It has been posted in the Preview Early Access Group that due to critical issues found, the 10.0.41 GA date has been pushed back from September 13th to September 17th. This is tentative that no further issues are found. You will receive an update via LCS with the updated planned date.

You can contact support to get access to the First Release build to start validation activities to minimize the impact of the delay. Further updates on this can be monitored from the Yammer thread here.

As always, planned dates are kept up to date within the Service Update availability documentation here.
