The generalized linear model system is now part of the standard distribution. The :display methods for all model objects and the print-matrix function have been changed to use the new ~ G format implementation.
At the moment the number of digits printed is fixed at 6. I may make this a user-settable option.
The function eigen is now based on the EISPACK rs routine.
The function reset-system can be used to reset the state of various internal system parameters. If you write your own top level loop, you can call this when your loop is restarted if it looks like it is needed.
The need for this function is not quite clear yet -- it may be dropped.
The function system-has-windows returns non- nil if a window system is available at runtime. This should be used on UNIX systems rather than a readtime method, such as #+windows.
