Thanks to those of who have made the upgrade to the new Open Calais. We hope that you are experiencing the many advantages of doing so.
For those users who have not yet made the upgrade, we urge you to do so at your earliest convenience, as the legacy system you are currently using will be shut down August 31, 2015.
Please visit our Upgrade page here for more information on the upgrade and to download the Upgrade API User Guide.
As always, we’re here to help. For any questions, please email us at firstname.lastname@example.org.
