SharpZipLib v1.3.0 Release Notes

Release Date: 2020-10-07 // over 3 years ago

  • Highlights

    • 🛠 AES encryption fixes and support in FastZip
    • 👍 File name encoding support for Tar
    • 👌 Improved Unix timestamp support
    • 👍 Better handling of entry file names
    • 🛠 Fix errors with entries using Stored compression method

    🔄 Changes

    • TarArchive.ExtractContents() now needs another parameter set to true to allow the extraction to traverse outside of the target directory.
    • TarArchive constructors now includes an Encoding parameter. Omitting it will discard any non-ASCII bytes in file names.
