Dropbox retiring its legacy API in favor of a next-generation one on September 1 is inevitably going to break apps which plan to continue syncing data through the popular cloud storage service using the legacy API.
Among them: AgileBits' 1Password 3 for iOS and Mac. Now, this rather useful password management utility has been using Dropbox to sync its secure database across devices for ages.
