Update

18.00 beta 2018-01-10
-------------------------
- 7-Zip now can unpack OBJ/COFF files.
- new -sse switch to stop archive creating, if 7-Zip can't open some input file.
- Some bugs were fixed.


17.01 beta 2017-08-28
-------------------------
- Minor speed optimization for LZMA2 (xz and 7z) multi-threading compression.
7-Zip now uses additional memory buffers for multi-block LZMA2 compression.
CPU utilization was slightly improved.
- 7-zip now creates multi-block xz archives by default. Block size can be
specified with -ms[Size]{m|g} switch.
- xz decoder now can unpack random block from multi-block xz archives.
7-Zip File Manager now can open nested multi-block xz archives
(for example, image.iso.xz) without full unpacking of xz archive.
- 7-Zip now can create zip archives from stdin to stdout.
- 7-Zip command line: @listfile now doesn't work after -- switch.
Use -i@listfile before -- switch instead.
- The BUGs were fixed:
7-Zip could add unrequired alternate file streams to WIM archives,
for commands that contain filename wildcards and -sns switch.
7-Zip 17.00 beta crashed for commands that write anti-item to 7z archive.
7-Zip 17.00 beta ignored "Use large memory pages" option.


17.00 beta 2017-04-29
-------------------------
- ZIP unpacking code was improved.
- 7-Zip now reserves file space before writing to file (for extraction from archive).
It can reduce file fragmentation.
- Some bugs were fixed. 7-Zip could crash in some cases.
- Internal changes in code.


16.04 2016-10-04
-------------------------
- The bug was fixed: 7-Zip 16.03 exe installer under Vista didn't create
links in Start / Programs menu.
- Some bugs were fixed in RAR code.

-------------------------

- The speed for single-thread LZMA/LZMA2 decoding
was increased by 30% in x64 version and by 3% in x86 version.

- 7-Zip now can use multi-threading for 7z/LZMA2 decoding,
if there are multiple independent data chunks in LZMA2 stream.

if there are multiple blocks in xz stream.

- New localization: Kabyle.

- Some bugs were fixed.

7-Zip v23.00 (BeTa) Was Released
HISTORY of the 7-Zip v23.00 2023-05-07:
- 7-Zip now can use new ARM64 filter for compression to 7z and xz archives.
ARM64 filter can increase compression ratio for data containing executable
files compiled for ARM64 (AArch64) architecture.
Also 7-Zip now parses executable files (that have exe and dll filename extensions)
before compressing, and it selects appropriate filter for each parsed file:
- BCJ or BCJ2 filter for x86 executable files,
- ARM64 filter for ARM64 executable files.
Previous versions by default used x86 filter BCJ or BCJ2 for all exe/dll files.
- Default section size for BCJ2 filter was changed from 64 MiB to 240 MiB.
It can increase compression ratio for executable files larger than 64 MiB.
- UDF: support was improved.
- cpio: support for hard links.
- Some changes and optimizations in WIM creation code.
- When new 7-Zip creates multivolume archive, 7-Zip keeps in open state
only volumes that still can be changed. Previous versions kept all volumes
in open state until the end of the archive creation.
- 7-Zip for Linux and macOS now can reduce the number of simultaneously open files,
when 7-Zip opens, extracts or creates multivolume archive. It allows to avoid
the failures for cases with big number of volumes, bacause there is a limitation
for number of open files allowed for a single program in Linux and macOS.
- There are optimizations in code for 7-Zip's context menu in Explorer:
the speed of preparing of the menu showing was improved for cases when big number of
files were selected by external program for context menu that contains 7-Zip menu commands.
- There are changes in code for the drag-and-drop operations to and from 7-Zip File Manager.
And the drag-and-drop operation with right button of mouse now is supported for some cases.
- The bugs were fixed:
- ZIP archives: if multithreaded zip compression was performed with more than one
file to stdout stream (-so switch), 7-zip didn't write "data descriptor" for some files.
- ext4 archives: 7-Zip couldn't correctly extract symbolic link to directory from ext4 archives.
- HFS and APFS archives: 7-Zip incorrectly decoded uncompressed blocks (64 KiB) in compressed forks.
- Some another bugs were fixed.
