- /api/1.3/types `(GET,POST,PUT,DELETE)`
- Fair Queuing Pacing: Using the FQ Pacing Rate parameter in Delivery Services allows operators to limit the rate of individual sessions to the edge cache. This feature requires a Trafficserver RPM containing the fq_pacing experimental plugin AND setting 'fq' as the default Linux qdisc in sysctl.
- Traffic Ops rpm changed to remove world-read permission from configuration files.
- Backup Edge Cache group: If the matched group in the CZF is not available, this list of backup edge cache group configured via Traffic Ops API can be used as backup. In the event of all backup edge cache groups not available, GEO location can be optionally used as further backup. APIs detailed here [here](http://traffic-control-cdn.readthedocs.io/en/latest/development/traffic_ops_api/v12/cachegroup_fallbacks.html)
