* Made improvements to server network performance
* Added two new matchmaking regions in South America (Chile and Peru)
* Removed Captains Draft mode from ranked matchmaking. There were too few players in this mode which caused excessive wait times, imbalanced matches, and potential for MMR abuse.

The Singapore matchmaking region will be undergoing some changes next week. There will be a maintenance period from the 13th until the 16th Singapore time. On the 14th the region will be entirely unavailable, and during the other times it will be operating under limited capacity (fewer servers available for usage). We will be rebuilding the clusters on new server hardware and retiring the old server hardware. On the network side, we will be improving the router architecture, as it is currently too susceptible to packet loss under high load.
