# OpenFeature flagd/v0.17.0

> CI/CD & App Delivery · 2026-09-25

A feature and maintenance release with a breaking sync-metric rename and a security-related dependency update. It also includes readiness correctness fixes, response compression, and additional sync instrumentation.

## Action needed
- **[security]** The `go.opentelemetry.io/otel/sdk` module update
  - The `go.opentelemetry.io/otel/sdk` module was updated to v1.45.0 in the release.

## Check if affected
- **[breaking]** Server-side sync metric names
  - Applies if you use either `feature_flag.flagd.sync.active_streams` or `feature_flag.flagd.sync.stream.duration`.
  - The server-side sync metrics `feature_flag.flagd.sync.active_streams` and `feature_flag.flagd.sync.stream.duration` were renamed to `feature_flag.flagd.sync.server.active_streams` and `feature_flag.flagd.sync.server.stream.duration`. Client sync metrics were added alongside them.
