<h2><b>New in Release 1.4</b></h2>
<p>FIXME - add feature list</p>
<!--
<ul>
<li>Improved TIA sound system so that games with digitized audio work</li>
<li>Added saving and loading of game state to the core; X11, SDL, and DOS
versions current support saving and loading game state</li>
<li>Added support for F4 bankswitching method</li>
<li>Pitfall II DPC sound emulation completed</li>
<li>Fixed a bug which caused the difficulty switches to operate backwards</li>
<li>Changed DPC auto-detection to use file size so that Pitfall II mods work</li>
<li>Modified RIOT timer emulation so that startup values are random</li>
<li>Added 3F bankswitching auto-detection routine so that homebrews and
demos work without a stella.pro entry</li>
<li>Updated the TIA message boxes so they look a little nicer</li>
<li>Latest stella.pro file included in distribution</li>
<li>Added some <b>developer</b> options to the core, and the ability to change
game width, height, xstart, ystart, etc. while the emulation is running. Added
ability to switch between NTSC and PAL at runtime, and the ability to save the
current properties to a file or to merge the changes into the stella.pro file;
X11 and SDL versions supported for now</li>
<li>Added save/load state ability to the core; X11 and SDL versions supported for now</li>
<li>External sound server for the X11 and SDL versions no longer required, as all
sound code is now integrated into the core</li>
<li>Changed the locations of the users' config files for the X11 and SDL versions; the users'
stellarc file is now located in "<i>$HOME/.stella/stellarc</i>", state files
are located in "<i>$HOME/.stella/state/</i>" and the stella.pro file is located
in "<i>$HOME/.stella/stella.pro</i>"
<li>Changed the way options are supplied on the commandline. Now all commandline
options take <b>exactly</b> the same arguments as in the INI file</li>
<li>Added "<i>-accurate</i>" command line option to choose between accurate
(CPU-intensive) timing or less accurate (CPU-friendly) timing to X11 and SDL
versions. This is the final version of what was considered experimental timing code
in Stella 1.2</li>
<li>Added "<i>-sound</i>" command line option to choose which sound backend to use
(alsa, oss, sdl) with the X11 and SDL versions</li>
<li>Added the following <b>developer</b> command line options to the X11 and SDL
versions, which are only activated in <b>developer</b> builds:
<ul>
<li><i>-Dformat</i></li>
<li><i>-Dwidth</i></li>
<li><i>-Dheight</i></li>
<li><i>-Dxstart</i></li>
<li><i>-Dystart</i></li>
<li><i>-Dmerge</i></li>
</ul></li>
<li>Fixed window resize bug in the X11 port</li>
<li>Added "<i>-nosound</i>" command line option to the DOS port to disable audio</li>
<li>DOS port supports a "<i>-vsync</i>" option to synchronize emulation with the
video blank of the video card</li>
<li>Changed VGA code in the DOS port to use a 60Hz 320x200 and a 60Hz
320x240 graphics mode</li>
<li>DOS port has been updated to run better under Windows NT, 2000, and XP.
There are still issues with the sound, however, it is usable.</li>
<li>DOS port is using a new Sound Blaster driver created by Matt Conte which
supports auto-detection of sound cards.</li>
<li>DOS port supports a STELLA_HOME environment variable that defines
the location of config files.</li>
<li>In the DOS port the stella.pro file is searched for first in the
current working director and then in the <i>%STELLA_HOME%</i> directory
<li>In the DOS port the ROM image is searched for first using the
specified path, then in <i>%STELLA_HOME%/ROMS</i>, and finally
in <i>%STELLA_HOME%</i></li>
<li>Codebase ported to SDL. The DOS and X11 ports have been discontinued.</li>
<li>Sound code ported to SDL. For the Linux versions, ALSA and OSS sound
support has been discontinued.</li>
<li>The Linux, MacOSX and Windows ports are now based on the same codebase and
are actively maintained. That means simultaneous (and hopefully
more frequent) releases.</li>
<li>A new Windows port has been created, with the GUI based on StellaX.
This is the first new release for Windows since Stella 1.2.</li>
<li>A new Mac OSX port has been created by Mark Grebe. This is the first new
release for Mac OSX since Stella 1.2.</li>
<li>Added OpenGL rendering support.</li>
<li>Added more refined in-game GUI.</li>
<li>Added event remapping. Emulation keys can now be remapped to the keyboard
or up to 4 joysticks.</li>
<li>Added native Stelladaptor support. Joysticks, paddles, and driving controllers
have been tested.</li>
<li>Digital sound support (used in games like Quadrun and Pitfall2) has been
greatly improved. Sound generation is now more tightly synchronized with
video updates.</li>
<li>Added support for UA Limited style bankswitching (Funky Fish and Pleiades).</li>
<li>Switched to using <i>high compatibility M6502 mode</i> by default.
<li>The meaning of the "<i>-sound</i>" command line option has been changed.
This option now accepts either 'true' or 'false (1 or 0) to enable/disable
sound.</li>
<li>Changed sound mixer functionality. The system volume/mixer settings will
never be changed; volume changes in Stella will only affect the emulation
itself.</li>
<li>Added "<i>-video</i>" command line option. This option accepts either 'soft'
or 'gl', to use software/OpenGL rendering.</li>
<li>Added "<i>-gl_filter</i>" command line option. This option accepts either
'nearest' or 'linear', to use GL_NEAREST or GL_LINEAR filtering.</li>
<li>Added "<i>-gl_aspect</i>" command line option. This option accepts a decimal
value specifying how much to scale the width of the emulation image (useful
for giving an authentic 'square-looking' 4:3 mode).</li>
<li>Added "<i>-fragsize</i>" command line option. This option accepts the
size to use for sound fragments. Linux/MacOSX works well with 512,
Windows seems to need 2048. This value must be a power of two.</li>
<li>Modified "<i>-volume</i>" command line option. If you specify '-1',
Stella will use the system volume.</li>
<li>Renamed the "<i>-pro</i>" command line option to "<i>-altpro</i>".</li>
<li>Renamed the "<i>-fps</i>" command line option to "<i>-framerate</i>".</li>
<li>Removed the "<i>-center</i>" command line option. Stella now automatically
centers the window when possible.</li>
<li>Removed the "<i>-paddle real</i>" command line option, since it never really
worked correctly (and Stelladaptor support adds that functionality
anyway).</li>
<li>Removed all command line options relating to the X11 port
(owncmap, display).</li>
</ul>
