Targeting 3.2 from now on
As the title says, from now on I will only be targetting Movable Type version 3.2 or later. I will only be testing with that version and I cannot guarantee my plugins will work in any version prior. Testing the 3.1x versions (or even earlier) would just be too time consuming to be worth my effort. That is not to say that I will not backport my plugins to MT 3.1x or earlier, but unless you plan on paying for the effort, 3.2 is it.
