CHANGELOG

What's New in version 7.4.1:

  • PeaZip 7.4.1 introduces GUI refresh and improves working with 7Z, ARC, PEA, RAR, and ZIPX archive types.
  • It is now possible to use new fast compression algorithms in 7Z format: Brotli, Fast-LZMA2, Lizard, LZ4, LZ5, and Zstandard are now available, providing faster-than-Deflate compression with better speed-to-compression-ratio efficiency.
  • PEA now supports multiple cascade encryption, i.e. AES+Twofish+Serpent, each 256 bit in EAX mode.
  • RAR archives are now fully read-write supported from PeaZip if Rar.exe is featured in the system: it is possible to update, edit, rename, and delete files in existing RAR archives, and more RAR-specific options are supported (set comment, lock archive, header encryption, set recovery records percentage).
  • ZIPX archives can now be edited, and it is possible to optionally use .zipx extension when creating non-Deflate compressed .zip archives.
  • It is now possible to repair ARC and RAR files, and even to attempt recovery if the archive cannot be opened for browsing.
  • A total of 210 file extensions can now be managed by PeaZip.
  • Translations are available in over than 30 languages, any help is welcome to translate PeaZip to new languages and to maintain current localizations up to date, so please consider taking the time to give a look to translations directory for newer language files and for any resource useful for translators.
