FYI, I've just committed SLIDER-600<https://issues.apache.org/jira/browse/SLIDER-600> for better load/save of histories.
This iteration -saves the map of rolename:priority as a new record, and reloads i -handles loading of a history record with new roles entries than before simply by discarding entries with the new role -is robust against new record types being added to the history. This will allow slider 0.80 to parse, say a slider 0.90 version history without failing. This update does not compare its list of name->ID mappings with the current mapping; that's a future feature. Changing name->ID mapping on a stopped application will simply result in suboptimal placements. -Steve
