January 2026 monthly summary for envoyproxy/ai-gateway focusing on business value and technical execution. Key feature/bug fix delivered: AWS Bedrock Streaming Request Body Mutation Bug Fix that preserves translated request format by removing restoration of the original request body during body mutation. This fixes streaming requests with serviceTier:default at route level and prevents AWS Bedrock 400/serialization errors. Related work includes debugging, root-cause analysis, and code changes across the Body Mutator and translation paths. Delivered with added tests and cross-team collaboration (PR #1812).
