09.November.1998
================================



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 
        on the window size. 
        
3) CHG: Extra-Field layout is changed: All datas are now in little-endian 
        format (see appnote)
        
4) ADD: {Console} Added an option to test the archive automatically 
        after zipping. This option is only via Zip-Dialogbox available 
        because it needs the unzip-module also.

5) CHG: {Zip} code is now up to date with the latest beta 2.3f.

6) ADD: {Console} Added (drag'n) drop support. Drop on the MacZip icon. 
        The following situations are supported: 
                    1. drop of one or more zipfiles (action = unzip)
                       each archive will be extracted in a separate folder
                    2. drop of a folder (action = zip -r )
                       The complete folder (inclusive sub-folders) 
                       will be zipped
        Not (yet) supported is currently: dropping more than one file 
        to compress. Workaround: Put all your files in one folder and 
        drop that folder on MacZip.
        MacZip recognize zip-archives automatically.


5. Beta release 21.Aug.1998
----------------------------


1) ADD: {Console} Userinterface has now a Statusbar to show the 
        Progress.
        
2) ADD: {Console} It's now possible to stop the run of Zip/Unzip
        with the well known shortcut [Command] + [.]
        
3) CHG: {Console} Improved user-entry routine.

4) ADD: {Zip/Unzip} Crypt-code added. It's now possible to 
        encrypt/decrypt archives. 
        
5) RMV: {Unzip} Removed the warning of PKZip/Mac archive. 
        Unzip gets confused with the extra field of PKZip/Mac. So I assume 
        the extra field isn't compatible with Info-Zip's definition.

6) CHG: switched to Metrowerks Codewarrior Pro 3
        this includes:
        - new Universal Interfaces 3.1 Headers
        - improved codegeneration

7) CHG: {Zip} code is now up to date with the latest beta 2.3e.
        
8) CHG: {Unzip} changed function names wprintf, wgets .. to macprintf, macgets ..
        to avoid naming conflict standart library.

9) ADD: {Zip/Unzip} FXinfo, Mac-Pathname, file-dates and Finder-Comments 
        are now stored in the extra-field. Extra-field layout is 
        changed accordingly. Unzip uses now the filename stored in the 
        extra-field when unzipping.

10) CHG: {Unzip} code is now up to date with the latest beta 5.33g.
 
11) CHG: {Unzip} code is (again) up to date with the latest beta 5.33h.

12) ADD: {Unzip} following switches were added:       
       -J     [MacOS  only] ignore mac extra info. All macintosh
              info are not restored. Datafork and resource-fork
              are restored separatly.
              
       -i     [MacOS  only] ignore filenames stored in mac extra
              field. Use the most compatible filename stored in
              the public field. 
              
       -E     [MacOS  only] show mac extra field during restoring

13) ADD: {Zip/Unzip} Charset MacRoman to ISO8859 Latin and vice versa

14) RMV: {Zip} -N option removed. This MacZip crashes using this option.
         I will fix it later.


I think I'm very close for a final release of "MacZip 1.0" :-)
        
        
        
4. Beta release 27.June.1998
----------------------------

26.June.1998
------------

1) FIX: {Zip} extra field size value was wrong.



25.June.1998
------------

1) CHG: {Zip} code is now up to date with the latest beta 2.3d.
        So both modules, zip & unzip, uses now latest beta.

2) ADD: {Zip} added a UT extra-field for better compatibility.

3) CHG: {Unzip} changed the code to find the mac extra-field. 
        Unzip has to look for a mac extra-field because 
        mac-archives has now two extra-fields (UT + M3). 

4) CHG: {Unzip} changed the method to move extra-field data to 
        the internal extra-structure. 
        Old method was just BlockMove of the ef_structptr to ef_memptr.
        This method was dangerous because not all members of the
        structure seamless aligned. There are may be some fill 
        bytes in the structure depending on the compiler setting. 

5) ADD: {Unzip} added a warning if unzipping a ZipIt/PKZip archive.
        ZipIt/PKZip archives are usually additionally coded somehow.
        InfoZip's Unzip will *not* decode the files. So extracted
        files are may be not decoded. (see also 6. and 7.)
        
6) ADD: ZipIt (the Shareware Tool) has now a new extra-field signature: 
        0x2705. Found in "ZipIt 1.3.8". I added a new macro: EF_ZIPIT2
        
7) ADD: Added PKWare's extra-field signature: 0xCF77.
        Found in "PKZIP v2.03". I added a new macro: EF_PKMAC

8) ADD: {console} It's now possible to save all screen outputs
        to the disk.

9) RMV: {console} this is the first beta without expire-date.
        

16.June.1998
------------

1) FIX: {Unzip/console} Extract path now defaults to current-dir if
        no path is given.

2> CHG: {Unzip} creates now a extract-folder by default. This behavior 
        differs to the commandline tool of Unzip on other platforms. 
        However, for a mac-user is this behavior more convenient.


3. Beta release 15.June.1998
----------------------------

15.June.1998
------------

1) CHG: {unzip/zip} I changed the layout of the extra field 
        to support more data. 
  

14.June.1998
------------

1) FIX: {Unzip} adjusted time_t value with an correct offset value.

2) FIX: {Unzip} removed all unused code based on unfinished ideas by 
        former porter(s).

3) CHG: use of shared code izshr 032.

13.June.1998
------------

1) FIX: {Unzip} Filenames are only converted when needed. When zipping 
        with the switch 'datafork only' the filenames are shorted which 
        was wrong.

2) CHG: {Unzip} code is now up to date with the latest beta 5.33f.

3) CHG: {Zip} Changed the naming rule of filenames from old Johnny Lee's 
        to my implementation. Johnny Lee's idea is based on change of the 
        filenames which cases several problems when unziping on a non mac 
        plattform. My idea is to add a special directory: 'Re$0urce.Fk'. 
        For the future: Zip will create archives according the new nameing 
        rule. However unzip will be compatible with old nameing rule. 
        See also 4.

4} ADD: {Unzip} Added a new nameing rule for resource forks filename. 
        Resource forks are now stored in a special directory: 'Re$0urce.Fk'. 
        This naming rule make it easier to for other platforms to use
        mac zip-files.
        
        

11.June.1998
------------
1) FIX: {Zip} Internal file attribute is set to BINARY by default 
        when zipping resource forks otherwise Unzip will create 
        sometimes wrong resource-forks.
        
2) CHG: {Unzip} code is now up to date with the latest beta 5.33e.




2. Beta release 10.June.1998
--------------------------

1) FIX: {Unzip} Long pathname fix solved. Unzip is now able to extract 
        archives with path longer than 256 chars. 
       
2) CHG: {Unzip} removed all conversion from c-style string to 
        pascal-string (see fix 1)
     
3) ADD: {Unzip} Finderinfo of folders are also restored.

4) ADD: {Console} Added info about current path in the command-line box.

5) FIX: {Console} Construction of the command-line of the unzip-dialog 
        box fixed.



First beta release 06.June.1998
-----------------------------

no history.
Just to many code was neccessary to build the first mac-port.


Start of the port MacZip
February 1998


--------------------------------------------------------------------------------
Legende:

FIX: fixes a bug
CHG: inform about changed items.
ADD: added feature
RMV: removed Item

{Unzip}   -> only related to the Unzip-module
{Zip}     -> only related to the Zip-module
             These are just libraries and are linked into the console-app.

{Console} -> only related to the Userinterface (not SIOUX)
             MacOS has no tool like a command-line. So it's neccessary 
             to write wrapper around the command-line tools.
