Code:

Get rid of struct Time
We just need the milliseconds of current system
time for our needs. This allows to simplify the
API.

No functional change.

Code:

Simplify Option c'tor
No functional change.

Code:

Revert "Simplify Option c'tor"
std::to_string() is C++11 material, not c++03.

So revert the patch.

Code:

Enable link time optimization only when optimizing
Because it is quite slow, skip it when 'optimize' flag is 'no'

No functional change.

Code:

Rename *last to *end
It is a more correct name because it points past the
last move of the list.

No functional change.

Code:

Simplify generate_castle()
Skipping the calls to std::min(), std::man() we get
even a nice speed-up on perft.

No functional change.

Code:

Remove redundancy in move generation
Introduce generate_all_moves() and remove a good
bunch of redundant code.

No functional change.

Changes:

ELO increase is very limited, it is mainly a minor release to flush
the accumulated work. From the user point of view the biggest thing is
that SF should not crash anymore even with many threads because a
nasty SMP bug causing a rare but repetitive crash has been fixed.

1) For people compiling themself the Stockfish bench signature is: 5416292 It means that if you run ./stockfish bench then it should show 5416292 nodes searched. This means that the compile is correct.

2) For people running / using under Android / iPhone with more than one thread, I'd suggest to set "Use Sleeping Threads" option. This allows to save power and battery and strength is practically the same.
