+Zip 3.0
+
+We have posted Zip 3.0, July 5th 2008. This is a major upgrade
+from Zip 2.32, the current Zip 2.x release. A quick summary of
+features is below, but see the file WhatsNew for the detailed list
+of major features and upgrades as well as what's on the list for
+Zip 3.1. Send in your feature suggestions and bug reports.
+
+Quick list of major changes in Zip 3.0:
+
+- Large files. Support for files and archives greater than 2 GB using
+ large file I/O and the Zip64 extensions. Also can now have more
+ than 64K entries in an archive.
+
+- Split archives. Zip now supports split archives, zip archives
+ split into a set of files that can then be stored on removable media
+ for instance.
+
+- Unicode. If Unicode support is enabled and supported on the system
+ Zip is run on, Zip now can read paths not in the current character
+ set and store those paths in portable UTF-8 format. These Unicode
+ paths can then be used to partially or fully recreate the paths on
+ other systems depending on the character set support provided by
+ the unzip on the receiving system. In particular, this allows
+ portability of paths between Windows and Unix. Unicode comments
+ are also supported on systems where UTF-8 is the current character
+ set. Unicode comment support for other systems is expected in
+ Zip 3.1.
+
+- New command line parser. This new parser allows for command line
+ permuting, where options can appear almost anywhere on the command
+ line. This allows adding options to the end of the command line,
+ for instance. It also supports long options, allowing for
+ more readable command lines, and also allows lists for the -x
+ exclude and -i include options to appear not just at the end of
+ the command line. And some bugs in command line processing in
+ Zip 2.32 have been fixed.
+
+- Unix 32-bit UIDs/GIDs. Now UIDs/GIDs larger than 16 bits are
+ supported, but UnZip 6.0 is needed to restore these larger
+ UIDs/GIDs. If Zip detects that the current system does not use
+ 16-bit UIDs/GIDs, the old 16-bit UID/GID storage is not used
+ as putting 32-bit UIDs/GIDs into 16-bit fields can cause
+ problems.
+
+- New modes. Additional archive modes have been added, including a
+ difference mode for supporting incremental backups, a file sync
+ mode for synchronizing an existing archive with the current file
+ system (which can be much faster than creating a new archive), and
+ a copy mode that allows copying entries from one archive to another.
+
+- Compression using bzip2. Now can add bzip2 compression as a
+ compression option in Zip. bzip2 compression can result in much
+ more compact entries in some cases, but the user should verify
+ that bzip2 is supported on the target unzip before using this new
+ compression choice.
+
+- New Windows dll. The Windows dll has been updated to support the
+ new Zip64 large file and larger number of entries limits. This
+ new dll is not backward compatible with the Zip 2.32 dll, as the
+ arguments to the dll have been updated to support the added
+ capabilities, but modifying existing programs to use the new dll
+ should be simple. See the included Visual Basic example project
+ for details.
+
+- Better streaming and piping. Zip now has better support of
+ streaming and piping and handles Unix FIFOs (named pipes) better.
+
+- Gobs of new progress information. Zip can now output progress
+ information, such as how many entries processed and to go, how
+ many bytes processed and to go, and adjustable size progress
+ dots. If the initial file scan takes longer than about 5
+ seconds, Zip now outputs dots during the scan to avoid a long
+ period of quiet. Zip can also now generate log files.
+
+- Updated archive fixing. The archive fixing capability is
+ slightly improved, and now can fix split archives.
+
+- Windows Archive bit support. The Windows archive bit is now
+ supported, though the new difference mode is probably more
+ reliable than relying on the Windows archive bit for creating
+ incremental backups.
+
+- File lists. Zip can list the files that would be added to an
+ archive as well as the files in an existing archive.
+
+- Extended help. A new extended help option lists a very terse
+ summary of the major features of Zip and how to use them.
+
+- Many bug fixes.
+
+As always, see the Zip manual page for details on what Zip has and
+how to use all features.
+
+Enjoy!
