Changelog

• base: Deprecated the Throwables methods lazyStackTrace and lazyStackTraceIsLazy. They are no longer useful on any current platform. (6ebd7d8)
• collect: Added a new method ImmutableMap.Builder.buildKeepingLast(), which keeps the last value for any given key rather than throwing an exception when a key appears more than once. (68500b2)
• collect: As a side-effect of the buildKeepingLast() change, the idiom ImmutableList.copyOf(Maps.transformValues(map, function)) may produce different results if function has side-effects. (This is not recommended.) (68500b2)
• hash: Added Hashing.fingerprint2011(). (13f703c)
• io: Changed ByteStreams.nullOutputStream() to follow the contract of OutputStream.write by throwing an exception if the range of bytes is out of bounds. (1cd85d0)
• net: Added @CheckReturnValue to the package (with a few exceptions). (a0e2577)
• net: Added HttpHeaders constant for Access-Control-Allow-Private-Network. (6dabbdf)
• util.concurrent: Added accumulate/update methods for AtomicDouble and AtomicDoubleArray. (2d875d3)
