Release Highlights

Aspose.ZIP for .NET 25.5 DLLs bring greater compression flexibility and legacy format support, including .tar.lz4 creation and uuencode detection, along with efficiency gains and bug fixes.

✳️ New Feature

• Detect Uuencoded Files by Signature:

  • Adds the ability to recognize and process uuencoded files without requiring format-specific flags.

• TAR with LZ4 Output:

  • Compose compressed .tar.lz4 archives using TarArchive.SaveLZ4Compressed().

🔧 Enhancement

• Configurable LZ4 Archive Properties:

  • IncludeContentSize: Controls whether the archive frame stores the uncompressed size.
  • IncludeBlockChecksum: Adds a checksum per block to ensure data integrity.

• Efficient LZ4 Decompression:

  • Memory use during LZ4 archive extraction is optimized for improved speed and lower system load.

• Unix File Mode Support:

  • Uuencoded files and other entries now retain Unix permissions for accurate file restoration across platforms.

🛠 Fix

• Unix Mode Handling Fix:
  • Corrected an issue where file mode was not applied on Unix systems if the archive was missing file metadata explicitly.
