|Block/Unblock Worker||New operations allow you to block and unblock a Worker from doing work on your HITs without using Qualifications.|
|Change the HIT Type of a HIT||You can change the HIT Type of your HITs by using the ChangeHITTypeOfHIT. This will allow you change properties like reward, title, description, etc. on HITs that are already in the production system. There are some limitations which are fully documented in the developer guide.|
|Enumeration sort property||A new sort property Enumeration returns HITs reliably and with no duplicates. This directly impacts SearchHITs and GetReviewableHITs by addressing the current limitations of those operations.|
|MTURK-2733||Cannot disable retry delay for a Qualification type once enabled.||There is currently no way to disable the ability to re-request a Qualification if the Qualification type allows retries. A previous release introduced the ability to add a retry delay to a type that doesn't have one, or modify the delay if it does. Once a type has a retry delay, then retries are permanently enabled for the type.|
|MTURK-3629||Cannot remove a test from a Qualification type.||There is currently no way to remove a Qualification test from a Qualification type that has one. A previous release introduced the ability to configure a Qualification type to automatically approve Qualification requests instead of using a Qualification test. Because tests cannot be removed from an existing type, a Qualification type with a test cannot be re-configured to use the auto-approval feature.|
|MTURK-2856||SearchHITs can include duplicate HITs in results.||The SearchHITs API may return a HIT more than once in the results if there are more than 100 active HITs created by the caller when using a sort property other than Enumeration.|
|MTURK-2034||Incorrect number returned for TotalNumResults response element of GetReviewableHITs.||GetReviewableHITs does not reliably return the correct number for the TotalNumResults response element.|
