v1.4.2

Changes

• Fix: illegal moves in info lines. Since v1.4 the adapter checks the lines from Psion's analysis display and picks the promotion piece Psion does not show. Moves into check were not considered, so a queen could be chosen where only a knight promotion works, and GUIs may then reject the line as an illegal PV. Moves that leave the own king in check, and castling out of or through check, are now rejected too.
• Less CPU use at fast time controls. After Psion moves, the emulation now stops after about 0.35 s instead of 0.8 s, so it also stops when the opponent replies quickly.

Psion Chess itself is not included: see data/README.md in the package for where to download it.
