8. Versioning

This specification follows semantic versioning (MAJOR.MINOR.PATCH).

• Breaking changes to the NormalizedEmail schema increment the major version.
• Additive, non-breaking changes increment the minor version.
• The processing.specVersion field in each normalized object SHOULD record the major and minor version used (e.g. "1.1").

Current version: 1.1.1

Release History

Version	Date	Notes
1.1.1	2026-10-05	Adds informative Appendix C (storage and indexing): hot/warm/cold split by access pattern, mailbox-scoped hashed keys, indexes for the core reads, idempotent writes, payload budgets, security and retention. No normative change; processing.specVersion stays "1.1".
1.1.0	2026-10-05	Adds §4.3.1 (content preservation): cleanup MUST NOT remove authored lines, including bottom-posted and inline replies; divider lines are not quote boundaries; signature removal is limited to short trailing blocks; an empty cleanup result falls back to text. Adds optional processing.cleanFallback. Fixes the contradiction between §4.3 and Appendix A over content.raw, which retains quoted history. Adds §10 conformance points 8–9 and content-preservation fixtures. Implementations that keep only the text above the first quote marker were AECS-1.0-conformant and are not AECS-1.1-conformant.
1.0.0	2026-07-03	First stable release. Adds §4.1.1 (synthetic messageId), §6.1 (Date parsing), and clarifies §5.4 fallback-hash inputs.
1.0.0-draft	2026-06-29	Initial public draft.
