Swiftkey Keyboard is not only received an update it's also dropping it's price to free. Swiftkey is considered one of the top 3 keyboards available for the Android OS and was totally worth the $2.99 price it carried. Now with the June 11th release of V5 it's not only better, it's also free.
Fantastic predictive ability, autocorrect that usually gets it right for me, a smooth swype experience and tons of customizations for the keyboard are the reasons Swiftkey is an award winning app. Some of the options are only available for Android 4.1 and above, but even on older versions the keyboard is worth having for the ease of use. I'm a personalization junkie, and Swiftkey has plenty of keyboard themes that fill my need.
The bonus to having paid for Swiftkey is that because they have changed the price to free, they are offering paid users a 10-pack of themes for free (cost of 10 pack is normally $4.99). Check out the screenshots to see how to redeem your 10 pack. If you've never tried Swiftkey this a great time to dive in. Although the stock Swype keyboard is useful, Swiftkey exceeds expectations.
