Other Changes
- Software changes require array index instead of integer value (expand description).
- Dynamic control packet format has changed. For an expanded description of the changes and how to convert from the v1.1 format to the v2.0 format, see Dynamic PRACH Scheduling and Legacy Dynamic Control Packet.
