It seems 1.3.3 is silently out of RC’s and it’s been released out into the wild!
Nice! I think it’s quite early to call it silently released though. If it was to be announced would it in any case first be when it hit the “recommended version”.
Also, notice that as long as it has to be installed with
meteor update --release 1.3.3 will e.g. the node and npm version not be updated automaticlaly.
