This is a reminder that the legacy Open Calais API will be retired tomorrow, September 30, 2015 in favor of a new and improved service. The new and improved service offers many advantages, such as enhanced through-put and metadata capabilities.
The new service is not fully backward compatible with the legacy Open Calais and will require a few manual changes on your end. However, we have defined a workflow to ensure a smooth transition to the new service. That workflow can be found here.
In order to avoid a disruption of service, it is important that you make the necessary changes on your end TODAY.
Thank you for being part of the Open Calais community.
