This release adds opening book functionality to Megalodon. This is currently toggleable through the UCI option OwnBook. By default, it is set to false. In order to successful use this functionality though, it is required to have a openings.txt file in the same directory that you run Megalodon. The file must be formatted such that on each new line there is a sequence of moves notated with the UCI format, nothing else. We have provided an example openings.txt file in the openings folder.
