7-Zip 23.01: New Features for Faster Compression and Better Security

The latest version of 7-Zip, 23.01, brings several exciting features that enhance its compression capabilities and security standards. One of the notable improvements is in the way 7-Zip handles multivolume archives on Linux and macOS. Now, when you open, extract, or create a multivolume archive, 7-Zip can reduce the number of simultaneously open files, making the process more efficient.

When creating new multivolume archives, 7-Zip only keeps in open state volumes that are still changeable, reducing memory usage and improving overall performance. Additionally, there have been some changes and optimizations in the WIM creation code, which can lead to increased compression ratios for executable files larger than 64 MiB.

Another notable update is the default section size for BCJ2 filters, which has been changed from 64 MiB to 240 MiB. This change can result in better compression ratios for certain types of files. Furthermore, 7-Zip now uses a more specific filter approach when compressing executable files (exe and dll extensions). It parses these files before compression and selects the most suitable filter based on the file's architecture (x86 or ARM64).

The new ARM64 filter can significantly improve compression ratios for data containing executable files compiled for ARM64 (AArch64) architecture. Moreover, 7-Zip now supports using this new filter when compressing to 7z and xz archives.

In addition to these technical updates, 7-Zip has also improved its self-extracting capabilities for the 7z format, introduced strong AES-256 encryption in both 7z and ZIP formats, and achieved better compression ratios (2-10%) compared to PKZip and WinZip for ZIP and GZIP formats. The high compression ratio of 7z format with LZMA compression remains unchanged, making it an excellent choice for users seeking a reliable and efficient archiving solution.

Overall, the latest version of 7-Zip offers numerous enhancements that can streamline your archiving tasks while maintaining top-notch security standards. Whether you're working on Linux, macOS, or Windows, 7-Zip 23.01 is definitely worth considering.
