 3. History

 2006/08/15:  version 2.7
 
 þ joyGetPos added (dummy)
 
 2006/07/15:  version 2.6
 
 þ midiInReset, midiInPrepareHeader, midiInUnprepareHeader,
   midiInGetErrorTextA, midiInAddBuffer added (dummies)
 þ waveInStop added (dummy)
 þ mixerGetDevCapsA added (dummy)
 þ take into account that SB "high" DMA channel may be < 4
 
 2006/06/14:  version 2.5
 
 þ midiInStop added (dummy)
   
 2006/03/08:  version 2.4
 
 þ timeSetEvent now accepts a delay of 1 ms, previously if had to be at
   least 2 ms. Makes qemu 0.8.0 to work with hx.
 þ modified the code so it uses the DPMI virtual interrupt flag functions
   to temporarily disable interrupt. WinXP and DosEmu require to use
   these because the IF itself will not tell the truth.
 þ the previous version used undocumented DSP command FBh get status
   to be able to continue sound output even after another app has
   reprogrammed or reset the DSP. Using this feature is not recommended.
 
 2006/02/06:  version 2.3

 þ continue playing sound now checks if another app has done a SB reset.
   If yes, sound is reinitialized.
 þ WOM_OPEN/WOM_CLOSE notifcations for waveOut implemented.
 þ timeGetTime now uses GetTickCount, which has been improved to provide
   a 1 ms resolution. Previously resolution was 55 ms.
 þ timeGetDevCaps now implemented
 þ just one helper thread - if any - now created to handle all multimedia
   functions currently implemented (time, wave, midi).
 þ some midiOutXXX functions implemented. SB MPU 401 output should work now
   on SB 16 compatible cards.
 þ waveOutGetDevCapsA now implemented
 þ bugfix: waveOutGetNumDevs returned MMSYSERR_NODRIVER instead of NULL
   if no sound device was available.
 þ bugfix: if there was anything else in the BLASTER environment variable
   except Axxx, Ix, Dx, Hx, Pxxx and Tx, the scan was skipped and the 
   sound card not accepted.
   
 2006/01/22:  version 2.2
 
 þ waveOutGetPosition added (with TIME_BYTES type)
 þ waveOutPause, waveOutRestart added
 þ waveOutGetDevCapsA, waveOutGetVolume added (dummies)
 þ auxGetDevCapsA, auxGetNumDevs, auxSetVolume, auxGetVolume added (dummies)
 
 2006/01/02:  version 2.1
 
 þ mixerOpen added (dummy)
 þ wave support for SoundBlaster Pro added.
 þ midiInOpen, midiInClose, midiInStart, midiInGetNumDevs, midiInGetDevCapsA
   added (dummies)
 þ waveOutSetVolume, waveOutGetID added
 þ bugfix: waveOut window callback with wrong lParam
 þ bugfix: waveOutReset didn't dequeue buffers
 
 2005/12/20:  version 2.0
 
 þ waveOutOpen, waveOutClose, waveOutReset, waveOutWrite,
   waveOutPrepareHeader, waveOutUnprepareHeader now work
   with SoundBlaster 16 compatible device.
 þ midiOutOpen, midiOutClose, midiOutGetVolume (dummies)
 þ midiOutGetNumDevs, waveOutGetNumDevs added
 þ midiStreamPause, midiOutShortMsg added (dummies
 þ timeGetDevCaps, midiOutGetDevCapsA added (dummies)
 þ midiOutReset added (dummy)
 
 2005/12/07:  V1.2
 
 þ waveOutReset (dummy) added
 
 2005/11/24:  V1.1 
 
 þ midiXXX functions (dummy) added
 
 2005/10/10:  version 1.0
