Research at intermediate depth if LMR is very high

After a fail high in LMR, if reduction is very high do
a research at lower depth before teh full depth one.
Chances are that the re-search will fail low and the
full depth one is skipped.

Hello,

Would anyone be so kind as to explain what

Merge remote-tracking branch 'upstream/master' means?

Does this mean that all changes made to the original non egtb engine is automatically applied to the engine that supports egtb?

Thank you.

New option Syzygy50MoveRule. Set to false to let tablebase probes
ignore the 50-move rule. This is useful for correspondence chess.
