Summary

This release changes the matching algorithm for all queues except 1v1. We need this to be able to provide queues with higher team sizes than 2v2. There should also be a noticeable increase in match quality in the already existing 2v2 queue. Additional queues will probably be deployed after the next server release, because currently there is no functionality to change game options like the share condition for individual queues yet.
In addition the rating initialization was reworked from the hardcoded 2v2 initialization. Now any rating can use any other rating as an initializer. This will allow more flexibility when adding additional ratings in the future.
Lastly we did some bugfixes and some internal cleanup.

Other Noteworthy Changes

  • When a user logs in from a second location the server will terminate the first connection, so the reconnect loop between the two clients doesn't happen anymore.

Developer Notes

  • The server now sends RabbitMQ messages after each rating change of a player, allowing the league service to finally calculate the league scores.
  • The server now accepts match_ready commands from the client. So the client's connection won't get closed for violating the server protocol.
