What"s new after 7-Zip 9.38 Beta::

7-Zip File Manager now can operate with alternate file streams at NTFS
volumes via "File / Alternate Streams" menu command.
7-Zip now can extract .zipx (WinZip) archives that use xz compression.
new optional "section size" parameter for BCJ2 filter for compression ratio improving.
Example: -mf=BCJ2:d9M, if largest executable section in files is smaller than 9 MB.
Speed optimizations for BCJ2 filter and SHA-1 and SHA-256 calculation.
Console version now uses stderr stream for error messages.
Console version now shows names of processed files only in progress line by default.
new -bb[0-3] switch to set output log level. -bb1 shows names of processed files in log.
new -bs[o|e|p][0|1|2] switch to set stream for output messages;
o: output, e: error, p: progress line; 0: disable, 1: stdout, 2: stderr.
new -bt switch to show execution time statistics.
new -myx[0-9] switch to set level of file analysis.
new -mmtf- switch to set single thread mode for filters.
The BUG was fixed:
7-Zip didn"t restore NTFS permissions for folders during extracting from WIM archives.
The BUG was fixed:
The command line version: if the command "rn" (Rename) was called with more
than one pair of paths, 7-Zip used only first rename pair.
Some bugs were fixed.
