What has happened to the 6.37 patch

Overlord: I do understand that my replies, especially with dates, are regarded as official information, but it needs to be pointed out, the dates posted on the forums are rough, they reflect internal schedule and are meant to give only general understaning of projected time lines. Until the respective announcement appears on the website, it is not totally confirmed.
Guess, it was the last time I allowed myself to post a preliminary date. Sorry for disturbance everyone.
0.6.3.8 patch will include all changes from 0.6.3.x series plus some more.
