webfork wrote:7-zip has a CRC and SHA-256 checksum tool. It only functions in the file menu *outside* of archives, which is odd. Anyway, added note to entry.

Includes folder favorites, optional 2-pane view, checksum, available AES encryption, checksum calculator, file split/combine capability, and more.

I removed the redundant mention.

• Ultra simple mode (basic drag and drop window similar to that Mac program or Universal Extractor)
• Ability to encrypt using files as keys rather than passwords (PeaZip does this)
• Ability to cancel during transfer (sometimes this button works, sometimes it doesn't)
• Higher compression level profiles (highest possible selection on all lists) ... currently "Ultra" isn't the highest possible compression.
• Higher compression tool options (e.g. higher dictionary size, higher word size, etc.)
• Compression estimates (before compressing it gives an idea of how much space will be saved)
• Drag-and-drop profiles (e.g. create a box that lets you drag files into an area and have it save with a pre-determined output folder, as well as security and compression level)
• Low: Mac version (Mac is in desperate need of a file manager-based compression tool. The closest thing out there I've been able to find is muCommander)
• Very low: support for GPG

15.05 beta 2015-06-14
-------------------------
- 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.
- 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.
- The BUG was fixed:
7-Zip crashed for ZIP/LZMA/AES/AES-NI.
- The BUG in 15.01-15.02 was fixed:
7-Zip created incorrect ZIP archives, if ZipCrypto encryption was used.
7-Zip 9.20 can extract such incorrect ZIP archives.
- Some bugs were fixed.
