Undici's latest release addresses critical HTTP/2 body transmission bugs while Node core continues refactoring its profiling and debugger infrastructure for maintainability.

Undici v8.2.0 [1] dropped overnight with fixes for HTTP/2 body handling on non-expectsPayload methods and corrected the WASM SIMD environment variable logic that was blocking optimization paths. The release also switches to native addAbortListener instead of polyfilling, reducing surface area. In parallel, Undici's pool management got tighter [2] [3]: stale client replacement now respects connection limits while preserving pool capacity, preventing resource leaks in long-lived services. The dispatcher selection in BalancedPool [4] also shed redundant scans — targeted cleanup for high-throughput scenarios. On the Node core desk, the team is systematically refactoring for clarity: profiling helpers split from util into dedicated files [5], debugger components moved to separate modules [6], and FFI's DynamicLibrary now protected against premature garbage collection [7]. Temporal also joined the frozen intrinsics list [8]. Meanwhile, the CI infrastructure migration from JSON-based OpenSSL matrix to Nix definitions [9] provides cleaner variation handling for future patching scenarios.
