🚀 Release Notes — v2.162.0

This release focuses on performance improvements, memory optimizations, and protocol robustness, with additional updates to OPC UA 1.05 nodesets, better TypeScript generation, and fixes in client-side extension object handling. Several hot paths (transport, secure channel, chunk manager, variant encoding) have been optimized to reduce allocations and improve throughput under load.

✨ TL;DR

• Significant performance & memory optimizations in transport, secure channel, chunk manager, and variant encoding
• Updated OPC UA 1.05 nodesets with smarter fallback for ComplexDataType handling
• Fixed client-side ExtensionObject creation with subtyped fields
• Improved TypeScript generator correctness for inherited generic members
• Added tests and documentation for packet assembly and reconnection scenarios

⚡ Performance Improvements

• 3ff99c3 — Avoid unnecessary buffer copies in the transport layer (transport)
• 6347ba6 — Faster buffer encoding/decoding for Variants (variant)
• 6339b87 — Reduce memory retention by not keeping raw message chunks unless performance monitoring is enabled (transport)
• e99143f — Zero-copy padding removal and length reduction using Buffer.subarray (secure-channel)
• 30cf813 — Optimize padding byte writing using Buffer.fill() (~10% throughput gain) (chunk-manager)

🧠 Protocol & Feature Enhancements

• d1697eb — Detect ComplexDataType2017 profile to automatically force OPC UA 1.04 extraction when required (client / datatype extraction)
• e62d0e9 — Update nodeset XML files to the latest OPC UA 1.05 revisions (nodesets)
• 8343203 — Add documentation and tests for packet assembler (packet-assembler)

🐛 Bug Fixes

• 17ea9bb — Fix client-side creation of ExtensionObjects containing subtyped fields (client)
• 332fbed — Fix typo in “already used nonce” error message (server)
• 7149387 — Fix inherited member type compatibility in the TypeScript generator (generator) 👉 Fixes GitHub issue #​1472

🧪 Tests & Tooling

• e230cef — Add end-to-end tests exploring reconnection behavior after keepalive failures (end2end-test)
• 50c0cf9 — Minor adjustment to run_all_mocha_tests.js (tests)

🧹 Maintenance & Cleanup

• 4e06dc1 — Dependency updates
• da12830 — Additional package updates
• 67da20e — Improved warning messages
• 415b89e — Version bump to v2.162.0

📌 Note

This release brings measurable gains in performance and memory efficiency, especially for high-throughput clients and servers, while continuing the transition toward OPC UA 1.05 compliance with robust backward-compatibility handling.
