could you please start including proper changelogs in your release notes on the Dropbox forum?
Beta testing makes no sense when the changelog states "bug fixes and improvements". That's also a common complaint of the people in the forum, which you're ignoring completely.
The best you can get is 'I will forward this to the team', but usually there is a wall of silence.
Please Dropbox, fix this, listen to your most valuable asset, paying users!
