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.
What's new in 7-Zip 25.00
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%.
