Hi!

Official v4.1.3.9045 version is works correctly.

But with this snapshot build (downloaded with built in updater): v4.1.4 9177, if I upload any file to Amazon S3, I get error message: "The Encryption request you specified is not valid. Supported value: AES256."

And my suggest: Good idea, if Amazon S3 server side encryption selectable in options (preferences/S3)

Log:
