New Update:23.03.2024

- 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 '\'.

New Update:14.05.2024

- 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.

New Update:11.08.2024

HISTORY of the 7-Zip v24.07

- The bug in 7-Zip 24.00-24.08 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.

7-Zip v24.09

New Update:29.11.2024

HISTORY of the 7-Zip 24.09

- 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.
