Fix: Added a nonce to the Dropbox deauth link. This is a minor security issue – someone personally targeting you, who knew that you were logged in to your WordPress admin, and who could persuade you to visit a personally-crafted web page, could cause the connection between UpdraftPlus and your Dropbox to be broken. The only impact of this is that the sending of your next backup to Dropbox would fail, and you would be alerted about the need to re-connect.
Fix: Import settings now handle the new remote storage options format
Tweak: Added a version check when saving settings to prevent errors or lost settings
Tweak: ‘Existing Backups’ table now shows an icon for each remote destination that the backup was sent to
