Version , Release 0.9

• The program detects instabilities in the calculation by monitoring the value of entropy and confirming that it is monotonically decreasing. If not, diagnostic messages are written out.
• When the user issues a TSTP signal (CTRL-Z) from the terminal, the program will behave as if convergence was achieved, write the current map and gracefully exit.
• When the program is called as "graphent" (normally through a symbolic link to "GraphEnt"), it enters a very quiet mode in which only error and diagnostic messages are written out.
