This is a minor release containing an important change required in automated upgrade scenarios.
When the upgraded scheme contains one or more properties that don’t exist on the old system, deploying a XoomXML from the old system would previously cause those properties’ values to be deleted. The behaviour has been changed in this release, and those properties will now keep the value they already have in the updated system. This avoids the need to pre-populate the XoomXML file with up-to-date data prior to deployment in such scenarios, which is a cumbersome and time consuming step.
We are not currently aware of any situations where this change is undesirable since persistent differences in the scheme only ever happen in upgrade scenarios.
