+Changes since 2.22:
+o  Use 16 bit block pointers for file systems > 256 blocks, not >= 256
+o  Translate CP/M file name character '/' to ',' for the host and back
+o  dirblks in Kaypro format fixed
+o  Misc fixes for directory listing
+o  Added bootsec diskdefs option
+o  Check Device_close return value
+o  Check for too small block number when reading file data
+o  Replaced obsolete macros in configure.in
+o  Cygwin/Windows support did not build any more and likely not for quite
+   some time, so it was removed.
+Changes since 2.21:
+o  Refactored curses terminal calls into own module
+o  Many autoconf changes with the hope to improve portability and
+   likely just breaking things
+o  New diskdef for HP200
+o  Added dirblks to allow reserving blocks after the directory
+   as used by Kaypro
+o  Fixed user number output for cpmls -d
+o  Added option -u to show all CP/M file names in uppercase
 Changes since 2.20:
@@ Zeile 112: / Zeile 143: @@
 o  Check for invalid block size
 o  Output line number for diskdefs errors
+o  Correctly output create or access time for CP/M 3 in cpmls
+o  Spectravideo SVI-728 diskdef added
+o  $DESTDIR support
+o  Correctly handle empty files
+o  Fix block allocation for large directories.
+o  Fix time stamp conversion
+o  Allow user number 16-31 for CP/M 2.2
+o  Intel MDS/22 formats added
