• exporter/prometheus: Produce exemplars for monotonic sum metrics (i.e. counters in Prometheus) when available (#18201)
  This could be a breaking change if you already have enabled OpenMetrics format for the Prometheus exporter and have enabled exemplar ingestion in your Prometheus scraper. To ensure names and types are generated correctly according to the OpenMetrics conventions, you should run your collector with --feature-gates=pkg.translator.prometheus.NormalizeName

  Currently, the only way to add configurative functionality to mdatagen is by using a bunch of WithResourceAttributesSettings options to the constructor.
  This PR changes the first argument to the NewMetricsBuilder constructor to be of type MetricsBuilderConfig,
  which is a new class that wraps both MetricsSettings and ResourceAttributesSettings, and may be (hopefully) easily extended with more
  configuration in the future.

🧰 Bug fixes 🧰

• receiver/purefareceiver: Updating documentation to include required configuration fields. (#14886)

• clickhousexporter: Clickhouse string type cast function of insert flow changed because of missing span values. (#17834)

• prometheusremotewriteexporter: Export _created metric for Summary, Histogram and Monotonic Sum metric points if StartTimeUnixNano is set. (#17412, #12426)
  The export of tbe _created metric is configurable in the Prometheus remote write exporter. It is disabled by default.

• clickhouseexporter: Fix "no such host" error when the DSN hostname contains the database name (#16476)

• oracledbreceiver: the resource attribute oracledb.instance.name now captures the database name. (#17850)

• signalfxexporter: Make sure the metadata updater is tied to the exporter itself, so it can tack on the exporter lifecycle. (#17976)

• mdatagen: Fixing templateFS to work on windows systems (#17576)
  This fix will allow the command to work as a static binary without needing reference to the templates on disk.

• pkg/ottl: Fix issue where IsMatch returned an error if the target val was nil (#17572)

  • Affected components
    • filterprocessor
    • routingprocessor
    • transformprocessor

• batchperresourceattr: Optimize batch processor attribute and don't reset the caller's instance, instead make a copy of the original resource attributes (#17835)

• receiver/prometheusreceiver: Use _created metrics, if present, to set StartTimeUnixNano for Sum, Histogram and Summary metrics. (#12428)
  If the _created metric was present in the Histogram, Summary or Counter
  metric family, only then its values is used to set StartTimeUnixNano on the
  relevant OTLP metric and dropped afterwards. Otherwise, it is converted to the
  monotonic OTLP Sum metric.
  This behaviour is disabled by default. Use the receiver.prometheusreceiver.UseCreatedMetric
  to enable it.

• exporter/prometheusremotewriteexporter: Export exemplars for the Monotonic Sum metric. (#17573)

• windowseventlogreceiver: Fix panic that can occur when event is larger than current buffer size. (#17879)

• windowseventlogreceiver: Fixed a panic that could create an empty buffer due to incorrect use of unsafe pointers in syscall. (#17878)
  Fixed a potential panic due to a syscall indicating a that the event buffer should resize to 0. The next used of that resized buffer would result in an index out of bounds panic.

  Also, added a safety check for buffer resize cases that if the syscall indicates it needs the buffer size to be 0, an error will be returned.
