Today AgileBits released 1Password 4.2 for Mac, a big update to the popular password manager that brings over 30 new features and improvements. The bulk of the additions are actually for 1Password mini, the app’s browser extension for Safari, Chrome, Firefox, and Opera.

You can finally edit items directly in 1Password mini, which has been one of the app’s biggest feature requests from users. There are a lot of other improvements included in the update, and AgileBits has commissioned Lonely Sandwich to make an awesome promo:

Back in December of last year, AgileBits released version 4 of 1Password for iOS. A completely redesigned, streamlined interface was introduced along with a built-in browser and iCloud syncing. The app has supported Dropbox and WiFi syncing for years, but iCloud was a welcomed addition when using version 4 on multiple iOS devices.

1Password 4.0 for iOS was a great release, but the Mac version was sadly left in the dust. The good news is that the developers at AgileBits have been working quietly on a totally new version of the Mac client for months, and it’s finally available.

1Password has been one of the most essential Mac apps for years, but it hasn’t seen a major upgrade since November 2009. Agile Bits is hard at work on the redesign of 1Password 4 for Mac, but they sent us a sneak peek of the reengineered password management app that’s been in the making for over a year.

Here’s what’s new:

AgileBits has announced today that 1Password 4 will be on sale for just $7.99 for a limited time. That’s 55% off its regular price tag, and the app’s cheapest price tag to date. But what’s the reason for the sale? Well, on September 1, Dropbox syncing will stop in 1Password 3 for iOS, and AgileBits wants you to upgrade to the latest version to keep this functionality.

AgileBits, creators of the popular 1Password tool for Mac and iOS, have today announced that 1Password 4 for Mac has entered beta. The release comes six months after 1Password 4 came to iOS, and you can get your hands on the early release by joining the AgileBits Beta Family.

1Password, the ultimate password manager for Mac and iOS from AgileBits, is now half price for a limited time on iOS. The discount comes just two weeks after the app was updated with a whole host of new features and improvements following user feedback.

Scheduled as a December 13th launch, 1Password, version 4.0.2, is available now on the iTunes App Store.

The updated app brings a host of new features, and is available for $7.99, which is 50 percent off the typical price of the security app from atebits software.

AgileBits has overhauled its 1Password app for iOS for version 4.0, and its begun teasing the release with a new trailer ahead of its December 13 launch. The video doesn’t give away any of 1Password’s new features, but it does show off its new look. Although you will have to keep your eyes peeled if you want to see it; blink and you’ll miss it.
