Dropbox today announced that it has reached 275 million users -- up from the 200 million it had in November 2013 -- and is releasing new apps for both personal and professional users.

The first announcement is that Dropbox for Business, which allows the company's users to keep their personal and professional files separate, is now available to everyone. The company has also created a new collaboration tool called Project Harmony that allows business users to see who else is editing a file, message each other while viewing documents, and more. Here's what the company has to say about the Dropbox for Business debut:

We’ve rebuilt the product to give users one Dropbox for personal stuff and another for work stuff. Users can easily access both Dropboxes from any of their devices.

We did this to give admins more visibility and control over their company’s data. Remote wipe helps protect confidential information, account transfer helps you maintain business continuity, and sharing audit logs let you track how your Dropbox for Business information is being accessed.

The second announcement is the release of a new app called Carousel, a mobile service that allows Dropbox users to upload photos to their accounts and have private conversations about them with their friends. The app is available on the iPhone and Android smartphones. The company explains the idea behind Carousel in its blog post:
Carousel sorts all these memories by event so you can easily travel back in time to any photo from any date. And unlike other mobile galleries, the size of your Carousel isn’t constrained by the space on your phone, which means you can finally have your entire life’s memories in one place.

We also think those memories are meant to be shared. That’s why we built private conversations into Carousel — as a way to relive entire events with friends and family. With Carousel, you can share hundreds of photos in the same amount of time it’d take to send just one by text. Even more, you can capture an event from every angle by saving the photos others share with you. The third announcement is that Mailbox, the email app Dropbox acquired last year, will be coming to Android smartphones and desktop computers. The app will also have a new "auto-swipe" feature that "learns from your swipes to get you closer to Inbox Zero." Basically: Mailbox will now automatically archive emails that it doesn't think you'll care about.

Dropbox co-founders Drew Houston and Arash Ferdowsi summarize today's announcements:

We started our journey seven years ago with Dropbox, a magic folder to keep your stuff safe. But as we’ve built Dropbox and seen how it’s helped millions around the world, that magic folder has become something much more — a home for life. At the company, we’ve been calling this Chapter 2. You have no idea how excited we are to show you what’s next.
