🛑 Breaking changes 🛑

• pkg/stanza: Improve parsing of Windows Event XML by handling anonymous Data elements. (#​21491)
  This improves the contents of Windows log events for which the publisher manifest is unavailable. Previously, anonymous Data elements were ignored. This is a breaking change for users who were relying on the previous data format.

• processor/k8sattributes: Graduate "k8sattr.rfc3339" feature gate to Beta. (#​28817)
  Time format of k8s.pod.start_time attribute value migrated from RFC3339:
  Before: 2023-07-10 12:34:39.740638 -0700 PDT m=+0.020184946
  After: 2023-07-10T12:39:53.112485-07:00
  The feature gate can be temporary reverted back by adding --feature-gate=-k8sattr.rfc3339 to the command line.

• filelogreceiver: Change "Started watching file" log behavior (#​28491)
  Previously, every unique file path which was found by the receiver would be remembered indefinitely.
  This list was kept independently of the uniqueness / checkpointing mechanism (which does not rely on the file path).
  The purpose of this list was to allow us to emit a lot whenever a path was seen for the first time.
  This removes the separate list and relies instead on the same mechanism as checkpointing. Now, a similar log is emitted
  any time a file is found which is not currently checkpointed. Because the checkpointing mechanism does not maintain history
  indefintiely, it is now possible that a log will be emitted for the same file path. This will happen when no file exists at
  the path for a period of time.

• dockerstatsreceiver: cpu.container.percent metric is removed in favor of container.cpu.utilization (#​21807)

• awsxrayexporter: Convert individual HTTP error events into exceptions within subsegments for AWS SDK spans and strip AWS.SDK prefix from remote aws service name (#​27232)

• azuremonitorexporter: Added connection string support to the Azure Monitor Exporter (#​28853)
  This enhancement simplifies the configuration process and aligns the exporter with Azure Monitor's recommended practices.
  The Connection String method allows the inclusion of various fields such as the InstrumentationKey and IngestionEndpoint
  within a single string, facilitating an easier and more integrated setup.
  While the traditional InstrumentationKey method remains supported for backward compatibility, it will be phased out.
  Users are encouraged to adopt the Connection String approach to ensure future compatibility and to leverage the broader
  configuration options it enables.
