I do not think it is a joke. They intend to follow a release schedule, for sure, but obviously since bug discovery continues and we, users, keep on sending them new requests, well, what do you expect?

I much prefer delays due to security checks, bug fixes and enhancements than a zillion betas and RCs that will result in more work on my own site. It is frustrating, but for them too. If only more software companies had an OPEN forum for their customers to help out tweaking their products....

Anyways, see more let's focus on making the next release the best it can be.
