Today these new features to its :

• Passwords for shared links create an additional layer of security so only people with the password can access your link.
• Expirations for shared links safeguard your sensitive files by letting you set how long your links stay up.
• View-only permissions for shared folders let you pick whether recipients can edit or just view files within your shared folder.
• Remote wipe lets you delete your Dropbox files from a lost or stolen device while keeping them safely backed up in Dropbox.

This announcement comes together with the simplification of storage plans. For USD 9.99 a month or USD 99.00 a year, all Pro users can now avail of 1TB of storage. 

The feature set is worth the upgrade, but the storage plan is still expensive for whoever needs less than 1TB of storage.

Obviously Dropbox has the metrics that show that only a handful of users are going to store 1TB of storage, hence this announcement masked as a price drop. A quick poll with my friends and colleagues has shown that all of them store way below 100GB of data in Dropbox. All these people will continue to pay USD 99.00.
