v0.2.1

Changes

• Fix native peer teardown so an unclosed RTCPeerConnection with a created data channel no longer keeps the Node.js process alive.
• Drop late native datachannel callbacks after RTCPeerConnection.close() and close attached native channels during cleanup.
• Stabilize the UDP mux close-delivery regression assertion that runs before the full Conformance matrix.

Validation

• CI required: passed on main
• CodeQL C/C++ and JavaScript/TypeScript: passed on main
• Full Conformance: passed on the v0.2.1 tag
• Release workflow: passed, including all prebuild targets, checksum assets, and npm publication with provenance
• Published Install: passed for Linux glibc/musl, macOS x64/arm64, and Windows x64/arm64

v0.2.0

Highlights

• Adds the typed nonstandard namespace for focused libdatachannel extensions: ICE UDP mux listener, pre-construction peer configuration, explicit local ICE credentials, remote fingerprint access, and PEM certificate import.
• Keeps the W3C-facing RTCPeerConnection, RTCDataChannel, and setLocalDescription() behavior unchanged.
• Documents implementation-specific APIs under docs/nonstandard.md and records the W3C compatibility boundary in docs/divergences.md.
• Adds focused tests and TypeScript coverage for the new nonstandard surface.

Validation

• CI required: passed on main
• CodeQL C/C++ and JavaScript/TypeScript: passed on main
• Feature-branch Conformance: passed before release prep

v0.1.7

Changes

• Preserve FIFO message delivery when a native RTCDataChannel batch arrives while older messages are queued for JavaScript dispatch.
• Improve Windows host-runtime compatibility, including delayed Node symbol resolution for Bun and other compatible hosts.
• Stabilize Windows native dependency caching and ARM64 release builds.
• Add sharded conformance execution and harden CI evidence validation.
• Tighten release automation defaults while preserving npm trusted publishing and provenance.

Validation

The release passed the full pull-request and post-merge CI matrix across Linux, macOS, Windows, Node.js 20/22/24, Windows ARM64, Chrome E2E, WPT smoke, package artifact validation, and both CodeQL language analyses.

The version tag starts the independent full Conformance workflow; publication does not wait for that long-running matrix.

v0.1.6

Changes

• verify release prebuilds with SHA-256 checksums before installation
• reject malformed archives and wrong OS, architecture, or Linux libc targets
• install validated native addons atomically
• strengthen required CI and independent JavaScript/C++ CodeQL analysis
• keep strict tag Conformance as independent release evidence instead of blocking publication

No public WebRTC API changes are included.

Full Changelog: v0.1.0...v0.1.1

v0.1.0

Stable release candidate promoted from the v0.1.0.alpha.

Performance Improvements

• Reduced binary data-channel send overhead.
• Reduced binary message copies in the native bridge.
• Added native batching for data-channel message dispatch.
• Improved data-channel message throughput and setup latency.
• Sped up peer setup and data-channel ID checks.
• Deferred native data-channel close handling to reduce close-path overhead.

Correctness Fixes

• Preserved data-channel batch ordering.
• Fixed empty message batch flush indexing.
• Restored per-send bufferedAmount behavior.
• Synced bufferedAmount during paired local delivery.
• Stabilized data-channel close timing.
• Gated initial data-channel messages so early bursts are delivered correctly.
• Fixed message listeners added during onmessage so they receive later messages in the same burst.

Native Layer

• Improved Node-API event dispatch internals.
• Batched native data-channel message events before crossing into JavaScript.
• Reduced ArrayBuffer copying by moving binary payload ownership into the JavaScript-facing event object.
• Tuned libdatachannel configuration for the data-channel profile.

Testing

• Added regression coverage for message listeners registered during message dispatch.
• Kept the selected WPT data-channel profile as the conformance target.
