- Version 2.0 15 Aug 92
- ------------------------------
-
- Summary of changes, from most important to small bug fix, since version 1.1 :
-
-
- - New compression algorithm
- -------------------------
-
- Named 'Deflating', it compress better than imploding and is
- compatible with the upcomming PKZIP 2.0. At this time, PKZIP 2.0 is not
- released, but an alpha version with deflating, v1.93, is available.
-
- Using a command line, you may select this algorithm with the -ed option.
- The default algorithm, for this version, is still Imploding.
- Using the Gem interface, you may select this algorithm in the Config
- dialog box.
-
- This algorithm has three variants : one that compress faster but not so good,
- one medium, and one which compress best but slowly. There are buttons to
- select the one you want in Gem. Using a command line, -edf gives you the
- fast one, -edb the best one, and -ed the medium.
-
- Note that at the time of the release, not all versions of ZIP on all
- computers are able to extract deflated files.
-
-
- - Self extracting file support
- ----------------------------
-
- You may use ZIP2TOS.PRG to convert a zip file to a .TOS program which
- will contains the compressed files and will extract them when launched.
-
- Without parameters, you will be prompted for the file to convert. You may
- also calls it with the zipfile names in parameters, from the desktop (drag
- a file) or a shell (zip2tos *.zip)
-
- A self extracting file should contains _only_ deflating or stored files. It
- will be unable to explode or unshrink files. This is _not_ checked when
- doing the conversion.
-
- A self extracting file may be used as a normal zip file. Using STZip >1.3,
- you will be able to change the comments, list, extract, add or delete
- compressed files in the self extracting file.
-
-
- - Crypting and uncrypting files
- -----------------------------
-
- A compressed file inside a zip may be crypted. STZip use the same
- algorithm as PKZIP,
-
- You may specify a password using the -w switch when using the command
- line interface, or by clicking in the "Crypt box" in the Gem interface.
- The files to be compressed will be encrypted using that password.
-
- That password will be also used when extracting files. If you forgot
- to specify it and STZip encounter a crypted file, it will prompt you.
-
- (i.e. : if you compress files using password BURP and extract them
- without leaving STZip, STZip won't prompt you for the password since it
- still has BURP in mind).
-
- STZip is also able to tell you if the password supplied for extracting a
- file is wrong. Note that the password is not stored in the file (would be
- stupid!).
-
-
- - Updating and freshening a zipfile
- ---------------------------------
-
- 'Adding' would compress all the selected files, wether they are already
- in the zip or not.
-
- Three new modes are available :
-
- -Freshening : only specified files that are already in the zip and are
- newer than those in the zip will be added.
- -Updating : only specified files that are already in the zip and are
- newer than those in the zip, _AND_ the specified files that are
- not in the zipfile will be added.
- -Using a date line : only the files changed after the specified date will
- be added.
-
- To use that in Gem, click on the 'Add Mode' box, and select what you want.
- To use that in a command line,
- freshening is -f : stzip -f backup *.c
- updating is -u : stzip -u galery *.gif
- date line is -t : stzip -a -t011692 fip *.prg
- Will add all *.prg files created or changed after Janury 16th 1992.
- Note the US date format !
-
- - Minor changes
- -------------
-
- - Added 'Delete original files' in the Config box in the Gem interface. If
- selected, the original files on disk will be deleted after compression.
-
- - In Gem, new window for displaying information, so that it should be
- possible to compress in background using MultiTOS.
-
- - STZip checks for its configuration file in its home directory
- using shell_find. I think that doesn't work on TOS < 1.4.
-
- - STZip detects files packed with Ice and Atom and does not try to compress
- them (infos supplied by David Ducassou). Also checks files packed with
- compress, freeze and PfxPack as does older versions.
-
- - Added 'Check Zipfile' in the Gem interface. That checks if the zip
- file extracts correctly.
-
- - If you're in the zip directory DIR while in Gem, the files you may compress
- will be put in that directory. That's not new, the news is that you may do
- the same using the command line interface, by using the -i option :
- stzip -a burp -i dir *.*
- will add all files in the directory dir OF the zip file.
-
- - File attributes are handled : stzip will also adds hidden and system files,
- and will extract those files with their original file attributes.
-
- - Added an option to force the free disk space display on Tos < 1.4
- (this is generally slow).
-
- - More drive letters in Gem.
-
- - Redirection >AUX: is now possible using the command line interface
-
- - Bug fixes
- ---------
-
- - Fixed bug when extracting 0 length files on TOS 2.x and 3.x, reported
- by Gianfranco Marino and willy.
- - Fixed bug when displaying files with lines separated by CR, reported
- by Robert Eckardt.
- - STZip wasn't adding the default .ZIP extension when the file name typed
- in the file selector was just 8 characters long (Robert Eckardt).
- - Fixed bug with vro_cpyfm, reported by Wilfried Behne
- - In Gem, the zip size is now updated after a delete, reported by willy
- - It is now possible to display a Stored file in the display window

-
- Version 1.1 14 Jan 92
- ------------------------------
- Well... Some bugs in 1.0 needed to be unimplemented ! :-(
- - Fixed incompatibility bug with PKUNZIP happening sometimes
- - Corrected bug when changing the zipfile after having edited the
- comments of the old one (was overwriting the new one)
- - You may now add a file in a subdir of a zipfile, it will be compressed
- with the correct path (it was added in the root of the zip file before).
- - Corrected bug when compressing many files in .TTP
- - The path stored in the config file wasn't used in some functions (resulting
- in disk selector containing directories of a path and files of another one !)
- fixed (reported by willy)
- - Fixed bugs with MultiGEM reported by Peter Kocourek
- - Fixed bug when displaying files with lines ending with LF only (not CR LF)
- - Improved file display (horizontal slide etc)
- - Faster compression on highly redondant file (was very slow)
- - Only ESC stops compression or decompression (before any key was stopping)
- . Added confirmation when deleting a file on disk.
- . Fixed bug when PATH was empty
- . Fixed bug when zip file name was >45 chars

-
- Version 1.0 28 Dec 91
- -------------------------------
- - New implementation of the Imploding algorithm. It is now faster
- (especially for text files) and uses less memory.
- - You may display files in a window, compressed or uncompressed !
- Press HELP for help (search string, save file, clipboard, change fonts)
- - Added edition of comments in GEM.
- - Delete files in zip and overwrite file in zip is supported both in GEM
- and TTP.
- - Included resource in the program and added color support.
- - Fixed problem with zipfile being sometimes corrupted when adding a file
- - Added handling of a config file. It is loaded automatically if found and
- may be saved in the dialog box 'configuration'. It contains also the
- directory where to find zipfiles (used in the file selector) and the 'DISK'
- path.
- - Included english and german translations of the documentation made by
- Peter Kocourek and Juergen Kiesheyer. Thanks to both !
- - With new features and inclusion of the resource in the program, stzip.prg
- has largely grown in size. People not using GEM might be low in memory or
- might want to reduce loading time, so I included ZIPJR.TTP, which is a
- command line only version of STZIP, without GEM handling. Features are
- exactly the same.
- - Added check archive (-c) and extract files to screen (-s) in command line.
- - Faster scroll in the window when compressing/extracting in GEM
- - On TOS < 1.4, doesn't display free disk space because it's slow
- - You may stop compression/decompression in GEM by pressing a key
- (it will only take effect when displaying something)
- - Delete original files after compression (ie : -am) works as expected in TTP.
- - Disable FormDoIt on some buttons (file names etc) so that there's no
- alt-key bindings on these buttons.
- - Fixed problem with files packed with PKZIP and authenticity verification
- - Fixed compatibility problem with some versions of UNZIP (<3.0)
- Bugs :
- - When LTMF 1.14 is active, pressing a key to stop compression in Gem
- doesn't work.
- - Selection on multiple file (by keeping mouse button pressed) doesn't
- work as expected when FormDoIt is active.
- - Display a file in GEM which was Stored is not yet possible.

-
- Version 0.9 19 Jun 91
- --------------------------
- This is a bug fix version.
- -Fixed problem (was terribly slow and bad ratio) with imploding highly
- compressible files (such as data base etc).
- -Fixed problem computing CRC when imploding small files.
- -Fixed problem with AMCGDOS ('invalid handle').
- -Fixed problem with zip file of length 0.
- -Can select multiple files in one clic in Gem.
- -'@list' option in command line and redirection without shell are working now.
- -Handles errors in GEM and in Implode correctly.
- -Added ARGV support in command line.
- -Can set a zip file comment from a file using '<' redirection
- (e.g. stzip -az file.zip dummyfile <bbs.txt)
-
- The following 'bugs' are known and will be corrected as soon as possible :
- - support of all screen resolutions
- - delete/update files in a zip
- - changing comments in gem
- - store file when the compressed data is larger than the original
- - the -m option should be considered as unimplemented. it only does a
- Fdelete on the parameter, without handling directory change, wildcards,
- ~ and @
-

-
- Version 0.8 9 May 91
- --------------------------
- Fixed compatibility problem with PKUNZip/Implode, doesn't compress better
- than PKZip anymore :-(
- You can use the old incompatible compression algorithm with the -ej
- switch. It is strongly suggested not to use it unless you are sure
- nobody will extract the file on a PC.
- Hope to increase compression ratio in next release.
-
- Version 0.7 21 Apr 91
- --------------------------
- Big text files couldn't implode without bombing, fixed.
-
- Version 0.6 4 Apr 91
- --------------------------
- Imploding is now the default algorithm, and detects text files to use
- better parameters. Added drive buttons.
-
- Version 0.5 3 Apr 91
- --------------------------
- Added imploding, use the -ei switch to select it in command line, or go in
- the configuration box in gem.
-
- Version 0.4 29 Dec 90
- --------------------------
- Compiler change, stzip.prg is 22k smaller. Added disk format.
-
- [sleeping]
-
- Version 0.3 1 Jun 90
- -------------------------
- Bugs changed, Comments. -z (set zipcomment) and -t (set zipfile date)
- switchs added.
-
- Version 0.2 30 April 90
- -------------------------
- Shrinking is nearly 65% faster.
- Many bugs removed. No more limitation in the number of files added.

- (store only) is useful), and a -p switch to store paths when not
- recursing into subdirs.
-
- Version 0.1 5 April 90
- -------------------------
- First beta release.
