Known issues

  • When entering a new position after undoing or redoing moves, the move list in the main screen is not cleared.

UCI versions

  • The “en passant” square given via FEN position string is discarded erroneously.

Android

  • A Clang issue with the compiler requires a small workaround for 64 bit. As to keep the versions in line, the impacted feature has been disabled for all Android builds.
