You have failed to comply with the GPL as you have not copied the licence in your source code. Please rectify as soon as possible. Have a read of Copying.txt in the Stockfish root folder. Including the Authors and Contributors files is also considered good form.

I'm not going into a discussion whether the GPL is any good. All I'll say is that there is the obvious issue of a missing license which must be provided as per section 5:
b) The work must carry prominent notices stating that it is released under this License and any conditions added under section 7. This requirement modifies the requirement in section 4 to “keep intact all notices”.
One doesn't have to like the license - but you have to follow it.

Apart from that, the modifications are not only useless but worsen the engine significantly:

https://tests.stockfishchess.org/tests/ ... b0007fdf44
https://tests.stockfishchess.org/tests/ ... b0007fdff2

Save yourself some time and hassle by not bothering with Stockfish clones that fail to provide you with any significant test.
