December 2025: Delivered a security-conscious enhancement to anthropic-sdk-go by introducing Bearer Token Authentication for AWS Bedrock, enabling API-key-based access without AWS credentials. Implemented via WithBearerToken(token, region), the feature bypasses AWS SigV4 when a bearer token is present and works with both streaming and non-streaming modes. Included comprehensive tests and example programs, along with environment variable support (AWS_BEARER_TOKEN_BEDROCK) and documentation updates to support enterprise adoption. This reduces credential management overhead, accelerates onboarding, and broadens Bedrock usability in corporate settings.
