v0.1.5

Runtime

• Avoid extra tracing attribute work when NoopTracer is active
• Reuse cheaper branch decisions in the buffered linear runtime hot path
• Prefer the source delivery hook directly for delivery-capable sources
• Add a direct single-sink batch-write fast path in SinkFanOut

Benchmarking

• Split benchmark reporting into dedicated pages for core, Kafka, and Redis
• Keep benchmarks/run.py as the single benchmark entrypoint while moving lane-specific logic into private helper modules
• Expand Redis plugin benchmark coverage with separate SET, XADD, XREADGROUP, and end-to-end stream scenarios
• Refresh benchmark docs so the reports read as release artifacts instead of internal script notes

Documentation

• Rename the core benchmark page from a generic matrix label to a clearer core benchmark report
• Clarify tracing and sink batching notes in the architecture and sink guides
• Refresh plugin benchmark pages so each report uses a consistent, professional structure

Packaging

• Bump agora-etl to 0.1.5
• Update the changelog index to include the 0.1.5 release track
