CDF Changes Log

V2.0.0   11-Feb-91  Initial release of CDF V2.0.
V2.1.0    7-Jun-91  Initial release of CDF V2.1.
V2.1.1   25-Jun-91  Many changes/enhancements/fixes.
		     1. SkeletonTable now generates *.skt and *.nrv files
			instead of *.skeleton_table and *.nrv_data files.
			CDFskeleton first looks for a *.skt file.  If not
			found, it then looks for a *.skeleton_table.
		     2. CDF_EPOCH was added as a data type.  When reading
			CDFs created with previous releases (V2.1.0 and
			older), CDF_EPOCH will be returned as the data type
			when that was the intention.
		     3. The command line syntax for the toolkit programs
			was modified for more flexibility.  Qualifiers,
			options, and parameters are now specified in the
			style of the host operating system.
		     4. File names were changed to allow portability in the
			future.
V2.1.2    9-Aug-91  More changes but getting closer to the "official" release
		    of V2.1 (waiting mainly for the documentation).
		     1. New toolkit programs/utilities - CDFwalk, CDFdir.
		     2. UNIX systems now use VIO.
		     3. Toolkit programs now exit with "status".
		     4. Added message logging qualifier to skeleton toolkit
			programs.
		     5. UNIX distribution now builds on DECstation/ULTRIX
			and SGi/IRIX.

V2.1.5   30-Jan-92  Changed library to avoid fragmenting a single-file CDF when

                    length 512-byte records on VMS systems to allow CDFs on a
                    CD-ROM to be read.
V2.1.5b   6-Apr-92  Fixed CDFwalk for NDADS-phenomenon.  Renamed `utility.c'

                    `stdlib.h' from `cdfwalk.c'.
