API Changelog

🛑 Breaking changes 🛑

• cmd/mdatagen: Enable reaggregation config generation by default; set reaggregation_enabled: false to keep generating metric config with only the enabled field. (#14689)

💡 Enhancements 💡

• cmd/mdatagen: Enforce stricter feature_gates validation in metadata.yaml by default. (#15310) Strict validation can be skipped on a per-gate basis by setting skip_strict_validation: true on the gate entry.

• cmd/mdatagen: Support generating config schema and Go config types for package metadata that defines reusable configs under $defs. (#15235)

• cmd/mdatagen: Generate config documentation table and inject it into README.md between sentinel comments (#14564) When a component defines a config: section in its metadata.yaml, mdatagen now generates a Markdown configuration table and injects it into README.md between:

  The table lists every YAML-visible property (including fields from embedded structs), with type, default value, required status, and description. Nested objects generate sub-tables linked from the parent row. Components whose README lacks the sentinel markers are unaffected.

• pkg/configoptional: Add methods allowing scalar unmarshaling (#15175)

• pkg/scraperhelper: Switch scraperhelper.ControllerConfig to schema-based generated configuration and publish its reusable controller_config schema. (#15258)

• pkg/xconfmap: Add ScalarMarshaler and ScalarUnmarshaler interfaces to allow custom marshaling and unmarshaling of wrapped scalar values. (#15175)

• pkg/xextension/storage: Add Walker interface, WalkFunc type, and SkipAll error value to support iterating over storage key/value entries. (#15190, #15191)

• pkg/xextension/storage: Add Walker interface, WalkFunc type, and SkipAll error value to support iterating over storage key/value entries. (#15190, #15191) A storage Client may optionally implement the Walker interface to allow consumers to range through all stored entries. This enables use cases such as storage migrations and TTL-based garbage collection.

v1.58.0/v0.152.0

🚩 Deprecations 🚩

• pkg/xconfmap: Deprecate xconfmap.Validator and confmap.Validate in favor of confmap.Validator and confmap.Validate. (#15142)

💡 Enhancements 💡

• cmd/mdatagen: Add go_struct.ignore_default flag to suppress default value generation for individual config fields. (#15156) Setting go_struct.ignore_default: true on a config field causes mdatagen to omit that field's default from the generated createDefaultConfig function, emitting nil for pointer fields and configoptional.None for optional fields.

• pkg/confmap: Add the confmap.Validator interface and confmap.Validate function for configuration validation. (#15142)
