- 7-Zip now can update solid .7z archives.

- 7-Zip now supports XZ archives.
- 7-Zip now can unpack NTFS, FAT, VHD and MBR archives.
- 7-Zip now can unpack GZip, BZip2, LZMA, XZ and TAR archives from stdin.
- 7-Zip now can open/copy/compress disk images (like \\.\c:) from \\.\ folder.
- 7-Zip File Manager now doesn't use temp files to open nested archives
stored without compression.
- New -scrc switch to calculate total CRC-32 during extracting / testing.
- New -scc{WIN|DOS|UTF-8} switch to specify charset for input/output (default = DOS).
- Some bugs were fixed.

Don't use this beta version for important data. Call "Test" command after each compressing operation.
