Chrome Version 66.0.3359.117 update available now
The biggest change is that Google Chrome will start showing SSL certificate errors for all Symantec certs issued before June 1, 2016, And autoplaying content with sound is now blocked by default.

Then in October, sites visited with Chrome 70 that don’t have HTTPS certificates will trigger a red “Not secure” label when entering text.
