On July 26, 2015 we will be installing an update to the WMS Collection Management API. This update will include a fix for the caption and enumeration bug outlined in our blog post of May 2015.
Additionally we will be updating the output for the single copy response so that is a single Atom entry and conforms to our standards for web services. This is to remedy a bug that was introduced earlier this year that wrapped a single copy in an Atom feed. The new output will fix the bug and revert the response to a single Atom entry.
Please let us know, if you have any questions about this update.
