NitrOS-9 V3.2.8

• Basic09 and supporting modules are now included in the NitrOS-9 distribution.
• A bug in os9gen which caused it to create fragmented boot files by default
  has been fixed. os9gen defaults to creating non-fragmented boot files, and
  the -e option must be used to create fragmented boot files.
• The Init module has been extended to include the version string that was
  formerly in the Sysgo module. Sysgo has been modified to print this string
  from the Init module.

Level 2 Only:

• Device windows W8-W15 have been added to the distribution.
• A bug which caused the system to crash during boot if grfdrv wasn't
  in the CMDS directory has been fixed.

NitrOS-9 V3.2.6

• /D2 descriptor now part of standard boot file.

Level 1 Only:

• RBF now supports the SS.FDInf GetStt call.

NitrOS-9 V3.2.5

• rb1773 now properly saves/restores the system's NMI vector, also updated to
  go into 0.89MHz mode when formatting to get around a problem with some
  CoCo 3's crashing during format.
• An issue with formatting 3.5" 720K disks has been resolved.

Level 1 Only:

• Two new modules: CO51.io and term51.dt are available for 51x24 text
  support on a graphics screen.
• CO80.io and term80.dt are no longer included in the repository, as
  there is no known supported hardware for these modules.

NitrOS-9 V3.2.4

• Fixed several problems/mistakes in the V3.2.3 release.

NitrOS-9 V3.2.3

• format has been enhanced to show more information about the disk being formatted.
• dirm has been removed from the commands list.

Level 2 Only:

• grfint.io now exists and can be used to replace windint.io in boot files where Multi-Vue windowing functionality is not needed, in order to save system RAM.
• Changes in SCF and GrfDrv have resulted in faster text screen performance under NitrOS-9/6809 Level 2.
• A bug related to system memory allocation and DAT blocks has been fixed in Krn.
• IOMan now properly unlinks a device descriptor at I$Detach time.
• The pmap command has several bug fixes.

• KeyDrv and SndDrv have been renamed to keydrv_cc3.sb and snddrv_cc3.sb,
  and all relevant bootlist files have been changed.
