🛑 Breaking changes 🛑

• operator: Change default operator.admissionWebhooks.autoGenerateCert.recreate from true to false. (#2261)
  The self-signed webhook certificate is now reused across helm upgrades instead of being
  regenerated every time. The default certificate validity is 10 years (certPeriodDays: 3650),
  so rotation per-upgrade is not required for most deployments.
  To restore the previous behavior (regenerate certificate on every upgrade), set:

  operator:
    manager:
      rolling: true # recommended
    admissionWebhooks:
      autoGenerateCert:
        recreate: true

  Note: manager.rolling: true is recommended with recreate: true — it restarts the operator
  pod so it loads the new certificate promptly. Without it, there is a delay before the
  webhook server picks up the new cert, during which Instrumentation CR requests may fail
  with x509 errors.

• agent: Drop destination_service_namespace from Istio metric attributes (#2275)
  Users running the chart with autodetect enabled have hit the dimension limit
  for Istio metrics. This fix drops the destination_service_namespace metric
  dimension to avoid hitting the dimension limit and dropping the data point entirely.

💡 Enhancements 💡

• operator: Add Job-based Instrumentation CR installation Job. (#2261)
  The Instrumentation CR is deployed as a regular Helm resource by default. A new option
  instrumentation.installationJob.enabled deploys the CR via a Kubernetes Job that waits
  for webhook readiness before applying the CR, with built-in retry. This is the recommended
  option for Helm v4 or environments with slow operator startup.
  See Auto-instrumentation Install for details.

🧰 Bug fixes 🧰

• eks_addon: Fixed journald receiver issues in the EKS Add-on by mounting required shared library paths used by journalctl and aligning the directory structure with EKS node conventions. (#2260)
