Appendix C: Versioning

The SDK follows semantic versioning independently from the AECS-1 spec.

  • @mvrx/mail 0.x — implements AECS-1 1.0.0 core (parser, threading, content levels)
  • @mvrx/mail 1.0.0 — released when the full SDK surface in this document is stable

The spec version implemented is declared in package.json:

{ "aecs": "1.0" }
Version Date Notes
0.3.0-draft 2026-07-03 Synced to AECS-1 v1.0.0 (Final, 2026-07-03). Added the Implementation Status note (near the top of this document) and Status: Roadmap banners on every section that specifies a module not yet implemented in @mvrx/mail, roadmap annotations on the §2.2 setup bindings and §13§14 examples/extensibility, plus a §11 cross-reference to AECS-1 §7’s security guidance. No normative algorithm text changed.
0.2.0-draft 2026-06-29 Prior draft, written before AECS-1 was finalized.
