  - screen03.sys

svn3765
  - memfiles now switched only by PRELOAD (or Alt-F8 in loader menu) option.
    os2krnl.ini presence does not turn it on.

svn3735
  - dbport=0 fixed, can be used to print debug log to screen on PCs without
    serial port

svn3728
  - release build added (os2krnlr.os4)
    This is usual release kernel with trap screen & working RIPL=ON. There is no
    internal debugger, but log to com port/kernel log still available.
    Any other features/bugs must replicate default debug build.
    On some tasks release kernel is faster up to 15%...

svn2970
  - Polling for Ctrl+C on KDB serial port is disabled in kernel by default. New
    CTRLC option has been added to os2ldr.ini to enable the polling.

svn2941
  - EOI for IRQ on slave PIC is changed to enable master PIC only when no more
    slave PIC IRQs are handled. With old way it was possible to spuriosly enable
    master PIC and to get unexpected nested IRQ handlers

svn1628
  - Add KernOpenEventSem, KernCloseEventSem, KernPostEventSem, KernResetEventSem
  - Fix and optimize IRQ routing

svn1350
  - config.sys boot editor (press Alt-E in loader menu or |||OS/2 bar)
    Editor does not change file on disk - it modify only actual boot config.sys
    copy.
  - kernel update (to make Mensys happy, but i'm think, this is a void idea ;))
    You now need the original, 104a debug kernel to install OS/4 kernel, sorry.

svn1334

  - Fixed some bugs.
  - Added some debug info for memory alloc/free.
  - Added OBJ_LOCSPECIFIC flag to DosAllocMem
  - Added index 33 to DosQuerySysInfo - get OS/4 svn revision

Initial release:
  - Fixed nvidia/VIA internal chipset trap (SMP only) so that mainboards
    containing the chipset can now work with os2apic.psd
  - Implemented a new LX compression algorithm in kernel
  - Added a PSD helper for opening/reading/closing files
  - Added the KernPrintf routine
  - Added the DosHlp_Printf routine
  - Fixed DevHlp_OpenFile to return the file size
  - Added HLT to CPUtoOffline
  - Added binary fix 104b
  - Fixed some previously undetected IBM bugs
  - Memory files for boot process
