In early 2017, Google and other browser vendors are planning on deprecating support for SHA-1 certificates. This has potential to introduce new warnings or impact to legacy and current products using SHA-1 certificates.
For more information, please review the following resources:
Timeframe: Jan-March 2017
Chrome will have an optional policy setting to allow trust of SHA-1
Timeframe: January 2017
Firefox will show an overridable "Untrusted Connection" error

"There will be no impact for roots that are not included in Microsoft Trusted Root Program, such as enterprise or self-signed roots that you’ve chosen to trust"
We encourage everyone to secure their systems as a matter of priority.
