Re: Orion 0.9 release
Thanks to all of you ! ... PS. My only problem is that I had to create a new Orion 0.9 folder to avoid a 'collision' (because the networks are named the same). @Gabor : I'm sorry about that. I did not anticipate that someone could put several versions of Orion in only one directory (it can make sens...

New Orion release : v0.4 !
I'm happy to announce the availability of a new version of my little UCI engine : v0.4 ! I concentrated all my efforts to improve the search function, and the new version should clearly be better than the previous one (I hope in the range of 50-100 elo). A BMI2 version of the engine is also provided...
