This attribute was used mostly to determine when database objects were last changed, but in practice the attribute was poorly maintained. We are now in the process of replacing the “changed:” attribute by the server-generated attributes “created:” and “last-modified”.

However, contrary to the earlier plan communicated on this, we will not reject object updates if they include the “changed:” attribute. Instead, we will remove the “changed:” attribute from the object and issue a warning, but accept the remaining object (provided it passed other validation rules). The reason for this is that we still see a large number of updates that include the “changed:” attribute. We expect this number to go down over time when the “changed:” attribute is removed from the object templates, and when the attribute is no longer present on objects that are being updated. We will monitor this carefully over the coming months before implementing stricter regulations concerning the attribute.

No issues have been reported so far. If no issues are found over the coming two weeks, it is our intention to deploy this release to production on Monday, 1 February.
