Re: New engine releases & news H2 2024
No, no. It hasn't been discontinued. But when I started working on Blunder my primary goal was to reach 2600 Elo on the CCRL, which I managed to achieve. So with that goal meet, for now, most of my work on Blunder will be fixing bugs, cleaning up the code, and making it more useful for the communityGabor Szots wrote: ↑Sat Dec 28, 2024 11:40 amHas Blunder been discontinued?algerbrex wrote: ↑Sat Dec 28, 2024 4:49 am The first version of my new chess engine Eques has been released:
