Changed Classes and Interfaces
ArrayListMultimap	Implementation of {@code Multimap} that uses an {@code ArrayList} to store the values for a given key.

FluentIterable	A discouraged (but not deprecated) precursor to Java's superior Stream library.
ForwardingBlockingDeque	A BlockingDeque which forwards all its method calls to another {@code BlockingDeque}.
ForwardingNavigableMap. StandardDescendingMap	A sensible implementation of NavigableMap.descendingMap in terms of the methods of this {@code NavigableMap}.
HashBiMap	A BiMap backed by two hash tables.
ImmutableBiMap	A BiMap whose contents will never change, with many other important properties detailed at ImmutableCollection.
ImmutableCollection	A Collection whose contents will never change, and which offers a few additional guarantees detailed below.
ImmutableList	A List whose contents will never change, with many other important properties detailed at ImmutableCollection.
ImmutableListMultimap	A ListMultimap whose contents will never change, with many other important properties detailed at ImmutableCollection.
ImmutableMap	A Map whose contents will never change, with many other important properties detailed at ImmutableCollection.
ImmutableMultimap	A Multimap whose contents will never change, with many other important properties detailed at ImmutableCollection.
ImmutableMultiset	A Multiset whose contents will never change, with many other important properties detailed at ImmutableCollection.
ImmutableRangeSet	A RangeSet whose contents will never change, with many other important properties detailed at ImmutableCollection.
ImmutableRangeSet.Builder	A builder for immutable range sets.
ImmutableSet	A Set whose contents will never change, with many other important properties detailed at ImmutableCollection.

ImmutableSortedSet	A NavigableSet whose contents will never change, with many other important properties detailed at ImmutableCollection.
ImmutableTable	A Table whose contents will never change, with many other important properties detailed at ImmutableCollection.
Interners	Contains static methods pertaining to instances of Interner.
Maps	Static utility methods pertaining to Map instances (including instances of SortedMap, BiMap, etc.).
Multimap	A collection that maps keys to values, similar to Map, but in which each key may be associated with multiple values.
Multimaps	Provides static methods acting on or generating a {@code Multimap}.
Multiset	A collection that supports order-independent equality, like Set, but may have duplicate elements.
MutableClassToInstanceMap	A mutable class-to-instance map backed by an arbitrary user-provided map.
RangeSet	A set comprising zero or more Range#isEmpty nonempty, Range#isConnected(Range) disconnected ranges of type {@code C}.
Sets	Static utility methods pertaining to Set instances.
Sets.SetView	An unmodifiable view of a set which may be backed by other sets; this view will change as the backing sets do.
Tables	Provides static methods that involve a {@code Table}.
TreeBasedTable	Implementation of {@code Table} whose row keys and column keys are ordered by their natural ordering or by supplied comparators.
TreeMultimap	Implementation of {@code Multimap} whose keys and values are ordered by their natural ordering or by supplied comparators.
TreeRangeSet	An implementation of RangeSet backed by a TreeMap.
