Normally we will have longer beta evaluation periods, due to the relative impact of interface changes versus issues addressed we would like to fast track this release into production.</div><div><br></div><div>This release will not effect users of the DMC's Fetch family of scripts.</div><div><br></div><div>For those that have written code against the service please note the following changes:</div><div><br></div><div>- Service messages and errors are returned in a DMC standard format of type "text/plain", previously error messages were returned in a custom XML structure.</div><div><br></div><div>- The <SelectedNumberStations> and <SelectedNumberChannels> elements are now placed correctly in the document, this should not effect parsing but the documents should now validate against the schema.</div><div><br></div><div>- The Query parameter shortcut "chan" is deprecated. Please use query parameter "cha" or "channel" instead to specify channel codes(s).</div><div><br></div><div>- Empty elements (when value is null) are not included, e.g. no empty <Gain> elements.</div><div><br></div><div>- All <Station> elements will be contained within <Network> elements.</div><div><br></div><div>- Fixed the output of duplicate <Station> and <StationEpoch> elements.</div><div><br></div><div>- Fixed a bug affecting virtual networks where incorrect stations were returned.</div><div><br></div><div>- More validation of query parameters.</div><div><br></div><div>- Returned document contains reference to specific schema version.</div><div><br></div><div>This list of changes is documented here:</div><div><div><a href="http://www.iris.edu/wsbeta/doc/station_revisions.htm">http://www.iris.edu/wsbeta/doc/station_revisions.htm</a></div></div><div><br></div><div>regards,</div><div>IRIS DMC web services team</div></body></html>
