 Change log:
 
+8/12/2018 4.0
+Complete redesign of the internal logic, to make interruption of thinking
+actually work. The engine thread is made responsible for parsing the GUI
+commands that require the engine to be idle. These commands are passed to
+it from the GUI thread through an internal command queue. The engine thread
+can peek in this queue when a search terminates and it enters the idle or
+pondering state. It only goes reading the ponder output after all queued
+commands are processed. This way the GUI thread is sensitive to input all
+the time, and can instantly handle all commands by either processing those
+that can be done during search, and queueing the others. In the latter case
+it can abort an ongoing search to divert the attention of the engine thread
+back to the command queue.
+ Other changes are:
+Added option to force the engine to ponder if force mode (for OTB tournaments).
+Produce a compliant error message for unknown commands.
+Fix time increment in ponder-on games (which was subtracted rather than added).
+Set UCCI newgame option after initial isready handshake rather than before it.
+Suppress spurious sending of 'uxinewgame' in UCCI mode.
+Suppress 'setup' command in the standard variants 'suicide' and 'losers'.
+Add support for robbobases and Scorpio bitbases as EGT flavors.
+Support extended UCI info-string-variant command that can set board size.
+Assume engines with UCI_Chess960 option but no UCI_Variants play only Chess and
+Chess960, and not xiangqi or shogi.
