It's also good to see that they've scrapped the old way of only increasing in multiples of 5/10% for the 0.5.5 bar (note that it says 0.5.5, not 0.5.1).
I was kind of hoping that they'd put the Blue bar up by more than 5% though because people will say "OMG 6 months for 5%. That means Blue will be out in 3 years' time."
Of course, some features take longer to implement than others and hence it is not possible to use the bars to predict release dates.
