 298 <H2> SDL 1.2.10 Release Notes </H2>
 299 <P>
 300 SDL 1.2.10 is a major release, featuring a revamp of the build system and many API improvements and bug fixes.
 301 </P>
 302 <H3> API enhancements </H3>
 303 <UL>
 304 <LI>
 305         If SDL_OpenAudio() is passed zero for the desired format
 306         fields, the following environment variables will be used
 307         to fill them in:
 308 <pre><code>
 309                 SDL_AUDIO_FREQUENCY
 310                 SDL_AUDIO_FORMAT
 311                 SDL_AUDIO_CHANNELS
 312                 SDL_AUDIO_SAMPLES
 313 </code></pre>
 314         If an environment variable is not specified, it will be set
 315         to a reasonable default value.
 316 <LI>
 317         SDL_SetVideoMode() now accepts 0 for width or height and will use
 318         the current video mode (or the desktop mode if no mode has been set.)
 319 <LI>
 320         Added current_w and current_h to the SDL_VideoInfo structure,
 321         which is set to the desktop resolution during video intialization,
 322         and then set to the current resolution when a video mode is set.
 323 <LI>
 324         SDL_GL_LoadLibrary() will load the system default OpenGL library
 325         if it is passed NULL as a parameter.
 326 <LI>
 327         Added SDL_GL_SWAP_CONTROL to wait for vsync in OpenGL applications.
 328 <LI>
 329         Added SDL_GL_ACCELERATED_VISUAL to guarantee hardware acceleration.
 330 <LI>
 331         SDL_WM_SetCaption() now officially takes UTF-8 title and icon strings, and displays international characters on supported platforms.
 332 <LI>
 333         Added SDL_GetKeyRepeat() to query the key repeat settings.
 334 <LI>
 335         Added the "dummy" audio driver, which can be used to emulate audio
 336         output without a sound card.
 337 <LI>
 338         Added SDL_config.h, with defaults for various build environments.

 346 <P>
 347         The SDL development source code is now managed with <A HREF="http://www.libsdl.org/svn.php">Subversion</A>.
 348 <P>
 349         SDL now uses the Bugzilla <A HREF="http://bugzilla.libsdl.org/">bug tracking system</A>, hosted by icculus.org.
 350 <P>
 351         SDL is licensed under version 2.1 of the GNU Lesser General Public License.
 352 <P>
 353         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.
 354 <P>
 355         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>

 362 <BLOCKQUOTE>
 363 <P>
 364         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.
 365 <P>
 366         The XiG XME extension code is now included in the X11 video driver by default.
 367 <P>
 368         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.
 369 <P>
 370         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.
 371 <P>
 372         XVidMode video modes are now sorted so they maintain the refresh rates specified in the X11 configuration file.
 373 <P>
 374         SDL windows are no longer transparent in X11 compositing systems like XGL.
 375 <P>
 376         The mouse is properly released by the X11 video driver if the fullscreen window loses focus.
 377 <P>
 378         The X11 input driver now uses XIM to handle international input.
 379 <P>
 380         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.
 381 <P>
 382         Fixed a bug preventing stereo OpenGL contexts from being selected on the X11 driver.
 383 <P>
 384         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.
 385 <P>
 386         The framebuffer console video driver now has a parser for /etc/fb.modes for improved video mode handling.
 387 <P>
 388         The framebuffer console video driver now allows asynchronous VT switching, and restores the full contents of the screen when switched back.
 389 <P>
 390         The framebuffer console now uses CTRL-ALT-FN to switch virtual terminals, to avoid collisions with application key bindings.
 391 <P>
 392         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.
 393 <P>
 394         The SVGAlib video driver now has support for banked (non-linear) video modes.
 395 <P>
 396         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.
 397 <P>
 398         Many patches have been incorporated from *BSD ports.

 404 <P>
 405         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".
 406 <P>
 407         SDL has been ported to 64-bit Windows.
 408 <P>
 409         Dmitry Yakimov contributed a GAPI video driver for Windows CE.
 410 <P>
 411         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.
 412 <P>
 413         Dialog boxes are now shown when SDL is in windowed OpenGL mode.
 414 <P>
 415         The SDL window is recreated when necessary to maintain OpenGL context attributes, when switching between windowed and fullscreen modes.
 416 <P>
 417         An SDL_VIDEORESIZE event is properly sent when the SDL window is maximized and restored.
 418 <P>
 419         Window positions are retained when switching between fullscreen and windowed modes.
 420 <P>
 421         ToUnicode() is used, when available, for improved handling of international keyboard input.
 422 <P>
 423         The PrtScrn is now treated normally with both key down and key up events.
 424 <P>
 425         Pressing ALT-F4 now delivers an SDL_QUIT event to SDL applications.
 426 <P>
 427         Joystick names are now correct for joysticks which have been unplugged and then plugged back in since booting.
 428 <P>
 429         An MCI error when playing the last track on a CD-ROM has been fixed.
 430 <P>
 431         OpenWatcom projects for building SDL have been provided by Marc Peter.

 439 <P>
 440         The X11 video driver with GLX support can be built on Mac OS X, if the X11 development SDK is installed.
 441 <P>
 442         Transitions between fullscreen resolutions and windowed mode now use a much faster asynchronous fade to hide desktop flicker.
 443 <P>
 444         Icons set with SDL_WM_SetIcon() now have the proper colors on Intel Macs.
