Downtime deletion by hostgroup previously matched hostgroups containing the specified "hostgroup_name" rather than matching the exact name. For example, deleting the downtime for 'hostgroup_A' also deleted downtimes for 'hostgroup_A_Z', causing incorrect deletions. We now match hostgroup names exactly, which corrects this behavior.
As a result, users will only delete downtimes for the exact hostgroup they specify, preventing accidental removal of downtimes for similarly named hostgroups. No action is required from users to benefit from this fix.
No script changes are necessary.
