Version: v0.12.11

Releases

All PEAC Protocol releases follow semantic versioning. Every release is published to npm under the @peac scope, and all packages in the monorepo share the same version number.

v0.14.4 (May 19, 2026)​

Composition Surfaces​

  • Runtime governance composition recipe: docs/SOLUTIONS/agt-peac-composition.md — generic normalizeRuntimeGovernanceEvent API, vendor-neutral (not tied to one platform); canonical line "Harnesses control execution. PEAC records bounded work. Logs stay local; PEAC records travel."
  • Runnable runtime-composition-records example: end-to-end vendor-neutral demo using @peac/adapter-runtime-governance; smoke test verifies round-trip
  • Edge verification recipe: docs/SOLUTIONS/verify-at-the-edge.md — generic pattern first, Cloudflare + Docker in stability-class table; cites docs/specs/RESOURCE-LIMITS.md for 256 KiB body cap, 5,000 ms JWKS timeout, 100 keys cap, TTL bounds 60..86,400 s
  • Evaluation and harness record recipes: docs/SOLUTIONS/eval-platform-records.md + docs/SOLUTIONS/harness-records-quickstart.md — three recipe commands verified exit 0 with valid interaction-record+jwt JWS
  • MCP composition guide: docs/SOLUTIONS/mcp-composition.md — cites merged SEPs 2468, 2484, 2577, 2106; 30 doc-truth assertions; explicit "PEAC does NOT" boundary block (8 items)
  • .NET quickstart verifier: committed-fixture offline verifier for Ed25519 records (net10.0, NSec.Cryptography); NOT a .NET SDK or NuGet package
  • Go middleware chi adapter parity: sdks/go/middleware/chi/chi_test.go + README.md — brings chi to parity with echo/gin/nethttp adapters

Versioning policy​

Breaking changes

PEAC Protocol is currently in the v0.x series. During this phase:

  • Breaking changes are allowed between minor versions, with migration guidance in the changelog
  • The wire format (peac-receipt/0.1) is stable across all v0.x releases
  • All packages share the monorepo version -- when one package updates, they all update

At v1.0 (earned, not scheduled):

  • Wire format changes to peac-receipt/1.0
  • Public API surface freezes with full backward compatibility commitment
