================================




Release MacZip ver1.04 beta 2
02. June 1999
--------------

1) FIX: {unzip} added one more criteria to make the recognition
         of macbinary more save.

2) FIX: {unzip} sometimes, archive entries without any extra field
         caused problems; the default setting of the extra field
         was not set back to 'unknown' properly.

3) FIX: {zip} Archive filename with invalid characters like '/' gets
         renamed. However, I do not check the complete path - needs
         some more work here.

4) FIX: {zip} Filename match was case sensitive.

6) CHG: {zip) switch to latest source level
         unzip 2.30m beta release

7) CHG: {unzip) switch to latest source level
         unzip 5.41b beta release

8) FIX: {zip/unzip 68k only) I have found a wrong compiler setting
         for the 68k version. Because of this wrong setting the 68k
         version crashed.




Release MacZip ver1.04 beta 1
30. March 1999
--------------

1) CHG: {unzip) switch to latest source level
         unzip 5.41a beta release

2) ADD: {all} Added message logging support for Syslogd
        by Brian Bergstrand. Syslogd can be found at
        http://www.classicalguitar.net/brian/apps/syslogd/
        This feature is 'under construction'.

3) FIX: {all} many small fixes and code cleanups




Release MacZip ver1.03
27. March 1999
--------------

1) CHG: {console} Like Stuffit Expander MacZip quits automatically when
         used with drag'n drop or as Helper App (Web-Browser).

2) CHG: {console} Since Macintosh users are used to be guided by their
        software in order not to do something stupid, I added a check
        to post an extra warning if the options -m and data fork only
        are both checked.
        This behavior can be disabled: See Applescript example and
        "maczip.env".

3) CHG: {zip} switch from immediate deletion to moving to the
        trash. Immediate deletion is now an option in "maczip.env".

4) CHG: {zip} enhanced progress display.

5) CHG: {zip) switch to latest source level
         zip 2.3l beta release

6) CHG: {unzip} The zip archive contains file names greater than
        31 characters. When MacZip tries to unzip the file, the
        FSpCreate command fails because the filename length is to
        long. MacZip correct this problem by trying to truncate
        the file names to the 31 character limit.

7) FIX: {zip/console} A couple of minor fixes

8) CHG: {zip} Switched file-globbing to the Info-ZIP version.




Release MacZip ver1.02
14. February 1999
-----------------

1) CHG: {zip} Changed the rule of file inclusion if switch '-X'
        is set. Following conditions are checked:
        a) if length of resource-fork is equal zero *and* the
              length of     data-fork is equal zero include the file.
        b) if length of resource-fork  greater zero *and* the
              length of     data-fork is equal zero don't include the file.
        c) if length of     data-fork  greater zero include the file.

2) CHG: {Console} Some users are very confused by the buttons "START PATH"
        and "ZIP ARCHIVE". Somehow, it wasn't clear what the intended
        meaning was. I changed the buttons to more clear labels on
        them like: "file or folder to compress" and "location of
        compressed file"

3) CHG: {Console} I changed the menu structure to be more intuitive.

4) FIX: {Console} Found a nasty bug which sometimes caused crashes
        when the Zip / Unzip Dialogbox was used.

5) CHG: {Console} Handling of file dialog is now a bit more restricted:
        e.g: it's not possible to select a file if you have to select
        a folder.




Release MacZip ver1.01
30. January 1999
----------------------

1) CHG: {console} The use of the "Current App" mechanism was clumsy
        and forces the user into the Zip or Unzip modes. This kind
        of modality is not so good for the command line. It's now
        neccessary to enter zip or unzip to choose the action.

2) FIX: {console} When Applescript sends quit to MacZip the script
        that is running shows a spinning cursor and MacZip
        does not quit.

3) FIX: {console} MacZip gots accidentally the wrong creator code
        (from BBedit)




Final Release MacZip ver1.0
---------------------------

Released 21. January 1999




9. Beta release 06.December.1998
---------------------------------

1) CHG: {console} The checkbox of Filedialog (for extract path and file path)
        "Show all files" is now selected by default.

2) CHG: {unzip/standalone} changed prototypes of mac[f]printf() to return
        an int number (better ANSI conformance);

3) FIX: {unzip} repaired "stdout/stderr" mode of macwrite(). So func
        MacMessagePrnt() is now obsolete and removed.

4) ADD: {zip/unzip} Compressed Mac3 extra-fields are now supported
        (Thanks to Christian Spieler)

5) ADD: {unzip} Extraction of ZipIt archive are now supported. This support
        is not complete: Filenames are correct but folder names are only
        restored with the public directory names.

6) ADD: {zip/unzip} Improved documentation.

7) FIX: {unzip} Function isZipfile() is completely rewritten.

8) CHG: {zip/unzip) switch to latest source level
        zip 2.3i beta and unzip 5.4 final release

9) ADD: Applescript event "do_cmd".

Unless there are big bugs found, this release will be the last
beta release. The final release will come out in January 1999.




8. Beta release 20.November.1998
---------------------------------

1) CHG: {zip/unzip) switch to latest source level
        zip 2.3h beta and unzip 5.4 final release

2) ADD: {zip} Zip finds "namelocked" files also, if switch "-S"
        is set.

3) FIX: {unzip} Function isZipfile() fails if the zip archive
        has a comment.

4) CHG: {zip} added some small speed improvements to pattern matching and
        isZipFile() function.

5) FIX: {unzip} Display of comments is fixed.
        UzpMessagePrnt() is replaced by MacMessagePrnt(). I do not care
        about ansi-bombs. I'm not sure, so this fix may be changed later.

6) RMV: {unzip} Buildin More capability is removed since it's already built
        into the GUI-App.



7. Beta release 09.November.1998
---------------------------------

1) CHG: {all} switched to Metrowerks Codewarrior Pro 4

2) FIX: {unzip} Display of comments stored in the zip-file is
        now fixed

3) FIX: {zip} Fixed display of the zip help-screen.

4) CHG: {zip/unzip} Changed special dir 'Re$0urce.Fk' to 'XtraStuf.mac'
        (see entry at 13.June.1998 item 3). I found it more descriptive for
        users outside the mac-community.

5) CHG: {all} switched to MoreFiles 1.4.9.

6) CHG: {console} changed behaivor of the file open dialog: The select
        button is now always enabled.

7) ADD: {all} Environment variables are now supported.
         Basically, it is possible to add timezone (= TZ environment variable)
         support here, but it's not yet implemented.
         See "MacZip.Env" for further info.

8) RMV: {console} Targets "zip only" and "unzip only" are removed.



6. Beta release 09.September.1998
---------------------------------


1) CHG: {Zip/Unzip} Metrowerks Standardlibrary time funktions are
        rather broken and incomplete so I was forced to rewrite the
        funktions: mktime(), localtime(), gmtime() and time().

2) ADD: {Console} Added Pause Funktion for screen output.
        The Pause-Function is selfadjusting: Count of lines is depending
