# 1.61.0 - SDK Sidecar Restricted Security Context, GameServer Health Detection Fix, Fleet Rolling Update Stability, and Memory Leak Resolution.

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

---

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.
