchronous VT switching, and restores the full contents of the screen when switched back.
561 <P>
562 The framebuffer console now uses CTRL-ALT-FN to switch virtual terminals, to avoid collisions with application key bindings.
563 <P>
564 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.
565 <P>
566 The SVGAlib video driver now has support for banked (non-linear) video modes.
567 <P>
568 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.
569 <P>
570 Many patches have been incorporated from *BSD ports.

577 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".
578 <P>
579 SDL has been ported to 64-bit Windows.
580 <P>
581 Dmitry Yakimov contributed a GAPI video driver for Windows CE.
582 <P>
583 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.
584 <P>
585 Dialog boxes are now shown when SDL is in windowed OpenGL mode.
586 <P>
587 The SDL window is recreated when necessary to maintain OpenGL context attributes, when switching between windowed and fullscreen modes.
588 <P>
589 An SDL_VIDEORESIZE event is properly sent when the SDL window is maximized and restored.
590 <P>
591 Window positions are retained when switching between fullscreen and windowed modes.
