OS-9 Level Two V3.01.01:
- The cc3disk module has been folded with the NitrOS-9 Level 2 version and
  as a result has changed in size.
- A bug in IOMan which affected any driver wanting to access the port
  address of its hardware while in its INIT routine has been fixed.
- The montype command had a bug-fix and now shows the current monitor type if
  no parameters are given.  Also, the montype.hp file has been updated.
- The LogBook file in the SYS directory has been removed.
- A bug in the cputype command that caused crashing on a 6809 system
  has been fixed.

OS-9 Level Two V3.01.00:
- New common version among all releases of OS-9 for the CoCo
- Many commands have been updated and optimized:
   o For size reasons, command help information is no longer embedded in the
     utilites, but is instead available through the helpmsg file in /DD/SYS
   o date, dir, mdir, procs and verify now require a dash (-) before options
   o format now has a cluster option and now shows the correct number of
     good sectors on large sector devices
   o Numerous commands have been optimized for size
   o cmp, error, help and touch have been rewritten in assembly for size
   o copy has been enhanced to include OS-9/68K-like features
- VDGInt has been back-ported to OS-9 Level Two from NitrOS-9.  The
  vdgint.io module contains both CoCo 1/2 AND CoCo 3 graphics code.
  The vdgint_small.io module only contains CoCo 3 graphics code.
- CC3Go has been moved back into the root directory from the CMDS directory.
  This keeps ROM-based users and those who want cc3go in their bootfile from
  having to change the init module, which referenced CMDS/cc3go.
- CC3Go once again references /H0 and /H0/CMDS as paths that it tries to
  chd/chx to upon startup.  This allows for those with floppy boots who
  want to point /DD at their floppy to continue to do so.  Also, if the
  forking of 'shell startup' fails due to lack of a shell file, then
  CC3Go will now try to fork AutoEx instead of jumping to the crash routine.
- Several bugs that crept into IOMan during the last release have been fixed.

OS-9 Level Two V2.01.00 Beta2:
- Defs files now have properly terminated lines and 'pag' is now emitted
  as a comment.
- SCF, Rammer and PipeMan are now made from the NitrOS-9 version source base,
  bringing in new improvements and features from that platform.
- Clock and Clock2 are now unifed once again and are built from the same source
  base as the clocks from NitrOS-9.
- The printer driver is now for the CoCo 3 serial port.  In the previous
  release, it was mistakenly made for the Disto parallel port.
- ASM now assembles 6309 op-codes.
- Window descriptors now have proper initialization count.
- The following modules have been back-ported from NitrOS-9 in order to
  unify the code base and bring non-6309 specific features to OS-9 Level Two:
- The debug program is now part of the CMDS package.
- With the inclusion of NitrOS-9's SCF, a bug which crashed the system when
  typing CTRL-E or CTRL-C while using shellplus has been fixed.
