/stopcasting 2.3 lag workaround

Hi. I was wondering if there has been any update to this since it was announced a couple of months ago?

Q u o t e:
FYI, we're working on something for 2.3 to help make /stopcasting lag workarounds unnecessary.

Playing from the UK with an average of 500 latency, it is the thing that I have been looking forward to the most about 2.3.

Thanks!
