🆕 Version 3.x

• 3.2

  • 📦 Safer ZIP creation and finalization
    • Upload completion is only reported after the ZIP process has finished successfully
    • Added final checks to ensure the ZIP archive exists, is readable and is not empty before creating the download link
    • ZIP and filesystem errors now return proper HTTP error responses and clean up temporary data
    • Added free-space checks for both uploaded files and the final ZIP archive
  • 🔒 Upload security improvements
    • Added strict validation for upload IDs, relative paths, file sizes, file counts and upload modes
    • Prevented directory traversal and invalid control characters in uploaded paths
    • Added safer host and URL handling when generating download and verification links
    • Escaped uploaded filenames in the browser to prevent HTML injection
  • 💾 Safer metadata storage

    • Improved metadata validation and error handling for save and cleanup requests
  • 🖥️ Improved browser upload handling
    • HTTP and server errors are no longer hidden or displayed as successful uploads
    • Upload controls are restored after an error so the upload can be retried without reloading the page

    • Folder paths and file metadata are preserved more reliably during drag-and-drop uploads
• 3.1

    • Perfect for teams, client areas or project-based uploads
    • Password protection, expiration times, link creation and download continue to work as usual

    • The default configuration is now automatically completed and merged with any missing keys when config.php is loaded

• 2.9
  • 👁️ Added a new “Show Download Page” toggle (show_dp) in the configuration
  • 🔗 Lets you choose whether users see a download page (file info and download-button) or a direct file download after clicking the link
  • 🛠️ Fully integrated into the Admin Panel configuration and stored in the main config.php file
• 2.8
  • 📧 Added support for a separate SMTP FROM address (SMTP_FROM_ADDRESS) so the visible sender can differ from the SMTP login (same domain required)
  • 🛠️ Reworked SMTP sending to be RFC-compliant (adds Date, Message-ID, MIME-Version, multipart text/plain + text/html, UTF-8 encoded subject) for better compatibility with spam filters
  • 🖥️ Admin Panel extended with a new field to configure the SMTP FROM address, which is stored in the .env file
  • 🗂️ Improved Docker support for persistent configuration: the entire inc directory (including .env, .admin.json, config.php, translation files) can now be mounted from the host
  • 💾 Upload directory can now also be mounted externally via DROPZONE_UPLOAD_DIR, making all uploaded files persistent and safe across container updates or reinstallation
  • 📦 When mounting an empty inc directory, Dropzone automatically initializes it with the default files from the image, ensuring a clean setup when the container is recreated
  • 🔄 This means both all settings (SMTP, admin login, configuration options) and all uploaded files are preserved even if the container is removed and recreated
