If you use Snapchat regularly, you'll want to check out the new 6.1 update which includes new smart filters, special text, and a best friends feature that lets you put up to seven friends in a favorites category of sorts.
The new features aren't anything to write home about but for regular Snapchat users, at least you can add new filters?
All the new features are off by default so in order to enable and start using them, just update the app then hop into settings and then manage. Enable what you'd like and you're good to go. If any regular Snapchat users have grabbed the update, let us know what you think in the comments. I'm not quite understanding what the smart filters feature actually does, so if you figure it out, let us know!
