So glad to see 4.5 getting closer to the big day and here we are at the RC milestone. I have been playing with the betas for sometime now. I was pushing for actual project work on the betas as this release has the features, stability and performance in perfect mix.
Very recently I have done some client PoC work on the targetted beta and we had zero issues. Now that the RC is out we are going to go for the kill. RC will migrate to RTM so it is ideal for us.
You can download the installere from the K2 portal.
