The deprecated `binResultsDir` property of the `AbstractTestTask` task type has been removed.
Use the `binaryResultsDirectory` property instead.

==== SourceDirectorySet API Cleanup

The deprecated `outputDir` property of the `SourceDirectorySet` type has been removed.
Use the `destinationDirectory` property instead.
