Chrome 41 was released on March 3, 2015. You may have noticed, Chrome 41 did not have a change to treat certificate chains using SHA-1 valid past January 1, 2017 to be affirmatively insecure.
The affirmatively insecure representation will now occur in Chrome 42. We expect Chrome 42 to be released about April 14, 2015.
We continue to highly recommend that all users of SHA-1 signed SSL certificates which expire after 2015 to renew these certificates signed with SHA-2. This will remove warning messages to the users of your website. It will also prepare your site for the full SHA-1 deprecation scheduled for 2017.
Please visit our website for more information on migration from SHA-1 to SHA-2.
