Urgency: not immediate - but it could impact some sites as soon as June,

depend on visible signs of Extended Validation, that will be impacted
almost immediately.

Impact: Chrome will start distrusting Symantec certs (as well as Thawte,
Verisign, and other CA properties owned by Symantec) on a graduated
timeline, depending on age and duration of cert. They will also stop
showing visible signs of Extended Validation (EV) certs immediately.

Google announcement and discussion:


Good summary of the practical upshot, with timelines:

I also have a feature request in with Qualys to add this to the SSL Labs
Server Test
