- Summary of Changes from Zoo version 1.51 to version 2.0.
-
- - New modifiers to the list commands permit several new output
- formats.
-
- - Timezones are handled.
-
- - A bug was fixed that had made it impossible to individually update
- comments for a file whose name did not correspond to MS-DOS format.
-
- - The shared library on the **IX PC can be used.
-
- - VAX/VMS is now supported reasonably well.
-
- - A comment may now be attached to the archive itself.
-
- - Extracted files can optionally be forced to overwrite existing
- read-only files.
-
- - Extracted files will not overwrite newer existing files unless
- specifically requested.
-
- - File attributes (lowest nine mode bits) are preserved for **IX
- systems.
-
- - Multiple generations of the same file are supported.
-
- - Zoo will now act as a pure compression or uncompression filter on a
- single input data stream.
-
- - A bug was fixed that could cause removal of a directory link by the
- superuser.
-
- - The ability of Zoo to recover data from damaged archives is greatly
- improved.
-
-
- Summary of Changes from Zoo version 2.00 to version 2.01.
-
- - A bug was fixed that had caused the first generation of a file to
- sometimes unexpectedly show up in archive listings.
-
- - A bug was fixed that had caused the MS-DOS version to silently skip
- extracting files for which there was not sufficient disk space; an
- error message will now be given.
-
- - A bug was fixed that had sometimes made it impossible to
- selectively extract a file by specifying its name, even though all
- files could be extracted from the archive by not specifying any
- filenames. This occurred when a file had been archived on a
- longer-filename system (e.g. AmigaDOS) and extraction was attempted
- on a shorter-filename system (e.g. MS-DOS).
-
- - A change was made that will make zoo preserve the mode (file
- protection) of a zoo archive when it is packed. This is effective
- only if zoo is compiled to preserve and restore file attributes.
- Currently this is so only for **IX systems.
-
- - A bug was fixed that had caused an update of an archive to not
- always add all newer files.
-
- - Blanks around equal signs in commands given to "make" were removed
- from the mk* scripts for better compatiblity with more **IX
- implementations including Sun's.
