v1.12.9 - Matchmaker tweaks

This version continues to hone in the matchmaker behavior to find an optimal balance of wait time vs game quality across all rating ranges. New players and high rated players will now be matched a bit more cautiously to try and improve game quality. In addition the map pool used for map selection will now be determined by the average displayed rating of the team as opposed to the minimum. This means it will now be possible for you to get maps from map pools which are above your rating in TMM if you are matched with higher rated players.

Developer notes

Since the map pool selection uses average rating it will not necessarily be possible to show an accurate map pool in the client.

Deployment notes

In this release the Dockerfile was rewritten and does some things different internally. Most notably the code is no longer copied to /code and is instead installed to the system as a python package. Only main.py (formerly server.py) is copied to /code and serves as the main entrypoint for the application. These changes should still be fully compatible with the old configuration in faf-stack, however, they could potentially break more customized setups.

v1.12.8 - Achievements Fix

Sends achievement updates over RabbitMQ instead of trying to contact the API directly. This means changes to the API will no longer break the achievement update code in the future. This requires the API to also listen for updates over RabbitMQ before achievements will work again.

What's Changed

• More info logging by @Askaholic in #951
• Issue/#946 Update achievements over RabbitMQ by @Askaholic in #949
• Configure server contexts through yaml config by @Askaholic in #945

v1.12.7 - More bugfixes

The main changes in this release are a fix to the matchmaker that was allowing matches with too low quality, and changing mutual draws to be rated as regular draws as opposed to being unrated. This was due to some confusing behavior when a player died and the rest of the players agreed to a mutual draw.

• Issue/#876 Use rabbitmq 3.9 by @Askaholic in #944

v1.12.4 - Out of Steam

Summary

Removes any checks for steam id from the server as the user service which supplies the OAuth tokens checks for ownership so any check in the lobby server is redundant and legacy. Also adds a configuration flag to disable the hello password login in order to not bypass the check from the user service

What's Changed

• Remove steam id checks from server by @Sheikah45 in #912
• Issue/#914 configuration refresh by @Askaholic in #915
• Update dependencies by @Askaholic in #916

Fixes a bug where games could be rated multiple times.

What's Changed

• Issue/#909 Dependency updates by @Askaholic in #910
• Issue/#903 Fix games being rated multiple times by @Askaholic in #904

v1.12.2 - Minor bugfixes

Summary

This release contains mostly just minor housekeeping things. The biggest change was a removal of the custom __eq__ and __hash__ implementations for Player objects. This was causing some really obscure bugs especially with the party system where it was possible to be in a party by yourself but not have party owner permissions. Hopefully this won't happen anymore.

What's Changed

• Issue/#860 Update README by @Askaholic in #869
• Set game_id_counter to 0 if no games by @Brutus5000 in #896
• Issue/#897 config housekeeping by @Askaholic in #899
• Fix integration tests by @Askaholic in #898
• Issue/#893 player hash implementation by @Askaholic in #895

v1.12.0 - Matchmaker timeouts for failed games

Summary

This release aims to improve the matchmaker experience, since the addition of the 4v4 queues made connection issues a significant factor. Now, people who repeatedly cause a matchmaker game to fail will be temporarily put into a matchmaker cooldown period where they cannot join any queues until their timeout expires. The timeout periods are currently defined like this:

1 violation: None
2 violations: 10 minute cooldown
3+ violations: 30 minute cooldown

The violation count is reset after 1 hour of no failed matches.

In addition, there are some bug fixes to tracking of matchmaker state that could cause the wrong game to be cancelled if one of the player's network connections timed out, as well as change to the pop timers that reduces the threshold for number of players in the queue before the pop interval is shortened.

Developer Notes

• Clients should consider the teams field in the game_info message to be deprecated and use teams_ids instead
