Hypothesis 1.3 is probably the first version of Hypothesis recognisable as its modern incarnation. Previously it had a really weird API based on using values to describe types. So e.g. the value [float] described a list of floats.

This was cute but turned out to be a terrible idea. Describing things with simple function calls turns out to be far superior to doing cute but highly inflexible things like this.
