-------------------------------- 0.57 -----------------------------------

- Fix compilation for Coldfire CPU.
- Fix compilation for gcc 4.
- Add SDL YUV Overlay support.

-------------------------------- 0.56 -----------------------------------

- README: list supported game data files.
- Add -iwad /path/to/gamefile.wad parameter.

-------------------------------- 0.55 -----------------------------------

- Convert audio if 16bits stereo not available.

-------------------------------- 0.54 -----------------------------------

- Added low/high detail message.
- Atari: more rendering optimizations, special 060 routine.
- Fixed weapon drawing in low detail.
- Fixed crash in audio on exit.
- Unrolled 4x rendering loops, a bit faster.
- Rewritten CD music player for SDL.

-------------------------------- 0.52 -----------------------------------

- Disable checksum on networked packets, allow networking with machines with
  different endianness.

-------------------------------- 0.51 -----------------------------------

- Document used environment variables.
- SDL_mixer enable/disable check in configure was wrong.
- Fixed uninitialized bottom array for visplane structure, causing R_MapPlane 
  errors.

-------------------------------- 0.50 -----------------------------------

- Response file readable as '-response <filename>' also with legacy '@filename'
  parameter. '@' character was not usable in standard Atari desktop dialog
  box for command-line.
- Atari: Reserve 256KB instead of 128KB for audio/video buffers as default.

-------------------------------- 0.49 -----------------------------------

- Configuration file and saved games now loaded/saved to $HOME/.hexen directory
  if $HOME is defined.
- Open first available joystick, and print its name. Can also select which
  joystick to use (new 'num_joystick' value in heretic config file).
- Print audio device informations when opening.
- Atari: m68k asm for audio mixing routine.

-------------------------------- 0.46 -----------------------------------

- Z_Malloc() don't align memory blocks on 4 bytes boundary like Doom, fixed.
- Many endianness stuff was removed in source, and crashes on big endian
  systems, fixed.

-------------------------------- 0.45 -----------------------------------

- Can compile with/without SDL_mixer also under Linux.
- Atari: display memory left in ST-Ram for audio/video subsystems.

-------------------------------- 0.44 -----------------------------------

- Texturing on floors/ceilings can be switched off.

-------------------------------- 0.43 -----------------------------------

- Don't call sound related functions when audio disabled.
- Check for shareware/complete version, 4/8 players version.
- Fixed missing endianness stuff.

-------------------------------- 0.42 -----------------------------------

- Add music replay using Timidity and SDL_mixer.
  (timidity-rwops.diff (in doc subdir) patch must be applied to SDL_mixer)
- Fixed P_FindNextHighestFloor() for Heretic E3M8, from Doom legacy.
- Atari: Force memory allocation to FastRam if available.

-------------------------------- 0.41 -----------------------------------

- Emulate Pause key with Alt+P.
- Does not create shadow buffer of good size.
- Fixed analog joystick usage.
- Fixes for double buffered screen.
- Wait end of rendering to resize screen.

-------------------------------- 0.40 -----------------------------------

- Throw nearly everything to the bin, restart from the original sources.
- Only use SDL for audio/video/input.
- Dynamic resize of screen possible.
- Many memory leaks fixed using Valgrind.

-------------------------------- 0.24 -----------------------------------

- Modified to be cross-compilable for target m68k-atari-mint
  Just edit the makefile and put cross=y. Some other adjustments may be
  necessary (CROSSBINDIR_IS_y value is the path to cross-compilation tools).
  The new Atari executable is now built with gcc-2.8.1 .

- Atari version:
  Added network support (TCP/IP via MintNet), not tested

-------------------------------- 0.23 -----------------------------------

- Demo version was not detected ("SKY1 not found" bug), corrected

- Atari version :
	Bug in 8 bits mode, corrected

-------------------------------- 0.22 -----------------------------------

- Linux version:
	Svgalib:
	  '-zoomscreen'	for fullscreen mode
	  '-videomode <n>' to choose a video mode
	X11:
	  added program name in window title.
	  now window resize works with the zoom routine.

- Atari version:
	Xbios
	  '-zoomscreen'	for fullscreen mode
	  '-videomode <n>' to choose a video mode on Falcon.
	Vdi:
	  '-zoomscreen'	for fullscreen mode
	  '-novavdi' to force 15 bits in 16 bits mode
	  modified by Xavier Joubert:
	    - save/restore palette in 256 colours mode.
	    - black border around displayed zone. 
	    - test if AES is present or not.	

- Separated string version in ./src/i_version.c
- Added zoom routine
- Added 32 bits support
- Tics are calculated now after complete redraw of screen:
  So now, the time taken to do the final display (copy,double buffer,zoom) is
  taken into account.

- Dynamic system routines
  '-sound','-video','-music','-keyboard','-joystick,'-joypad','-mouse'
  can select your preferred routine. Missing features on your system are
  automatically set 'off'. Now you can easily add new routines.

  Atari version:
	-keyboard <param>	param =	ikbd,bios,off
	-mouse <param>		param = ikbd,off
	-joystick <param>	param = ikbd,off
	-joypad <param>		param = on,off
	-sound <param>		param = dma8,off
	-video <param>		param = xbios,vdi,off

	ikbd:		Ikbd-6301 interrupt routines for Atari Falcon/TT.
	bios:		Bios/Gemdos keyboard routine for all Atari.
	dma8:		Timer A sound interrupt routine for Atari Falcon/TT.
	joypad on:	Use joypad ports on Atari Falcon.
	xbios:		Xbios display on Atari Falcon/TT.
	vdi:		VDI display for all Atari and clones.
			Use '-nofastblit' to allocate VDI buffers in ST-Ram
			instead of Fast-Ram.

  Linux version:
	-keyboard <param>	param =	svgalib,x11,off
	-mouse <param>		param =	svgalib,x11,off
	-sound <param>		param = audio,off
	-video <param>		param = svgalib,x11,off

	svgalib:	Svgalib routines for Linux/x86
	x11:		X11 routines for Linux
	audio:		Linux audio device routine

-------------------------------- 0.15 -----------------------------------

- Corrected 24bits rendering routine
- Added low detail mode
- Corrected bug in sound routine
- Moved assembly m68k sources to ./src/m68k
- Corrected BIGENDIAN missing conversions in ./src/p_acs.c

Svgalib version:
  - Use '-video-8' to switch to 320x240x8 bits double buffer mode

Atari version:
  - Changed '-falcon8' to '-video-8'
  - Added VDI display routine from Johan Klockhars
    Use '-pixelinv' to use byte reversed pixels in TrueColour.
  - Added DMA sound  
  - Corrected conflict between sound and keyboard routine

-------------------------------- 0.12 -----------------------------------

Corrected a refresh bug in double buffer mode.

Atari version:
  - New keyboard routine: you can use mouse,joystick,joypad (port 0)
    Delete old config files !

-------------------------------- 0.11 -----------------------------------

- Corrected a bug in the save path

Atari version:
  - Falcon version can use 8 bitplanes mode : '-falcon8' switch
  - Should now work on Atari TT in 320x480x8 bits mode (not tested)

-------------------------------- 0.10 -----------------------------------

- Border in not fullscreen mode correctly refreshed in double buffer

Svgalib version:
  - Now can double-buffer in 320x240 mode X style, if compiled for.

-------------------------------- 0.08 -----------------------------------

Linux/x86/PC and [Mint,Tos]/m68k/F30 common sources 
  - Back to C only for this version
  - Some ASM routs for Atari version
  - '-devparm' displays number of tics
  - If $HOME is defined, configuration and games are saved in
    "$HOME/.hexen/" else in "./"

-------------------------------- 0.02 -----------------------------------

- Display done in 8,15,16,24 bits modes.

Linux version :
