We are disabling support for SSL v3 because of a vulnerability identified earlier today. This means that if you are using SSL v3 in your code ie: curl_setopt($ch, CURLOPT_SSLVERSION, 3) in PHP then you will need to stop.  One option is to move to something more modern ie: TLS, another is to just remove this altogether.  If you have any issue with this please email me at: [email protected] and we will assist you.
