Feb 1, 2026February 2026 recap for microsoft/documentdb gateway: Delivered TLS handshake detection and Unix socket support, with corresponding tests, and updated configuration for Unix socket workflows. Refactored connection handling to generic async streams, improving maintainability and cross-transport compatibility. Updated synchronization point across commits to keep gateway aligned with latest DocumentDB state. Hardened the build pipeline by installing Rust tooling before gateway host build, reducing build failures. Expanded configuration to include Unix socket path, file permissions, and idle timeout for improved security and operability. These changes deliver stronger security, reliability, and faster deployment cycles, with measurable improvements in connection reliability and test coverage.
