1.6.0 (2011-??-??):
+ * Added support for the alternate version of the Final Doom
+ executable included in some later versions of the Id Anthology.
+ This version fixed the demo loop crash that occurred with the
+ "original" Final Doom executable.
+
+ This executable can be selected on the command line with
+ -gameversion final2. It has been made the default when playing
+ with the Final Doom IWADs (the original behavior can be
+ selected with -gameversion final). (thanks Porsche Monty,
+ Enjay).

Compatibility:
* Very short sound effects are not played, to better emulate the
behavior of DMX in Vanilla Doom (thanks to Quasar for help in

-== Game exits in demo loop when playing Final Doom ==
-
-When playing with the Final Doom IWAD files (tnt.wad, plutonia.wad),
-if you leave the game at the title screen to play through the demo
-loop, it will eventually exit with the following error message:
-
- W_GetNumForName: demo4 not found!
-
-This is the same behavior as the Vanilla executables that were
-bundled with Final Doom. When Ultimate Doom was developed, a fourth
-demo was added to the demo loop, and this change was retained in the
-Final Doom version of the executable. However, the Final Doom IWADs
-do not include a fourth demo, so the game crashes.
-
-One way to work around this problem is to make the game emulate the
-original (pre-Ultimate Doom) v1.9 executable. To do this, add the
-command line argument "-gameversion 1.9" when running the game.
-However, be aware this version does have some subtle differences that
-will affect the playback of Final Doom demos (lost soul bouncing,
-teleport behavior).
