Instagram v2.1 gets a new and improved user interface and includes a number of new features such as Lux – a photo enhancement feature, a new filter called Sierra and improved iOS Notification Center integration.
Instagram has explained a bit more about the new features on their blog:
We’ve given you a new way to instantly transform the look and feel of your photos. In just one tap, Lux works its magic by making your photos more vibrant and bringing out details you couldn’t see before. Use it with a filter or without.
Simplified + Improved UI
We’ve simplified the look of Instagram. The improved header and menu buttons in this release are the first steps towards making it easier to understand and interact with our app.
Now, when you tap on an Instagram notification in the iOS Notification Center, you’re brought directly to the relevant photo, comment or user profile page in the app.
You can check out the image below before and after using the ‘Lux’ photo enhancement feature. It’s quite similar to Camera+’s popular ‘Clarify’ feature.
You can download Instagram 2.1 using this App Store link for free or update it via the Updates Tab in the App Store app.
