7-Zip: descargar versiones anteriores

- Improved code for unpacking Z archives and Mach-O files.
- Some bugs and vulnerabilities were fixed.

- Some bugs and vulnerabilities were fixed.

- Some bugs and vulnerabilities were fixed.
- CVE-2026-58052 : 7-Zip failed to preserve the Mark-of-the-Web when extracting a crafted archive.

- Some bugs and vulnerabilities were fixed.

- 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 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.

- improved code for ZIP, CPIO, RAR, UFD, QCOW, Compound.
- 7-Zip File Manager: improved sorting order of the file list. It uses file name as secondary sorting key.
- 7-Zip File Manager: improved Benchmark to support systems with more than 64 CPU threads.
- the bug was fixed: 7-Zip could not correctly extract TAR archives containing sparse files.
- some bugs were fixed.

- CVE-2025-55188 : The code for handling symbolic links has been changed
to provide greater security when extracting files from archives.
Command line switch -snld20 can be used to bypass default security
checks when creating symbolic links.

- 7-Zip for Windows can now use more than 64 CPU threads for compression to zip/7z/xz archives and for the 7-Zip benchmark. If there are more than one processor group in Windows (on systems with more than 64 cpu threads), 7-Zip distributes running CPU threads across different processor groups.
- bzip2 compression speed was increased by 15-40%.
- deflate (zip/gz) compression speed was increased by 1-3%.
- improved support for zip, cpio and fat archives.

- CVE-2025-11001 and CVE-2025-11002 : A vulnerability was fixed for symbolic links processing, when extracting files from archives.
- the bug was fixed : CVE-2025-53816 : 7-Zip could work incorrectly for some incorrect RAR archives.
- the bug was fixed : CVE-2025-53817 : 7-Zip could crash for some incorrect COM (Compound File) archives.

- The default dictionary size values for LZMA/LZMA2 compression methods were increased:
dictionary size compression level
v24.08 v24.09 v24.09
32-bit 64-bit
8 MB 16 MB 16 MB -mx4
16 MB 32 MB 32 MB -mx5 : Normal
32 MB 64 MB 64 MB -mx6
32 MB 64 MB 128 MB -mx7 : Maximum
64 MB 64 MB 256 MB -mx8
64 MB 64 MB 256 MB -mx9 : Ultra
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.

- The bug was fixed: 7-Zip could crash for some incorrect ZSTD archives (CVE-2024-11477).

- The bug was fixed: 7-Zip could not unpack some ZSTD archives.

- 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.

- The page "Language" in 7-Zip's menu Tools/Options now shows information about selected translation, including the number of translated lines.
- Some bugs were fixed.

- 7-Zip now can extract APFS (Apple File System) images that can be used in DMG files.
- 7-Zip now can create TAR archives in POSIX (pax) tar format with the switches
-ttar -mm=pax or -ttar -mm=posix
- 7-Zip now can store additional file timestamps with high precision (1 ns in Linux)
in tar/pax archives with the following switches:
-ttar -mm=pax -mtp=3 -mtc -mta
- New switches for Linux version for TAR archives:
-snoi : store owner/group ids in archive or set owner/group ids from archive to extracted files.
-snon : store owner/group names in archive
- New -snz switch to propagate Zone.Identifier stream to extracted files (Windows).
- New option "Propagate Zone.Id stream" in Tools/Options/7-Zip menu.
- New "Options" window in "Add to archive" allows to select what metadata must be
included to archive. Also it allows to select new option
"Do not change source files last access time".
- Some bugs were fixed.

- 7-Zip now can extract VHDX disk images (Microsoft Hyper-V Virtual Hard Disk v2 format).
- New switches: -spm and -im!{file_path} to exclude directories from processing
for specified paths that don't contain path separator character at the end of path.
- In the "Add to Archive" window, now it is allowed to use -m prefix for "Parameters"
field as in command line: -mparam.
- The sorting order of files in archives was slightly changed to be more consistent
for cases where the name of some directory is the same as the prefix part of the name
of another directory or file.
- TAR archives created by 7-Zip now are more consistent with archives created by GNU TAR program.

- The window "Add to Archive" now allows to set a limit on memory usage (RAM)
that will be used for compressing.
- New switch -mmemuse={N}g / -mmemuse=p{N} to set a limit on memory usage (RAM)
for compressing and decompressing.

7-Zip didn't set attributes of directories during archive extracting.

- The speed for LZMA/LZMA2 compressing was increased
by 8% for fastest/fast compression levels and
by 3% for normal/maximum compression levels.
- 7-Zip now shows Properties (Info) window and CRC/SHA results window
as "list view" window instead of "message box" window.
- Some improvements in zip, hfs and dmg code.
- Previous versions of 7-Zip could work incorrectly in "Large memory pages" mode in
