June 2026: Implemented WebSocket support in the Rust runtime for vercel/vercel, enabling real-time bidirectional communication in the vercel_runtime crate. Core changes include enabling per-connection HTTP upgrades and ensuring OnUpgrade is delivered to user code, aligning the Rust runtime with Python and Node.js runtimes. Crate bumped to 2.3.0 to support the feature and publish workflow. Validation shows production handshake with two WSS clients and a dev workflow with a single connection, verifying end-to-end functionality and setting the stage for parity and broader real-time capabilities.

Monthly summary for 2025-08 focusing on oven-sh/bun. Key feature delivered: xxHash64 now supports a 64-bit seed, expanding seed handling beyond the previous 32-bit limit. A test was added to verify behavior with seeds larger than 2^32, improving confidence in edge-case hashing scenarios. A critical bug fix ensured xxHash64 accepts seeds larger than u32, stabilizing hashing behavior across platforms. Overall, this work enhances hash reliability and flexibility for users relying on large seed values in production environments.

Month 2024-12 — Focused bug fix for vercel/next.js that improves static data route routing reliability. Implemented escaping for the '.' in '.json' within the route regex to prevent unintended request paths and routing errors for static data routes. This targeted change enhances routing correctness, reduces potential production incidents, and improves developer experience when working with static data assets. Commit 7061f9428f692cc3de006b70bf85daa6fd7893a0 (PR #73850) demonstrates precise, traceable work.
