Hello! I had read that there would have been a few major updates with bugfixes on day 1 after release. Has this already happened?

The only updates I've received besides definition updates and drivers are:

Code:
Security Update for Windows 10 for x64-based Systems (KB3074683)
Update for Windows 10 for x64-based Systems (KB3074678)
Update for Windows 10 for x64-based Systems (KB3074686)
Should I have received some other update as of today?
