🛑 Breaking changes 🛑

• iisreceiver: Enable IIS Application Pool state and uptime metrics by default. (#34924)
  WARNING: This change enables the iis.application_pool.state and iis.application_pool.uptime metrics by default.
  This may cause a significant increase in the number of metrics collected if you have many application pools.
  If you are concerned about the number of metrics, you can disable these metrics in your configuration.

• kineticaexporter: Remove the kineticaexporter (#38911)

• exporter/loki: The Loki Exporter component has been removed from the repo and is no longer being published as it has been deprecated since 9th July 2024. (#41413)
  Users of the lokiexporter can migrate to using an OTLP exporter. See #33916

🚩 Deprecations 🚩

  Improve internal metrics telemetry consistency:
  kafka_broker_throttling_duration is deprecated in favor of kafka_broker_throttling_latency
  kafka_exporter_latency is deprecated in favor of kafka_exporter_write_latency
  kafka_exporter_messages is deprecated in favor kafka_exporter_records

  If the HttpCheckTLSCertRemaining metric is enabled and the endpoint is HTTPS, it will collect the certificate metrics.

• httpcheckreceiver: Remove unnecessary status codes (#38564)
  The httpcheckreceiver now removes the http.status_code attribute from httpcheck.status metrics
  when the metric value is 0, as per the feature request to avoid redundant status codes.

• prometheusremotewriteexproter: Adds additional metrics to the Prometheus Remote Write Exporter when RW2 enable. The new metrics are:

• otelcol_exporter_prometheusremotewrite_written_samples: Number of Prometheus Samples that were successfully written to the remote write endpoint.

• otelcol_exporter_prometheusremotewrite_written_histograms: Number of Prometheus Histograms that were successfully written to the remote write endpoint.

• mysqlreceiver: Support query-level collection. (#40965)
  Added query sample collection. The query will gather the queries that were currently running at the moment when scraping is happening.
  The number of collected queries can be configured. This will enable user to have better understanding on what is going on with the database.
  This enhancement empowers users to not only monitor but also actively manage and optimize their MSSQL database performance based on real usage patterns.

• mysqlreceiver: Add the total number of buffer pool pages (#41252)

• prometheusremotewriteexproter: Adds wal pipeline lag metric to the Prometheus Remote Write Exporter. The new metric is:

• otelcol_exporter_prometheusremotewrite_wal_lag: WAL pipeline lag.

The frequency of recording pipeline lag can be configured with lag_record_frequency
(#39556)

• oidcauthextension: Add support for multiple OIDC providers. (#40854)

• oracledbreceiver: Support query-level log collection, fetching query samples. (#37478)
  With the introduction of query level log collection, details about currently running queries can be collected.
  The maximum number of queries to be collected can be configured. This feature helps the user to have a better understanding of the database operations.

• oracledbreceiver: Support query-level log collection, fetching top N query metrics. (#37478)
  With the introduction of query level log collection, the oracledbreceiver can now send metrics for Top N queries,
  filtered based on the highest CPU time consumed. The number of queries can be configured. This helps the user to have
  a better understanding of the database operations.

• pkg/ottl: Add support for combining scope with other OTTL contexts. (#39308)
