=== Querying for revisions of entity including property names that were modified
|
||||||
|
|
||||||
|
[NOTE]
|
||||||
|
====
|
||||||
|
This feature described here is still considered experimental.
|
||||||
|
It is subject to change in future releases based on user feedback to improve its usefulness.
|
||||||
|
====
|
||||||
|
|
||||||
|
Sometimes it may be useful to query entity revisions and also determine all the properties of that revision which
|
||||||
|
were modified without having to issue multiple queries using `hasChanged()` and `hasNotChanged()` criteria.
|
||||||
|
|
||||||
|
You can now obtain this information easily by using the following query:
|
||||||
|
|
||||||
|
.Querying entity revisions including property names modified.
