As Girish Indicated, and is indicated within our release announcement. The result of the delay is on MS not dropping the patches at the same time. The team picked up the patches when MS delivered them, and started work. I understand this may be an impact to your ongoing operations, I understand this is not optimal, but we are reflecting the latency from MS here and we are trying to relay our observations through the release notes. We need to follow the same QA procedures for the new patches so unfortunately this pressed the timeframe back for the affected patches.
