- A `EN_DEMANDPATTERN` parameter was added as the index of the default time pattern used by demands with no specific pattern assigned. It can be set or retrieved with the `EN_setoption` and `EN_getoption` functions, respectively, and is saved to file when the `EN_saveinpfile` function is called. - A `EN_DEMANDPATTERN` parameter was added as the index of the default time pattern used by demands with no specific pattern assigned.
