See the announcement file zip30.ann for a quick summary +of all features and changes in Zip 3.0. Also see the file README for +release information, INSTALL for installation procedures, and the manual +pages zip.txt, zipsplit.txt, zipcloak.txt, and zipnote.txt for how to use +the new features. The file CHANGES has all the day-to-day changes made +during development. + + +Below are some of the more significant items on the list for Zip 3.1 +(see ToDo for a more complete list): + +- AES encryption. +- Extended attributes for Windows, Linux, and Mac OS X. +- Support -d@ for deleting list of files. +- Decide if -R, -i and -x should use external rather than internal patterns. +- Though Unicode paths have been implemented and tested, Unicode comments + are not yet supported (except for comments on UTF-8 native systems which + are supported). +- Verbose mode -v may still need work. +- When pattern is directory add end / automatically. +- Add C# example for Zip 3.0 (need to be converted to new DLLs) - original + C# example added with note. +- Path Prefix maybe, so entries added to an archive can have a directory + path string prepended to each path. +- UNC path support maybe. +- Support for other languages maybe. +- Send in your suggestions. +- ... + + +MAJOR CHANGES BY BETA VERSION +----------------------------- + +New things in Zip 3.0 since Zip 3.0h: + +- Unicode fixes. +- Test and fix various ports as needed. +- Update Win32 resource to support more Windows ports. +- Add djgpp 2.x makefile that includes bzip2. +- Add Win32 version resource to Win32 executable. +- Bug fixes. +- Documentation updates. +- Package for release. + + +New things in Zip 3.0h + +- Allow -@ and -x to work together. +- Unicode code cleanup. +- Allow forcing use of UTF-8 storage in standard path and comment. +- Update symbolic link checks. +- Add support for storing 32-bit UIDs/GIDs using new extra field. + Backward compatible support for the old 16-bit UID/GID extra field + remains if Zip is compiled on an OS that has 16-bit UID/GID + storage. +- Update VMS notes. +- Directory scan using -AS (include only files with Windows archive + bit set) now ignores archive bit on directories to include all files + with archive bit set in all directories. Also, to avoid empty + directories being created, -AS now does not store directory + entries. +- Add Unix IBM support. +- Change -W to -ws to free -W for later use. +- Fix large file support for MinGW. +- Fix large file support for bzip2. +- Fix compile error in ZipCloak when UNICODE_SUPPORT is not enabled. +- Fix Unicode bug in ZipCloak involving Unicode paths. +- Long Unicode escapes changed from #Lxxxxxxxx to #Lxxxxxx to shorten + paths with escaped Unicode. +- Bug fixes. + + +New things in Zip 3.0g + +- Add split support to VB project for Zip64. +- Disable reading of Unix FIFOs unless new -FI option used to avoid an + archiving operation stopping when it hits an active unfed FIFO. +- The "[list]" wildcard expression (regular expression matching of any + character or range of characters in list) is now disabled on DOS and + Windows as it has caused confusion when filenames have [ and ] in + them. The new -RE option reenables it. +- Add negation to many display options such as -dc and -db. +- Allow -FF to read and fix archives having local entries that appear + after central directory entries. +- Bug fixes. + + +New things in Zip 3.0f + +- bzip2 - The bzip2 compression method looks supported for at least + Windows, Unix, and VMS using the bzip2 library. A new option, -Z cm, + selects the compression method. + +- Split archives - Can now use -s to create a split archive. The + default is to update split files as the archive is being written, + which requires all splits to remain open until the archive is done. + This should be no problem when writing the archive to a hard drive, + for example, and this approach creates archives that should be + supported by all unzips that support splits. Adding the -sp option + enables split pause mode that instead writes splits that do not + need updating and pauses Zip after each split. This allows splits + to be written directly to removable media, however -sp archives + may not be as universally compatible. + +- Unicode support - Zip now stores Unicode paths that should be more + portable across character sets and languages. The unzip must have + Unicode support enabled or the Unicode paths are ignored. If + reading an archive with Unicode paths, unsupported characters are + replaced by #Uxxxx and #Lxxxxxxxx escapes in the file name. Option + -UN controls how Unicode is handled. Also, on systems where the + current character set is UTF-8, preliminary support for the new + General Purpose Bit Flag, bit 11, UTF-8 flag, that indicates UTF-8 + is stored in the path and comment fields is implemented for paths. +- Unicode on Win32 - On WIN32 systems that support the wide character + calls (mainly NT and later systems using NTFS), when UNICODE SUPPORT + is enabled Zip will now do directory scans using Unicode and convert + the Unicode paths to the local character set for storage in the standard + path field and store UTF-8 in the Unicode extra field. This allows + directory scans to complete successfully regardless of the character + set the path is in. On Win9x systems wide character scans are not + generally supported and Zip automatically uses a local character scan + instead. + +- Keep extra fields option - The default operation has been, and continues + to be, to read then strip old extra fields when reading entries from an + existing archive and then recreate the extra fields that Zip knows about. + Extra fields specific to each operating system get added by default also. + The new option -X- (negated -X) keeps any old extra fields, copying + them to the updated archive unchanged (unless Zip has updated them). + The unnegated -X still strips most all extra fields except Zip64, + Unicode, and UT time. + +- License - minor updates to the license. + +- Windows OEM - When compiled with WIN32_OEM (the default for WIN32), + Zip on WIN32 now stores OEM paths, which should be more compatible + with other zips and should fix some character set problems. +- Windows Archive Bit support - On Windows can now use new -AS + (include if archive bit set) option to select files with the DOS + archive bit set and use new -AC (clear archive bits) option to clear + the archive bits on files after the archive has been created. + But -DF is probably better. + +- Difference mode - A new option -DF (--dif) creates an output archive + that includes only files changed or new since the input archive was + created. Can use to create incremental backups. +- File Sync - The new option -FS enables File Sync, a new mode that + synchronizes the entries in an archive with the files on the file + system, adding updating, and deleting entries as needed. This + should create the same results as creating a new archive, but + since existing entries are copied, may be much faster. + +- Copy Mode - A new --out option allows creating a new archive with a + different name than the input archive, leaving the input archive + unchanged. This allows updating split archives. It also allows + for a new copy mode to select entries in one archive and copy them + directly to a new archive. +- Empty archives - Now an empty archive is created when -i or -i@ is used + and the file patterns given do not match anything. This has been + requested to support scripts. + +- Global dots - A new -dg option now displays progress dots as -dd does, + but instead of displaying them for each file, the dots track the total + bytes read for the archive. The -dg option also works when -q is used + to disable most output, which allows for something like zip -qdgds 100m + to be used to not display specific files but display a dot every 100 MB + as a global status. +- Date range - Can now use -t and -tt to set a date range +- Fix options - Option -F redone and can recover files from an archive + with a mostly complete central directory more reliably, but no longer + can handle truncated archives. Option -FF redone and now can salvage + files from slightly more damaged archives, including truncated archives. + In some ways -F is less powerful but more stable than it was and -FF will + be needed where -F in Zip 2.32 was enough. One big change is -F and -FF + both now support split archives. +- Console writing - Updates to how messages are written to the console have + been made including more consistent handling of line breaks. +- Show Files options - Option -sf lists the files that would be operated + on. This option can be used alone to list the files in an archive. + Also see options -su and -sU for showing Unicode paths. +- UnZip Check - Now check that UnZip 6.00 or later is being used for + unzip if testing a Zip64 archive. A new option -TT can be used to set + the unzip to use with the -T check. Currently UnZip does not support + split archives so split archives can't be tested by UnZip. +- Streaming - Directories are now handled better when streaming. +- Case matching - Normally all matching against archive entries is case + sensitive, so *.BAR will not match or find foo.bar in an archive + when deleting, copying, or freshening entries (deleting and copying + only on VMS). New option -ic (--ignore-case) enables case insensitive + matching. Currently -ic is only implemented on WIN32 and VMS. + +- Delete date bug fixed - Bug when using -d to delete files while + using -t or -tt to select the files based on date is fixed +- Large file encryption bug fixed - Fix for bug that very rarely + results in bad data being stored when deflating and encrypting + uncompressable data and resulting in CRC errors when extracting, + but the chance of error increases with file size (thanks to + WinZip for finding this bug). See CHANGES for details. + + +New things in Zip 3.0e + +- Bugs described in Debian patches 004 (unix configure script update) and + 005 (large path bug) fixed +- Various fixes +- Add optional running stats and also end stats if not all files could + be read +- Options -l and -ll now do quick binary check on first buffer and skip + formatting if first buffer has binary - still check at end to note + if formatting was done on file that was later determined to be binary, + but now potential file corruption is generally avoided +- Main binary check now uses new algorithm that should also treat UTF-8 and + other similar encodings as text, allowing proper line end translation + for UTF-8 files +- When output is not updatable by seeking back and Zip64 is enabled, output + is forced to Zip64 to avoid possible later need for Zip64 when not enabled +- More work on splits, but still not usable +- Fixes for djgpp +- Add log file capability to save all errors and optionally messages +- Add code to test for a Zip64 archive when compiled without Zip64 support +- New VC6 projects for Win32 and WinDLL +- Updates to extended help +- Changes to force-zip64 option +- ZE_BIG error now given also for files too big to read or write +- Fix file delete bug +- Update license +- Update export documentation +- Add VMS extended filename support +- Add directory traversal improvements, some for Win32 ports and some for + all ports, that can result in a 10 times increase in speed in some cases + + +New things in Zip 3.0d + +- Some large file crypt fixes +- Some updates to support WiZ +- On VMS, changed -V (/VMS) processing to truncate file at EOF, allowing + greater compatability with non-VMS systems. New -VV (/VMS=ALL) option + saves all allocated blocks in a file. (Previously, -V did neither.) +- On VMS, pushed 2GB file size limit with -V out to 4GB +- On VMS (recent, non-VAX), with SET PROCESS /PARSE = EXTEND, + command-line case is preserved. This obviates quoting upper-case + options, like -V, when enabled +- On VMS, fixed problems with mixed-case directory names. Also changed + to keep ODS5 extended file name escape characters ("^") out of the + archived names in simple cases +- Changes to the display dots +- Option -W should now force wildcard matching to not cross directory + separators. For example, a/b*r/d will match a/bar/d but not a/ba/r/d +- Option -nw should turn off all wildcard matching so foo[bar] is matched + literally and [bar] is not considered a regular expression +- Atheos port +- Debugging of Unix and VMS large file ports. Most features may work now + on these ports for large files. Still need to fix 2 GB to 4 GB when not + compiled with large file support +- On VMS, added an open callback function which (where supported) senses + the process RMS_DEFAULT values for file extend quantity (deq) + multi-block count (mbc), and multi-buffer count (mbf), and sets the + FAB/RAB parameters accordingly. The default deq is now much larger + than before (16384 blocks, was none), and the default mbc is now 127 + (up from 64), speeding creation of a large archive file. The "-v" + option shows some of the activity. On old VMS versions, RMS_DEFAULT + sensing (GETJPI) fails (silently, without "-v"), and no changes will + be made. Even there, (DCL) SET RMS /EXTEND = <big> can help + performance. RMS_DEFAULT values override built-in default values. + + +New things in Zip 3.0c + +- Converted to using 64-bit file environment instead of transitional functions + like fseeko64 for ports that support it +- Added "--" argument to read all following arguments as paths +- Second help page added +- Binary detection adjusted from 20% binary is binary to 2% +- When -R and -i used together now -i has precedence over -R +- Archive names with spaces can now be tested on MSDOS and Win32 + + +New things in Zip 3.0b + +- Fixed ifdefs so can test base code by compiling with NO_LARGE_FILE_SUPPORT, then + compiling with NO_ZIP64_SUPPORT to test 64-bit file calls (if port enables) but + otherwise use base code, and compiling normally to enable Zip64 code +- Unix Zip64 fixes - should now be able to create and read large files +- WinDLL changes to support Zip64. Zip 3.0 dll named Zip32z64.dll +- New VB example to show use of Zip32z64.dll +- New options -sc (show final command line and exit) and -sd (show each + step zip is doing, a little different than verbose which is still there) added + to help debug but both or at least -sd might go away in the release +- Some minor posted bugs fixed (see Changes) + + +New things in Zip 3.0a + +- Initial Zip64 support allowing large files and large numbers of files +- New command line processor +- Other changes, see file Changes + + +Note: Zip 2.4 was never released. That code was the start of the Zip 3.0 +effort above. + + +New things in Zip 2.3 + +- IBM OS/390 port (Unix like, but EBCDIC) by Paul von Behren +- Apple Macintosh (MACOS) port by Dirk Haase +- Theos port by Jean-Michel Dubois +- Multibyte characterset support by Yoshioka Tsuneo +- Support for ISO 8601 date format with -t and -tt options +- Info-ZIP license + + +New things in Zip 2.2 + +- BEOS port by Chris Herborth +- QDOS port by Jonathan Hudson +- TANDEM port by Dave Smith +- WINDLL port (16-bit Win 3.x and 32-bit WinNT/Win95) by Mike White +- SYSV packages support by John Bush +- zip -P SeCrEt encrypts entries in the zip file with password SeCrEt + (WARNING: THIS IS INSECURE, use at your own risk) +- zip -R recurses into subdirectories of current dir like "PKZIP -rP" +- zip -x@exclude.lst excludes files specified in the file exclude.lst +- zip -i@include.lst includes files specified in the file include.lst +- zip -@ only handles one filename per line, but supports whitespace in names +- zip -t mmddyyyy, 4 digit year number for uniqueness of years beyond 2000 +- zip -tt mmddyyyy only includes files before a specified date |
