Again, more than a week since an update...but lots of updates!

Oct 30-Nov 16

Merge Traversable into Iterable (Brian). Having a separate "Traversable extends Iterable" no longer added value.

Cleanup on Optional (Brian). Move all construction to factories (empty() and of(value)); add ifPresent(Block).

Remove INFINITE_SIZE flag (Paul.) Nothing was acting on it.

More Spliterator implementations (Mike). Serial and parallel implementations of Spliterator for ArrayList and Vector.

Integration from JUC (Mike). Now uses default FJ pool.

Addition of Iterator.forEach (Brian).

More lambdafied getAndUpdate/updateAndGet methods for Atomics (Brian). First round had left out the AtomicXxxFieldUpdaters.

Major cleanup of API used to build Streams (Brian and Paul.) Mostly Streams.stream(...) and Arrays.{stream,parallel,iterator,spliterator} now.

Removal of StreamAccessor (Paul). Spliterator is enough, no need for a separate abstraction.

Explicit unordered() op (Paul). This allows a stream that has an encounter order (e.g., a List) but doesn't care about the order to instruct downstream ops to ignore order, allowing potentially more efficient execution.

More parallel implementations (Brian). Now all ops have a parallel implementation! Though some could be improved.

More point lambdafication. Added BufferedReader.lines(), more Comparators support, static helper methods that can be converted with method refs (e.g., Intger::sum), log(Level, Supplier).

New slice() op (Brian). Combination of limit and skip. Consolidated implementation of LimitOp/SkipOp into SliceOp.

First cut at primitive streams (Paul.) Added IntStream with implementation of basic int ops.

Renames of SAMs (Mike.)

As you've seen, we've been starting the process of reviewing the chunks that have fewest dependencies. So first was the SAMs, then pieces like Comparators and Spliterator, etc. We'll be putting each chunk back to the jdk8 repos as each chunk is reviewed.
