v1.61.0

This is the 1.61.0 release of Agones.

This release focuses on strengthening GameServer lifecycle reliability, hardening security for the SDK sidecar, and continuing internal code modernization. Key updates include a restricted-compatible security context for the SDK server sidecar, fixes for GameServer health detection and fleet auto scaling edge cases, a memory leak fix on GameServer deletion, a Helm-conditional fix for CRD patch metadata, and continued migration of the codebase to a new internal errors package. Together, these changes improve production stability for game server operators and keep the project's build tooling current.

• Helm 3 to Helm 4 Upgrade: Agones tooling and charts have been upgraded from Helm 3 to Helm 4. Operators managing Agones installations via Helm should ensure their deployment pipelines and Helm client versions are compatible with Helm 4.

• Restricted-Compatible Security Context for SDK Sidecar: The SDK server sidecar now supports a security context compatible with Kubernetes' restricted Pod Security Standard, making it easier for operators to run Agones in clusters that enforce strict security policies.

• GameServer Health Detection Fix: GameServers are now correctly marked Unhealthy when the game container terminates but the Pod itself remains Running, closing a gap where crashed game processes could previously go undetected.

• Memory Leak Fix on GameServer Deletion: Resolved a memory leak that occurred when a GameServer was deleted, improving controller stability over long-running clusters.

• Fleet Rolling Update Fix: Active GameServerSet replica counts are now clamped at zero during fleet rolling updates, preventing invalid negative replica states during scale-down transitions.

• E2E Test Stability on GKE Autopilot: SendTCP now retries TCP dialing on GKE Autopilot clusters, improving reliability for automated end-to-end test runs.

• SDK Server maxItems Fix: The gameservers.lists.maxItems setting is now correctly plumbed through to the SDK server, ensuring configured list size limits are honored.

• New Website Logo (Snapser): Welcome to Snapser! Their logo has been added to the Agones homepage showcasing organizations using Agones in production.
