Deprecated Classes

Class and Description
com.google.common.collect.ForwardingBlockingDeque This class has moved to com.google.common.util.concurrent. Please use ForwardingBlockingDeque instead.
com.google.common.collect.TreeTraverser Use Traverser instead. All instance methods have their equivalent on the result of Traverser.forTree(tree) where tree implements SuccessorsFunction, which has a similar API as TreeTraverser.children(T) or can be the same lambda function as passed into TreeTraverser.using(Function). This class is scheduled to be removed in October 2019.

For speed: Hashing.goodFastHash(int), though see its docs for caveats.

For speed: Hashing.goodFastHash(int), though see its docs for caveats.
