AI Summary
This core release v1.5.13 includes significant provider improvements including Azure provider migration to v1 API, a new ConfigMarshallerPlugin interface for plugin config control, and OpenTelemetry attribute alignment with GenAI semantic conventions. The release also contains numerous bug fixes for Bedrock (cache, response conversion, reasoning blocks, passthrough), Gemini tool schema, and Anthropic tool handling.
Key Highlights
- Azure provider migrated to v1 API with removal of `api_version` from `AzureKeyConfig`
- New `ConfigMarshallerPlugin` interface allows plugins to control config storage and redaction
- OpenTelemetry attribute keys aligned with GenAI semantic conventions, emitting both legacy and canonical attributes
- Multiple Bedrock fixes: cache stripping, empty text block handling, reasoning blocks preservation, and passthrough request restoration
- Fixes for Gemini tool schema passthrough and structured output + tools conflict resolution
Breaking Changes
- Azure provider `api_version` field removed from `AzureKeyConfig` - users must update their configuration to use the v1 API
New Features
- Azure provider migration to v1 API with `api_version` removal from `AzureKeyConfig`
- ConfigMarshallerPlugin interface for plugin-controlled config storage and redaction
- Forward `x-bf-eh-*` extra headers as `gen_ai.request.extra_header.*` span attributes
- OpenTelemetry attribute alignment with GenAI semantic conventions (legacy and canonical attributes emitted)
