# 1.12.0 - Release Candidate

LLMS index: [llms.txt](/site/llms.txt)

---

This is the 1.12.0-rc release of Agones.

A few things to note in this release:
- The `GameServer` CRD now includes the full `PodTemplateSpec` json schema, to provide better up-front validation.
  This should be entirely backward compatible, but in case you run into issues, the helm configuration option
  `gameservers.podPreserveUnknownFields` is available to disable validation and field pruning.
  - If you are using Helm, you might need to update your Helm version and/or do a clean install to apply this update to
    your cluster if you already have a version of Agones installed, due to the size of the CRD update.
- `SDKWatchSendOnExecute` has been moved to Beta, so by default you will get a copy of the most recent `GameServer`
  information with your initial `SDK.WatchGameServer(...)` request.
- The ability to apply port allocation to multiple containers has moved from Beta to Stable!
