   208 <H2> SDL 1.2.10 Release Notes </H2>
   209 <P>
   210 SDL 1.2.10 is a major release, featuring a revamp of the build system and many API improvements and bug fixes.
   211 </P>
   212 <H3> API enhancements </H3>
   213 <UL>
   214 <LI>
   215 	If SDL_OpenAudio() is passed zero for the desired format
   216 	fields, the following environment variables will be used
   217 	to fill them in:
   218 <pre><code>
   219 		SDL_AUDIO_FREQUENCY
   220 		SDL_AUDIO_FORMAT
   221 		SDL_AUDIO_CHANNELS
   222 		SDL_AUDIO_SAMPLES
   223 </code></pre>
   224 	If an environment variable is not specified, it will be set
   225 	to a reasonable default value.
   226 <LI>
   227 	SDL_SetVideoMode() now accepts 0 for width or height and will use
   228 	the current video mode (or the desktop mode if no mode has been set.)
   229 <LI>
   230 	Added current_w and current_h to the SDL_VideoInfo structure,
   231 	which is set to the desktop resolution during video intialization,
   232 	and then set to the current resolution when a video mode is set.
   233 <LI>
   234 	SDL_GL_LoadLibrary() will load the system default OpenGL library
   235 	if it is passed NULL as a parameter.
   236 <LI>
   237 	Added SDL_GL_SWAP_CONTROL to wait for vsync in OpenGL applications.
   238 <LI>
   239 	Added SDL_GL_ACCELERATED_VISUAL to guarantee hardware acceleration.
   240 <LI>
   241 	SDL_WM_SetCaption() now officially takes UTF-8 title and icon strings, and displays international characters on supported platforms.
   242 <LI>
   243 	Added SDL_GetKeyRepeat() to query the key repeat settings.
   244 <LI>
   245 	Added the "dummy" audio driver, which can be used to emulate audio
   246 	output without a sound card.
   247 <LI>
   248 	Added SDL_config.h, with defaults for various build environments.
   249 </UL>

   251 <H3> General Notes </H3>

   253 <BLOCKQUOTE>
   254 <P>
   255 	The SDL website now has an <A HREF="http://www.libsdl.org/rss/rss.xml">RSS feed</A>!
   256 <P>
   257 	The SDL development source code is now managed with <A HREF="http://www.libsdl.org/svn.php">Subversion</A>.
   258 <P>
   259 	SDL now uses the Bugzilla <A HREF="http://bugzilla.libsdl.org/">bug tracking system</A>, hosted by icculus.org.
   260 <P>
   261 	SDL is licensed under version 2.1 of the GNU Lesser General Public License.
   262 <P>
   263 	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.
   264 <P>
   265 	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>
   266 <P>
   267 	Alex Volkov contributed highly optimized RGB <-> RGBA blitters.

   271 
   272 <BLOCKQUOTE>
   273 <P>
   274 	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.
   275 <P>
   276 	The XiG XME extension code is now included in the X11 video driver by default.
   277 <P>
   278 	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.
   279 <P>
   280 	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.
   281 <P>
   282 	XVidMode video modes are now sorted so they maintain the refresh rates specified in the X11 configuration file.
   283 <P>
   284 	SDL windows are no longer transparent in X11 compositing systems like XGL.
   285 <P>
   286 	The mouse is properly released by the X11 video driver if the fullscreen window loses focus.
   287 <P>
   288 	The X11 input driver now uses XIM to handle international input.
   289 <P>
   290 	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.
   291 <P>
   292 	Fixed a bug preventing stereo OpenGL contexts from being selected on the X11 driver.
   293 <P>
   294 	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.
   295 <P>
   296 	The framebuffer console video driver now has a parser for /etc/fb.modes for improved video mode handling.
   297 <P>
   298 	The framebuffer console video driver now allows asynchronous VT switching, and restores the full contents of the screen when switched back.
   299 <P>
   300 	The framebuffer console now uses CTRL-ALT-FN to switch virtual terminals, to avoid collisions with application key bindings.
   301 <P>
   302 	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.
   303 <P>
   304 	The SVGAlib video driver now has support for banked (non-linear) video modes.
   305 <P>
   306 	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.
   307 <P>
   308 	Many patches have been incorporated from *BSD ports.

   311 <H3> Windows Notes </H3>
   312 
   313 <BLOCKQUOTE>
   314 <P>
   315 	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".
   316 <P>
   317 	SDL has been ported to 64-bit Windows.
   318 <P>
   319 	Dmitry Yakimov contributed a GAPI video driver for Windows CE.
   320 <P>
   321 	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.
   322 <P>
   323 	Dialog boxes are now shown when SDL is in windowed OpenGL mode.
   324 <P>
   325 	The SDL window is recreated when necessary to maintain OpenGL context attributes, when switching between windowed and fullscreen modes.
   326 <P>
   327 	An SDL_VIDEORESIZE event is properly sent when the SDL window is maximized and restored.
   328 <P>
   329 	Window positions are retained when switching between fullscreen and windowed modes.
   330 <P>
   331 	ToUnicode() is used, when available, for improved handling of international keyboard input.
   332 <P>
   333 	The PrtScrn is now treated normally with both key down and key up events.
   334 <P>
   335 	Pressing ALT-F4 now delivers an SDL_QUIT event to SDL applications.
   336 <P>
   337 	Joystick names are now correct for joysticks which have been unplugged and then plugged back in since booting.
   338 <P>
   339 	An MCI error when playing the last track on a CD-ROM has been fixed.
   340 <P>
   341 	OpenWatcom projects for building SDL have been provided by Marc Peter.

   346 <BLOCKQUOTE>
   347 <P>
   348 	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.
   349 <P>
   350 	The X11 video driver with GLX support can be built on Mac OS X, if the X11 development SDK is installed.
   351 <P>
   352 	Transitions between fullscreen resolutions and windowed mode now use a much faster asynchronous fade to hide desktop flicker.
   353 <P>
   354 	Icons set with SDL_WM_SetIcon() now have the proper colors on Intel Macs.
