Woof! 4.0.0
-----------
- The -fast and -respawn options are now properly reloaded from
  savegames.
- PNG screenshots are now exact reproductions# of the actual
  game# screen.

- A workaround for the SDL 2.0.14 Alt-Tab bug on Windows has been
  introduced (@rfomin).
- A woof-midiproc.exe has been ported over from Crispy Doom, allowing to
  set SFX and music volume separately on Windows (@rfomin).
- The SPECHITS overflow emulation has been ported over from Chocolate
  Doom / PrBoom+, allowing for some more obscure Vanilla demos to keep
  sync.
- The "IDKFA" cheat string has been externalized, allowing it to be
  replaced by DEHACKED.
- The widescreen rendering mode has been ported over from Crispy Doom
  with proper support for the widescreen assets found e.g. in the Unity
  version of Doom (@rfomin).
- MIDI playback on big-endian systems has been fixed (@BeWorld2018).

  conflicts with high-resolution textures (@rfomin).
- The option to show the "A secret is revealed!" message has been added
  (@rfomin).
- The window geometry and display index settings are now saved across
  restarts (@rfomin).
- The -pistolstart command line option has been added (@rfomin).
- Support for 16-bit WAV sound lumps has been added (@rfomin).
- Support for the "MUSINFO" lump has been added (@rfomin).
- Demo compatibility with Boom 2.02 has been vastly improved:
- MBF codepointers are now disabled during Boom demo playback (@rfomin).
- The P_FindShortestTextureAround() function has been fixed (@rfomin).
- Boom's friction code has been restored (@rfomin).
- Boom's BLOCKMAP generation code has been integrated (@rfomin).
- Sprite lumps smaller than 8 bytes are now ignored (@rfomin).
- Empty music lumps (i.e. with zero length) are now properly handled
  (@rfomin).
- The weapon attack alignment implementation has been brought in line
  with Crispy Doom.
- The "no fog on spawn west" Vanilla Doom bug is now properly emulated
  (@rfomin).
- Switches definitions referencing unknown texture names are now ignored
  instead of exiting (@rfomin).
- A crash has been fixed when reading out joystick button states.
- Endianess issues with positioning the status bar patch, drawing the
  bunny scroll screen and fullscreen patches have been fixed.

Unfortunately, some of these changes made it necessary to change the
savegame format which is now incompatible to previous releases.
