v0.75.0

🛑 Breaking changes 🛑

• datadogexporter: Graduate exporter.datadog.hostname.preview feature gate to Stable. (#20286)

• pkg/ottl: Add typed getter for pcommon.map and update related functions to use it. (#19781)
  Using the impacted functions, such as keep_keys or replace_all_patterns, without a pcommon.map will now result in an error. Only pass these function paths that result in a pcommon.map or set ErrorMode to IgnoreError.

• pkg/ottl: Updates ConvertCase, ParseJSON, Split, and Substring to use StringGetter (#19137)
  Affected components: transformprocessor, filterprocessor, routingprocessor. It is HIGHLY recommended to use each component's error_mode configuration option to handle errors returned by these functions.

• pkg/ottl: Adds new StringLikeGetter for converting values to string for use. (#19782)
  Concat now converts more types to string instead of ignoring them. IsMatch now converts []byte to string using hex.EncodeToString(v).

🚩 Deprecations 🚩

• datadogexporter: Deprecate metrics::histograms::send_count_sum_metrics in favor of metrics::histograms::send_aggregation_metrics. (#20285)
  Toggling metrics::histograms::send_count_sum_metrics will now send .min and .max metrics when available.

🚀 New components 🚀

• awss3exporter: Add new AWS S3 exporter. (#9979)
• servicegraphconnector: Add servicegraph connector to the build. (#20452)

• awsecscontainermetricsreceiver: Add ServiceName from task metadata endpoint (#19728)

• mdatagen: Warnings can now be specified in metadata.yaml to be included in the generated status table. (#20242)

• translator/loki: Normalize label names so they follow the Prometheus label names standard (#14113)
  Loki doesn't support label names containing dots. |
  Users had to convert dot-separated attributes into underscore-separated attributes before promoting them to Loki labels. |
  From now on users can drop relabeling from their configuration. All dots in label names will be replaced with underscores automatically before sending request to Loki.

• mongodbatlasreceiver: Add support to collect organization events. (#19449, #20308)
