Igel 2.5.0 at https://github.com/vshcherbyna/igel/releases/tag/2.5.0 (binaries for Linux, macOS and Windows).

This release brings various improvements in code quality as well as strength improvements in search, evaluation and tt management. As of this release Igel uses OpenBench as a primary testing system and I would like to specially thank Andrew Grant for supporting Igel development on OpenBench.

What's new:

- Implement OpenBench support
- Implement BMI2 instruction support for faster search
- Implement prefetch instruction support for faster search
- Implement ponder support
- Implement improved sudden death time control management
- Implement use of hugepages in Linux OS
- Implement more efficient tt management and re-write tt replacement scheme to 'always replace'
- Implement proper handling of chopper moves
- Implement improved king safety evaluation
- Implement improved weights management
- Implement symmetric evaluation function
- Set tt score in qsearch
- Set bestmove as a hashmove by default
- Bugfix for knight outpost
- Bugfix for depth skipping in smp mode
- Implement pst based evaluation for connected passers
- Bugfix for probcut in check
- Factor in 'improving' even when in checks
- Adjust bestscore from tt score
- Bugfix shuffling of moves at root in smp mode

In case of bug reports, questions, discussions please ask them at main Igel topic at viewtopic.php?p=847306#p847306 to prevent polluting this thread.
Many thanks for new Igel Volodymyr. :) :)
