New features

Important

The following changes affect default behavior. If you rely on the previous behavior, review these changes before upgrading.

  • NoObj cache is now enabled by default. This changes the default behavior from previous versions.

  • Objects ending with `/` are now recognized as folders by default. This changes the default behavior from previous versions.

Optimizations

  • Improved performance in direct read mode.

  • Improved performance for concurrent read and write operations on small files.

  • Optimized memory usage in direct read mode.

Stability and experience optimizations

  • A terminal prompt now appears after a successful mount.

    Note

    The prompt recommends using the V4 signature method. Switch to V4 signatures if you have not already done so.

  • Fixed a read error that could occur when mounting as a RAM user with the use_cache parameter enabled.

  • Improved error message display.
