Here is a more complete rundown of the new features:
- Huge performance enhancements: the client-side sync engine has been re-architected to optimize the response time, scale, and resource consumption. As a result, memory usage has been reduced by up to 50 percent. Big changes made to Dropbox are now more efficient and smaller changes remain quick.
- Better user experience: the initial setup wizard has been redesigned to make it easier to get started using Dropbox. The Mac OS X version has been rewritten to only use Cocoa, bringing down the Mac download size by 20 percent.
- Selective Sync: you now can choose which folders get downloaded to which computers, so you don't have to sync stuff you don't need.
- Extended Attribute Sync: resource forks and other extended attributes are now supported. Resource forks are an area of a file that certain applications use to store important data, and that most sync programs today completely ignore, which results in a corrupted file on the other end.
"1.0 is a milestone for us, and with it we want to communicate our confidence that Dropbox is stable, high-quality software," a Dropbox spokesperson said in a statement. "The service has grown from a simple sync app to something that's changed the way lots of people work and communicate. But just because this version of Dropbox has a new number doesn't mean that we're anywhere close to finished. We have a long way to go before we realize our goal of making it easy for everyone to always have access to their stuff."
