Also I'm posting an update soon that will also fix the error on line 100 in search.cpp. That is something that was simplified away by the SF team which I am keeping for now.

without the recent thread stack size bug fix for macOS, SF and its derivatives would barf (crash) on the above position when using many threads - many thanks to both Marco Costalba for his patch correcting this and also to Joost VandeVondele for his research into the issue that was specific only to macOS.

And also , my fork of Joe Ellis' matefinder was updated with the thread stack size bug fix for macOS and is current with dev-SF

Downloaded the new package .. :cry: .. error plus the warning re-appeared.
No worries as I can remove the 'cp' line - as for the warning I'll wait for the official release .. :D

Hello,

Igel 1.4 is released at https://github.com/vshcherbyna/igel/releases/tag/1.4

What's new:

- Implemented support for syzygy tablebases (uci options SyzygyPath and SyzygyProbeDepth)
- Changed the move ordering during root search
- Changed evaluation of late end-games
- Minor memory optimisations (decrease memory usage by ~2 Mb)
- Cosmetic changes: report tbhits, proper node count from primary & lazy smp threads

Strength compared to Igel 1.2, Igel 1.3 (various configurations) and other engines:

Igel 1.4 64 POPCNT vs Igel 1.3 64 POPCNT
tc=all/60+0.6
threads=11 (for Igel 1.4)
threads=1 (for Igel 1.3)
hash=6144
book=up to 8 moves for both engines
EGTB=3-4-5 piece (used only by Igel 1.4, because Igel 1.3 does not support EGTB)
Score of Igel 1.4 64 POPCNT vs Igel 1.3 64 POPCNT: 118 - 13 - 54 [0.784] 185
Elo difference: 223.72 +/- 46.36 (I am not sure this increase is going to be observed when playing against other engines with similar params, but I did not tested them much)

Igel 1.4 64 POPCNT vs Igel 1.2 64 POPCNT
tc=all/10+0.1
threads=1
hash=1024
book=up to 8 moves for both engines
EGTB=3-4-5 piece (used only by Igel 1.4, because Igel 1.2 does not support EGTB)
Score of Igel 1.4 64 POPCNT vs Igel 1.2 64 POPCNT: 883 - 440 - 677 [0.611] 2000
Elo difference: 78.25 +/- 12.52

Igel 1.4 64 POPCNT vs Igel 1.2 64 POPCNT
tc=all/10+0.1
threads=1
hash=1024
book=up to 8 moves for both engines
EGTB=disabled for both engines
Score of Igel 1.4 64 POPCNT vs Igel 1.2 64 POPCNT: 813 - 506 - 686 [0.577] 2005
Elo difference: 53.62 +/- 12.39

book=up to 8 moves for both engines
EGTB=disabled for both engines
Score of Igel 1.4 64 POPCNT vs Igel 1.3 64 POPCNT: 727 - 536 - 740 [0.548] 2003
Elo difference: 33.23 +/- 12.09

Igel 1.4 64 POPCNT vs Igel 1.3 64 POPCNT
tc=all/10+0.1
threads=1
hash=1024
book=up to 8 moves for both engines
EGTB=3-4-5 piece (used only by Igel 1.4, because Igel 1.3 does not support EGTB)

Elo difference: 43.83 +/- 12.44

Here go some shallow tests with CCRL 40/40 time controls:

Igel 1.4 64 POPCNT vs GreKo 2018 (2708)
tc=40/960 (CCRL 40/40)

EGTB=3-4-5 piece (used by Igel and WyldChess)
Score of Igel 1.4 64 POPCNT vs WyldChess: 19 - 18 - 13 [0.510] 50
Elo difference: 6.95 +/- 84.36
