Conversation
From codec to platform: a public protocol registry so a third party can extend the decode walk without forking (#87); decode_frame(), the chain walker, ships with the library instead of living in the README and three copy-pasted test files (#88); every ProtocolError carries structured diagnostics -- protocol, field, offset, frame_offset, expected/actual -- instead of only a formatted string (#91); Packet indexes by protocol type and is hashable, and .payload is deleted outright as the breaking change behind this major bump (#90); a canonical, direction-independent flow key for TCP/UDP conversations (#89); and ICMPv4/ICMPv6.embedded_chain decodes an error message's truncated embedded packet with no try/except (#92).

Summary
Cuts 2.0.0 — Tier 2 of the post-1.3.0 roadmap (#107), now that #104 and all six of its sub-issues (#87, #88, #89, #90, #91, #92) are closed. Mirrors the exact shape of the 1.3.0 release commit (
0f86821):CHANGELOG.md's## [Unreleased]heading becomes## [2.0.0] - 2026-09-04,pyproject.tomlandnetprotocols.__version__bump to2.0.0, anduv.lockis regenerated to match. No functional changes — those already merged in #130, #131, #132 (and earlier this cycle in #125, #126, #127).Why major:#90 deletes
Packet.payloadoutright (it was always exactlybytes(self), a redundant duplicate of__bytes__). Everything else in the tier is additive.What ships in 2.0.0
decode_frame()(Ship decode_frame() — the chain walker belongs in the library #88) — the chain walker ships with the library instead of living in the README and three copy-pasted test files.ProtocolErrordiagnostics (Structured parse diagnostics on ProtocolError #91) —protocol,field,offset,frame_offset,expected/actualon every raise site.Packettype indexing (packet[TCP]),.get(), and hashing;.payloaddeleted (Make Packet pull its weight — type indexing, hashing, and a rename #90, breaking).ICMPv4/ICMPv6.embedded_chain— an error message's truncated embedded packet, decoded with notry/except(A named lax decode mode for deliberately truncated input #92).Verification

Merging this does not publish anything by itself. Per
.github/workflows/release.yml, only a pushedv2.0.0tag on the resulting merge commit triggers CI +uv publishto real PyPI (trusted publishing) — that is a separate, deliberate step after this merges, and I'll confirm with you before pushing that tag since a published version can only be yanked, never replaced.🤖 Generated with Claude Code
