# Dependent log filters, GraphQL operations in Discover Services, and a leaner services list

> Log Builder filters narrow based on earlier selections, GraphQL-named operations show up in the Discover Services Operations tab, and the services list hides the environment column when it doesn't add value.

### Improvements

- **Logs**
  - Log Builder filters now chain — picking a cluster scopes the service-name filter to only services in that cluster, and so on down the line, instead of listing every service in the org
- **Discover**
  - Services → Operations tab now surfaces GraphQL-named operations (`query ContestsJoined`, `mutation CreateTeam`, etc.) from Apollo Server instrumentation; previously these spans were invisible because they lacked `http_status_code`
- **Alerting**
  - `event_state` is now optional on the Change Events API (defaults to `start`), so AWS CodePipeline, ECS, and other EventBridge sources can post events directly without a Lambda shim

### Fixes

- **Discover**
  - Clicking a GraphQL operation from Overview → Top slow operations routed to an incorrect URL and didn't select the right operation
  - Memory usage color stayed green at 96% on the hosts list instead of turning red
