v3.1.2.1

After extensive testing and a lot of time in open and closed beta we are marking this version as stable.

v3.1.1.2-beta

This version uses a slightly different data file format that allows for simpler code and faster detection when dealing with useragent strings that are a subset of other useragent strings. See the ReadMe for more info.
