Can you provide information on the security fixes? The Doc is pretty vague.

Thank you for adding the All years option for Holidays. The main thing still missing is the ability to specify time of day routing on Holidays. eg: During Holiday time inbound route does X between 8am and 10am, Y between 10am and 5pm, and Z between 5pm and 11pm.
