What’s New  in This Release:

- Big amount of code was changed in this beta version.

So don’t use it for important data compressing.

And test archive after compressing.

- Unified command line interface to GUI and console versions

- 7-Zip now can extract or test several archives in one command

- 7-Zip now doesn’t interrupt the compressing when file is locked by

other application. 7-zip just skips that file and show warning.

Note: previous versions of 7-Zip had bug, so they can not unpack

non-solid and some solid 7z archives with such skipped files.

- Command line interface was changed:

- now it’s possible to use absolute pathnames

- syntax simplification:

was: 7z a a Folder1* Folder2* -r

now: 7z a a Folder1 Folder2

- now it’s possible to use complex wildcard commands, like **111**

- More smart detection of archive type for files with unusual

file name extensions

- Supporting for RAR archives with encrypted headers

- CPIO format supporting was improved

- For GZip and BZip2 formats you can:

- Compress from stdin (-si switch)

- Compress to stdout (-so switch)

- Extract to stdout (-so switch)

- 7-Zip File Manager:

- Split and Combine commands

- new list view options: Full row select, Show grid lines

- Internal reconstruction

- Some bugs were fixed
