• contrib: Remove deprecated signalfx receiver from the contrib distribution (#​1551)
• packaging: Prevent service being started/enabled upon install for rpms (#​1334)
  This brings behaviour inline with usual expectations for rpm packages which usually leave this up to the system administrator.

🚀 New components 🚀

• cardinalityguardianprocessor: Add Cardinality Guardian processor to the OpenTelemetry Collector Contrib. (#​1549)

💡 Enhancements 💡

OpenCode Dependabot Risk Review

Schema: local-stack.dependabot-risk.v1

Decision: NEUTRAL
Risk: MEDIUM
Automerge allowed: false
Update type: semver-minor
Ecosystem: docker

Summary

Renovate PR bumps otel/opentelemetry-collector-contrib from 0.156.0 to 0.157.0 (minor). Release notes flag two breaking changes: removal of the deprecated signalfx receiver and a change to RPM package install behavior. The signalfx receiver is not referenced anywhere in this repo's otel configuration, so the first breaking change has no direct impact. The RPM change is irrelevant for Docker deployments. Only the source docker-compose.yml is modified; generated stacks/observability.yml is not changed in this PR and would need regeneration via stackctl.sh. No stateful services, workflows, secrets, or deployment scripts are affected.

Changed runtime artifacts

Image / dependency	From	To	Risk note
otel/opentelemetry-collector-contrib	0.156.0	0.157.0	minor update with explicit breaking changes in release notes: removal of deprecated signalfx receiver and RPM packaging behavior change; signalfx receiver is not used in this repo's otel config.yaml, but manual config compatibility verification is warranted

Runtime impact

Expected rolling service update of the otel-collector container. No stateful data migration required. Telemetry collection may have a brief interruption during the rolling update. The removal of the signalfx receiver has no impact as it is not configured. Manual verification of the collector config after update is recommended.

Breaking change assessment

Release notes for v0.157.0 explicitly list two breaking changes: (1) removal of the deprecated signalfx receiver from the contrib distribution, and (2) RPM packages no longer start/enable the service on install. The signalfx receiver is not used in this repo's observability/otel/config.yaml, so the first change has no local impact. The RPM change is irrelevant for Docker-based deployments. No other breaking changes were identified that would affect this repo's configuration.

Required checks

• ./stackctl.sh generate
• ./stackctl.sh sync
• ./stackctl.sh up --dry-run --no-logs
• Verify otel-collector starts successfully and telemetry pipelines are healthy

Manual follow-up

• Confirm otel-collector logs show no configuration errors after update
• Verify telemetry data flow (traces, metrics, logs) is uninterrupted

OpenCode risk gate: changes requested. Risk: medium. Reason: Renovate PR updates otel/opentelemetry-collector-contrib from 0.156.0 to 0.157.0 (minor). Release notes explicitly list two breaking changes: removal of the deprecated signalfx receiver from the contrib distribution and a change to rpm packaging behavior (service no longer started/enabled upon install). Both the source compose file and the generated observability stack are updated. Manual review is required to verify the local-stack configuration does not use the removed signalfx receiver and to assess any impact on the observability pipeline.
