I forgot to mention one important update to the API in our last newsletter.
* Changed: API – The Keywords field in the Submission Edit interface is no longer required. Previously you had to send all of a submission's current keywords via the keywords field when you were updating any other detail on the submission, which was a bit silly. Now if you omit the keywords property entirely when sending changes it will leave the keywords as they are. If you send the property but leave its value blank (empty string) it will clear all the keywords on the submission. To add/remove keywords you need to send an entire new comma-separated keywords string for the submission. Don't forget to join multi-word keywords using underscores!
