Startdate and enddate parameter values now default to 365 days in the past and the current day respectively, and enforce a maximum range of 365 days across all results endpoints - startdate can be set more than 365 days in the past, but the enddate value can be no more than 365 days after the start_date value.

This validation update was planned for deployment in the near future, but brought forward at short notice to address a rapidly growing degradation in the overall service performance due to increasing and unsustainable levels of bare or wide date range complex results queries.

All parameter options and response models remain unchanged.

We apologise for any inconvenience caused due to this update.
