It's nice to see that 1.4.0 is released, but the Early Bird addition could use some work.
There is still no indication on the front end that you are getting an early bird rate, it just gives you the price. If I was a customer, I would just assume this is the regular price if the full price is not displayed anywhere.
Please add some kind of indication, preferably a second line under the regular price showing the early bird price, and when it is in effect until.
