- Task-switching bug fixed! YEEE-HAA!
- Code now uses a more traditional naming/indent style
- COFFLOAD can now start the OS using VCPI (DOS with EMM386)
- DJGPP COFF kernel and DJGPP COFF user tasks are now packaged
  into a "boot bundle", which is loaded into conventional
  memory by COFFLOAD
- Improved paging. Kernel code pages are mapped read-only,
  and Cosmos no longer maps an entire 4 meg for the kernel.
  Page 0 is left unmapped, to catch NULL pointers.
- Better Makefiles
- C library (Tinylib) fixes: memcmp(), do_printf()
- Asm portions of C library converted to GCC inline asm
- 90x60 utility ported to DJGPP and underline bug fixed
- Demand-loading! Still no block devices or filesystems;
  the "load" is actually a memcpy()
- Tasks performing illegal operations are killed, and their
  memory recovered
- New syscalls: SYS_SBRK, SYS_TIME, SYS_YIELD, SYS_EXIT
- Keyboard driver now works with scancode sets 3 or 1
- Makefile option to shut off features which are not compatible
  with the Bochs PC simulator

Have fun!
