Release Notes - v2.168.0

TL;DR:

Version 2.168.0 is a stability and performance release. It fixes a infinite recursion bug in response handling (#​1490), fully migrates core packages from async/lodash to native modern JavaScript patterns, and introduces a more robust typed event system and certificate management architecture.

✨Features

• Server: Added channelSecured event for post-handshake notifications [af7ef34].

🐛Bug Fixes

• Core: Prevented infinite recursion in send_response when chunking fails (#​1490) [51ef025].
• Secure Channel: Implemented fallback to the latest valid token when a request's token expires [ae65dea].
• Server: Deferred channel shutdown until after the ApplyChanges response is sent [8484b98].
• Address Space: Fixed address-space-base imports and applied security hardening [d636f0c].
• Maintenance: Resolved various TypeScript and Biome violations across the codebase [16302c4, 45a1406, 887a42d, 1372b5c].
• Tests: Hardened server shutdown tests [c834243], added TokenStack fallback coverage [823f38d], and increased T73 secure channel renewal token lifetime to reduce flakiness [a13bbb0].

🔧 Refactoring & Improvements

• Performance: Replaced async library [3269940] and lodash [b99520d] with native async/await, Promises, and targeted alternatives.
• Type Safety: Unified certificate chain providers [49b8736] and implemented typed EventEmitter<T> patterns for server events [1f7040e].
• Structure: Split conformance testing into focused modules [e4c5eb9] and cleaned up the address space conformance package [168a8f6].
• Transport: Enhanced type safety and removed unsafe patterns in the transport layer [785d89f].
• Security: Simplified push certificate management [dab64e9].
• Debugability: Internal channel callbacks are now hidden from the debugger for a cleaner debugging experience [e0d2b40].
• Testing Infrastructure: Hardened leak detector for Mocha 12 and tsx [c7170e5].

🧹 Chores

• Updated Biome formatting [465eb93] and fixed misused Mocha timeout configurations [eac92cc].
