## What changed

**1. Added: Update** (monitoring) · 2026-10-21 05:07 UTC

```diff
+ We’ve finished updating the services that power Buildkite so they no longer trust the affected eMudhra certificates. No action is needed from customers for Buildkite hosted services. For components that run in customer infrastructure, we still recommend upgrading to the releases listed in our previous update (Buildkite agent v4.7.0 / v3.138.2, Buildkite CLI v3.64.2, and bktec v3.3.1). We’re continuing to release updates for the other binaries we distribute and will post them here as they ship.
