Changelog

[2.3.0] - 2026-03-11 — Pipeline v4

Added

• ChecksumCodec — CRC32 integrity: append on encode, verify+strip on decode, Error on mismatch
• RateLimitCodec — Token bucket algorithm (burst-tolerant, refills over time)
• TagCodec — Attach channel ID for mux routing, drop wrong-channel frames on decode
• Pipeline::chain() — Compose two pipelines into one
• Pipeline::describe() — Human-readable dump (dedup → compress → encrypt)
• Error propagation tested — corrupt checksum → PipelineResult.errors
• 474 total tests (+13 new)

[2.2.0] - 2026-03-11 — Pipeline v3

Added

• PipelineResult — returns frames + collected errors + consumed count
• StageMetric — per-stage frames_in/frames_out/consumed/errors observability
• ReassemblyCodec — reassemble chunked frames (counterpart to SlicerCodec)
• ConditionalCodec — wrap any codec with runtime enable/disable toggle
• Pipeline::signal(key) — preset: dedup→compress→encrypt
• Pipeline::media(mtu) — preset: compress→slicer
• Pipeline::metrics() — per-stage counter snapshot
• Slicer↔Reassembly roundtrip verified
• 461 total tests (+12 new)

[2.1.0] - 2026-03-11 — Pipeline v2

Added

• CodecOutput::Many — codecs can fan-out (1 frame → N frames)
• EncryptCodec — XOR cipher encrypt/decrypt adapter
• FilterCodec — drop frames by type (FilterCodec::drop_control())
• Codec::reset() — clear internal state on reconnect
• Pipeline::encode_all/decode_all — batch frame processing
• SlicerCodec rewritten — real MTU chunking via Many
• Full roundtrip test — Compress→Encrypt→encode→decode→verify
• 449 total tests (+11 new)
