    Generating RBAC rules for the k8s_observer extension in the OpenTelemetry Collector when used in the operator.
    The change addresses the issue where the collector lacked necessary permissions to list and watch Kubernetes resources.

  • auto-instrumentation: Upgrade urllib3 upper limit following Python 3.8 support drop (#3712)

🧰 Bug fixes 🧰

  • collector: added check for maxReplica when minReplica is set in autoscaler (#4160)
    When using the AutoScaler, maxReplica must be set when minReplica is set.
  • target allocator: check CRD availability before registering informers (#3987)
  • target allocator: Allow collector to use TLS Config from Target Allocator with ScrapeConfig (#3724)
    This change allows the target allocator to configure TLS Config for a collector using the ScrapeConfig.

🛑 Breaking changes 🛑

  • pkg/instrumentation: Move pkg/instrumentation to internal/instrumentation (#4140)
  • targetallocator, collector: Remove stable feature gate PrometheusOperatorIsAvailable (#4141)

💡 Enhancements 💡

  • controller: Harmonize CLI and env var configuration to allow setting all configuration (#3565)
    In order of priority, the default configuration is assigned first, overwritten by environment variables and CLI arguments successively.

  • managementState: managementState property on resources is no longer a required field since it has a default value as managed (#4076)

  • operator: Support for Kubernetes 1.33 version. (#4048)

  • target allocator: Adds support for HTML output in the target allocator. (#3622)

  • controller: Support a yaml config file to set all the configuration options exposed by controllers (#3565)

🧰 Bug fixes 🧰

  • target allocator: ensure stable iteration order of target labels when generating hash (#4082)
  • target allocator: Fix OpenShift must-gather for Target Allocator (#4084)
  • opampbridge: Do not register the opampbridge webhook if the CRD is not present (#4070)
  • auto-instrumentation: Fix the bug that k8s.container.name in OTEL_RESOURCE_ATTRIBUTES env is not set correctly for Go the auto-instrumentation when the pod has multiple containers. (#4089)
  • collector: Fix the headless service name in StatefulSet mode to ensure consistent DNS resolution. The ServiceName field in the OpenTelemetryCollector spec can be used to customize the StatefulSet's serviceName. (#4029)
    The ServiceName field in the OpenTelemetryCollector
    spec can be used to customize the StatefulSet's serviceName if needed, while maintaining
    the default behavior of using the headless service name.
  • operator: Remove invalid operator.observability.prometheus feature flag references (#4159)
    Fixed operator installation failure caused by references to the non-existent operator.observability.prometheus feature flag.
    Removed the flag from the bundle and cleaned up API and documentation references.

💡 Enhancements 💡

  • collector: Move validation to be part of the CRD for sidecar mode (#3319)

  • target allocator: Promote the operator.collector.targetallocatorcr feature flag to Beta (#2422)

    As a result of this change, when the target allocator section is enabled in the Collector CR,
    this now creates a TargetAllocator CR instead of generating the manifests directly. Behavior should otherwise be
    unchanged. You can go back to the previous behaviour by passing the
    --feature-gates=-operator.collector.targetallocatorcr command-line option to the operator.

  • collector: Set the default spec.replicas to 1 in the OpenTelemetryCollector CRD. (#4042)

    This default no longer relies on the admission webhook.

🛑 Breaking changes 🛑

  • target-allocator: Switch to Prometheus 3.0 defaults for ScraperProtocols, requires prometheusreceiver >0.120.0 (#3872)

💡 Enhancements 💡

  • target-allocator: Allow to configure ScraperProtocols in prometheus common config (#4000)
  • target allocator: set default target allocator grace period to 30 seconds (#3989)
    The config option collectorNotReadyGracePeriod have been set to 30s by default. The target allocator now waits for 30 seconds before reallocating targets from a collector which isn't Ready.
    Setting this value to 0 will restore previous behaviour.

🧰 Bug fixes 🧰

  • otel-allocator: Remove overwrite of global config ScraperProtocols (#3996)
  • target allocator: Fix user-defined volumes in the TargetAllocator CR (#3992)
  • collector: add terminationGracePeriodSeconds to DaemonSet and StatefulSet specs (#4003)

💡 Enhancements 💡

  • webhook: Allow to run the operator without the OpenTelemetry CRDs present (#3568)
    Skip registering the webhook and keep the operator working in case the OpenTelemetryCollector CRDs are not deployed.

🧰 Bug fixes 🧰

  • collector: Fixes container port duplication for user-provided and operator inferred ports (#3950)
    This patch improves container port collisions when the user defines additional ports in the CR.

    When ports are specified in the CR:

    • If a port number from the CR matches a port inferred from the config, the inferred port is removed
    • If a port name from the CR matches an inferred port name, the inferred port is renamed to "port-{number}"

  • collector: Prevent the operator from overriding the env vars defined by the user in the OpenTelemetryCollector spec. (#3963)
    This change ensures that the operator does not override the environment variables defined by the user in the OpenTelemetryCollector spec.
    It combines user-defined environment variables with automatically inferred ones, giving precedence to user-defined ones.

  • opamp: Fix config loading priority (#3928)

  • target allocator: Fix config loading priority (#3928)

  • collector: Set the statusReplicas field for the DaemonSet (#3930)

  • collector: Fix OpenShift internal collector metrics dashboards to use _total suffix (#3994)
    The following settings (or missing metrics configuration since 0.119.0) exposes metrics with _total suffix:

       service:
     telemetry:
       metrics:
         readers:
          - pull:
            exporter:
              prometheus:
                host: '0.0.0.0'
                port: 8888

    The following settings exposes metrics without _total suffix:

       service:
     telemetry:
         address: 0.0.0.0:8888

  • targetallocator: Do not override the collector namespace from the config file if the environment variable is not set. (#3976)

🛑 Breaking changes 🛑

  • auto-instrumentation: Update recommended resource attributes to match the semantic conventions (#3797)
    This change updates the recommended resource attributes to match the semantic conventions.
    The following attributes have been updated:

    • service.version now uses the docker image digest in addition to the tag
    • the well-known label app.kubernetes.io/part-of for service.namespace has been removed
    • the well-known label app.kubernetes.io/instance has been added (translates to service.name)
    • service.namespace now also uses the Kubernetes namespace name (if resource.opentelemetry.io/service.namespace is not set)

    You can do the following to avoid breaking changes:

    • service.version: Set the version explicitly using resource.opentelemetry.io/service.version
      (not recommended, the version has only been made more specific)
    • service.namespace: Set the namespace explicitly using resource.opentelemetry.io/service.namespace -
      or just rely on the Kubernetes namespace name, which is now the default
    • service.name: If you have enabled useLabelsForResourceAttributes:
      Set the name explicitly using resource.opentelemetry.io/service.name if app.kubernetes.io/instance is used for another purpose

💡 Enhancements 💡

  • target allocator: Specific changes on CRD, Manifest, Controller, etc to allow specifying value for collector grace period (#3781)
  • auto-instrumentation: Increase default instrumentation memory limit to 256Mi (#3479)

🧰 Bug fixes 🧰

  • collector: Fix the default configuration for the internal metrics endpoint (#3730)
  • collector: Set the default endpoint to 0.0.0.0:13133 for the collector health check extension (#3825, #3688)
