Here is the short ChangeLog:

• Fixed lots of possible crashes in the IT, XM, S3M, STM, STX, AMF, IMF,
  GDM and MED module loaders.
• Fixed a possible endless loop in the IT loader with malformed files.
• Fixed signed integer overflow leading to crashes in the sample loader.
• Fixed a possible crash in MMCMP depacker with malformed files.
• Fixed the broken fixed-line comment reader which might possibly lead
  to crashes, and also badly translated several song messages. The new
  code is adapted from libopenmpt.
• Support for building the Windows version using Open Watcom compiler.
• A few minor OS/2 fixes.
• CMake updates.
• Other minor fixes/tidy-ups.

Thanks to:
- Lionel Debroux, for providing fuzz files which helped finding defects.
- Johannes Schultz (sagamusix), for allowing us to use a piece of code
from libopenmpt.
