Fedora 6 behavior
Fedora 5 behavior
- Mementos can no longer be created by specifying a timestamp, and are always created on the current resource state at the current time.

- To perform a conditional PUT that works for both Fedora 5 and 6, use X-State-Token with X-If-State-Token instead.
Modifications to the same Resource in Separate Transactions
- If the same resource is modified in two different concurrent transactions, the first modification will succeed, but the second modification will fail with a 409 conflict with the following message: "Cannot update info:fedora/<id> because it is being updated by another transaction." This holds true for containers and binaries.
- In Fedora 5, both modifications would succeed, and whichever transaction committed last would be the final state of the object
GET Prefer return=minimal removed
