As you probably know, I’m a fan of BitTorrent Sync. When it comes to fast file sharing, there are a few really good options (that almost all trump Dropbox for me), and Sync is one of the best. I’ve been beta testing version 2.0 and am excited to announce that it’s stable and available today!

The core features of Sync are available for free. There’s a new “Pro” tier, which is enabled for free for the first 30 days, which enables some cool extra features.

Sync 2.0 does everything that the last version (1.4) did, but with a better interface, an enhanced security model, and a cool “selective sync” (a “Pro” feature) that allows you to connect to a shared folder without downloading its contents. Instead, you get placeholders, and double-clicking a file (or tapping on iOS) will download just that file and keep it in sync.

If you own a NAS, Sync 2.0 also has an expanded list of devices (Seagate, Western Digital, NETGEAR, Synology, Drobo, Asustor, QNAP, Overland) that it can integrate with.

Sync 2.0 works with Mac, Windows, Linux, and FreeBSD. The mobile updates for iOS, Android, Windows Phone, and Amazon Kindle will also be released today. There’s a fun intro video to check out, an announcement blog post, and you can check out Sync 2.0 itself at GetSync.com.
