PeaZip 11.0: archiver updates for Linux and Windows

# PeaZip 11.0: New Features in the Cross-Platform Archiver for Developers

The cross-platform archiver PeaZip 11.0, written in Pascal using Lazarus/FreePascal, was released on April 6, 2026. This version incorporates improvements from the 10.x series, speeds up archive browsing, adds drag-and-drop support for tabs and the navigation panel, alternative icon styles, and batch testing. The Pea 1.30 and 7z/p7zip 26.00 backends ensure compatibility with 242 formats, including compound archives and encryption.

Key Technical Updates

PeaZip 11.0 compiles with Lazarus 4.2, maintaining compatibility with versions 2.x and 3.x. The Pea/Unpea graphical interface has been updated thanks to Pea 1.30. Archive browsing performance has been improved through rendering optimization and fractional scaling. Drag-and-drop now works with tabs and the navigation panel, simplifying navigation in multi-level structures.

Support for alternative icon display styles allows customizing the UI for different work environments. Added batch testing of archive integrity and password entropy evaluation—useful for automating tasks in CI/CD pipelines.

The CLI interface has been expanded for scripting: backward compatibility with previous syntax is preserved, and options for handling compound archives (001, r01, z01) have been added. Localization in 30 languages, including Russian, does not affect technical strings.

Fixed Bugs and Errors

Developers have fixed key issues affecting stability:

• Bug with automatic password prompt for encrypted ARC files.
• Icon mismatches in bookmarks, session history, and tabs.
• Failure to save navigation chain during forced archive refresh.
• Incorrect translation of special folder names in bookmarks.
• Prevented simultaneous auto-open tar events in compressed tar.* archives without reopening.

These fixes ensure predictable behavior in production scenarios, especially when handling large archives.

Supported Formats and Standards

PeaZip 11.0 opens 242 extensions: 7z, ace, arc, bz2, cab, gz, iso, paq, pea, rar, tar, wim, zip, zipx, and others. Support for compound archives simplifies working with split files. Multiple encryption standards (AES, Twofish) and hashing (CRC32, SHA) are integrated into the GUI and CLI.

For developers, password authentication via entropy is relevant—it allows scripts to check strength before archiving. Integration with InnoSetup for Windows builds maintains portability.
