7-zip32.dll/7-zip64.dll/7z.dll文字化け対策版 Ver.25.01.00.01を公開しました。

○Ver.25.01.00.01 – 2025/10/11
・7-Zip 25.01をベースにビルド。

25.00から25.01の更新内容は下記のとおり。

25.01          2025-08-03
-------------------------
- 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.


25.00          2025-07-05
-------------------------
- 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.
- fixed some bugs and vulnerabilities.
- 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.

○Ver.24.09.00.01 – 2025/02/09
・7-Zip 24.09をベースにビルド。

24.08から24.09の更新内容は下記のとおり。

24.09          2024-11-29
-------------------------
- 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.

○Ver.24.08.00.01 – 2024/8/21
・7-Zip 24.08をベースにビルド。

24.07から24.08の更新内容は下記のとおり。

24.08          2024-08-11
-------------------------
- 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.
