Agile Web Solutions today announced 1Password 3 is officially out of beta and available for sale. The upgrade offers several new features, an upgraded (and better) interface, and full 64-bit support for Snow Leopard.

I’ve been in the beta for quite awhile and appreciate the many changes and UI refinements. It feels more like a Mac app now than ever before.

Users can also now organize their software licenses in a new, dedicated 1Password Vault category, customize exactly what information syncs to 1Password touch on an iPhone or iPod touch, attach and encrypt virtually any file in 1Password, use Smart Search to filter for just the right results, use tags throughout 1Password for new organizational power, edit 1Password items directly from its browser extensions, and more. For months the beta builds have been rock solid.

It is a paid upgrade, though users who purchased 1Password 2 on or after February 1, 2009 get free license upgrades to version 3. All other owners of 1Password versions 1 or 2 can take advantage of a limited-time, Early Bird Upgrade Discount. Through the end of November, save 50% off the purchase of a single license upgrade at $19.95 USD, or save 57% off a Family Pack upgrade of five licenses for just $29.95. Full licenses cost $39.95 for single users, and $69.95 for Family Packs.
