What's new after 7-Zip 9.38 Beta:

• 7-Zip now uses new installer.
• 7-Zip now can create 7z, xz and zip archives with 1536 MB dictionary for LZMA/LZMA2.
• 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.
