v0.4.0

• chore: bump all versions to 0.4.0
• feat(sdk): align Python and Node SDKs to v0.3 API

v0.3.0

• style: apply rustfmt
• build: optimize release profile, sync SDK versions to 0.3.0, add CI caching
• feat(lane): EventStream Stream impl, manager subscribe(), lane pressure events
• docs: update README for v0.3 — feature flags, event catalog, bug fixes

• refactor: feature-gate optional modules, remove anyhow from production deps

v0.2.3

Bug Fixes

• fix: remove tracing spans from async paths for Send compatibility with tracing 0.1.41+

The tracing crate v0.1.41+ introduced PhantomNotSend in Span, making any async function holding a Span across .await boundaries return a !Send future. This broke tokio::spawn compatibility. All info_span!/.instrument()/.enter() patterns in manager.rs and queue.rs have been replaced with plain tracing::info! events that fire immediately without holding state across await points. Telemetry recording via OpenTelemetry metrics is fully preserved.

v0.2.2

• feat: add npm platform packages for per-platform binary distribution

v0.2.1

• chore: bump version to v0.2.1
• fix: rename npm package to @a3s-lab/lane

v0.2.0

• chore: bump version to v0.2.0
• feat: add Python SDK, Node SDK, and GitHub Actions CI/release pipeline
• docs: update README formatting
• feat: add OpenTelemetry telemetry and OtelMetricsBackend

v0.1.0 — Initial Release

A3S Lane v0.1.0

Priority-Based Command Queue — Lane-based async task scheduling with configurable concurrency.

Features

Phase 1: Core Queue

• Priority-based lane system (Critical → Low)
• Configurable per-lane concurrency limits
• Async command execution with Tokio
• Event-driven architecture with EventEmitter

Phase 2: Reliability

• Persistent storage backend (JSON file)
• Configurable retry policies (fixed, exponential backoff)
• Dead Letter Queue (DLQ) for failed commands
• Graceful shutdown with in-flight command completion

Phase 3: Scalability

• Multi-core parallel execution
• Queue partitioning
• Rate limiting
• Priority boosting for starved commands

Phase 4: Observability

• Queue metrics (depth, throughput, latency)
• Health check API
• Structured event logging

Stats

• 212 tests passing
• 14 commits since initial development
