7-Zip Release Notes

linux version of 7-Zip can use huge pages (2 MB pages). It can increase compression
speed for 10% for 7z/xz/LZMA/LZMA2 compression.

new -spo[d|c|r] switch specifies the path generation mode for the output directory
for archive extraction. The output directory path is generated from the path specified
in the -o{dir_path} switch and the name of the archive being unpacked.

-spod : for Linux/Posix/macOS: -o{dir_path} specifies the direct path to the output directory.
The asterisk (*) character in {dir_path} will not be replaced by the archive name.

-spoc : 7-Zip will concatenate the path specified in -o{dir_path} with the archive name
to form the final path to the output directory.

-spor : 7-Zip will replace asterisk (*) character in the path specified in the -o{dir_path}
with the archive name. This is the default option.

some bugs were fixed.

The default dictionary size values for LZMA/LZMA2 compression methods were increased:

The default dictionary size values for 32-bit versions of LZMA/LZMA2 don't exceed 64 MB.

7-Zip now can calculate the following hash checksums: SHA-512, SHA-384, SHA3-256 and MD5.

APM and HFS support was improved.

If an archive update operation uses a temporary archive folder and the archive is moved to the destination folder, 7-Zip shows the progress of moving the archive file, as this operation can take a long time if the archive is large.

The bug was fixed: 7-Zip File Manager didn't propagate Zone.Identifier stream for extracted files from nested archives (if there is open archive inside another open archive).

Some bugs were fixed.

The bug in 7-Zip 24.00-24.07 was fixed:
For creating a zip archive: 7-Zip could write extra zero bytes after the end of the archive,
if a file included to archive cannot be compressed to a size smaller than original.
The created zip archive is correct except for the useless zero bytes after the end of the archive.
When unpacking such a zip archive, 7-Zip displays a warning:
"WARNING: There are data after the end of archive".

The bug was fixed: there was a leak of GDI objects (internal resources in Windows)
in "Confirm File Replace" window, causing problems after 1600 displays of "Confirm File Replace"
window from same running 7-Zip process.

Some optimizations for displaying file icons in 7-Zip File Manager and in "Confirm File Replace" window.

Some bugs were fixed. CVE-2024-11612.

New switch -myv={MMNN} to set decoder compatibility version for 7z archive creating.

{MMNN} is 4-digit number that represents the version of 7-Zip without a dot.

If -myv={MMNN} switch is specified, 7-Zip will only use compression methods that can
be decoded by the specified version {MMNN} of 7-Zip and newer versions.

If -myv={MMNN} switch is not specified, -myv=2300 is used, and 7-Zip will only
use compression methods that can be decoded by 7-Zip 23.00 and newer versions.

New switch -myfa={FilterID} to allow 7-Zip to use the specified filter method for 7z archive creating.

New switch -myfd={FilterID} to disallow 7-Zip to use the specified filter method for 7z archive creating.

Some bugs were fixed.

7-Zip now can use new RISCV filter for compression to 7z and xz archives.
RISCV filter can increase compression ratio for data containing executable
files compiled for RISC-V architecture.

The speed for LZMA and LZMA2 decompression in ARM64 version for Windows
was increased by 20%-60%.

7-Zip GUI and 7-Zip File Manager can ask user permission to unpack RAR archives that
require big amount of memory, if the dictionary size in RAR archive is larger than 4 GB.

new switch -smemx{size}g : to set allowed memory usage limit for RAR archive unpacking.
RAR archives can use dictionary up 64 GB. Default allowed limit for RAR unpacking is 4 GB.

7zg.exe (7-Zip GUI): -y switch disables user requests and messages.

7-Zip shows hash methods XXH64 and BLAKE2sp in context menu.

-slmu switch : to show timestamps as UTC instead of LOCAL TIME.

-slsl switch : in console 7-Zip for Windows : to show file paths with
linux path separator slash '/' instead of backslash separator '\'.

7-Zip supports .sha256 files that use backslash path separator '\'.

Some bugs were fixed.
