We are currently in the process of deploying a new version of openrouteservice onto the servers, and so there may be some slight changes. When the new version is fully deployed, we will make a post about the most important changes. Until then, if you notice any issues when calling the API, check the ChangeLog to see if something was modified in the newer version.
As always, if there are any issues feel free to post a message and we will do our best to help.
